Danfoss Industrial Refrigeration extends a range of stainless steel valves for special application requirements.

The valve range includes for valve sizes DN 15 mm (1/2 in.) to DN 125 mm (5 in.) in angleway and straight execution and includes:

The range has been extended to meet the increased demand brought about by

1. the need for higher protection of external surfaces on valves and ﬁttings

2. the need to meet developments in the way that plants are being designed.

In certain speciﬁc areas such as outdoor applications and corrosive atmospheres, such as coastal installations, there is a need for high surface protection to prevent failure due to corrosion.

Today's food safety standards often call for daily treatment with detergents to protect against bacteria growth, again producing a need for high surface protection.

Shut-oﬀ valves SVA-S/L SS

Features SVA-S/L SS

In certain speciﬁc areas such as outdoor applications and corrosive atmospheres, such as coastal installations, there is a need for high surface protection to prevent failure due to corrosion.

Today's food safety standards often call for daily treatment with detergents to protect against bacteria growth, again producing a need for high surface protection.

SVA-S/L SS are angleway and straightway stainless steel shut-oﬀ valves, which are designed to meet all industrial refrigeration application requirements.

The valves are designed to give favourable ﬂow characteristics and are easy to dismantle and repair when necessary. The valve cone is designed to ensure perfect closing.

• Applicable to HCFC, HFC, R717 (Ammonia), R744 (CO2) and all ﬂammable refrigerants.

• Optional accessories:

– Heavy duty industrial hand wheel for

frequent operation.

– Cap for infrequent operation.

• Available in angleway and straightway versions with Standard neck or Long neck (DN 15 to DN 40) for insulated systems.

• Designed to give favourable ﬂow conditions.

• Internal backseating enables replacement of the spindle seal whilst the valve is active, i.e. under pressure.

• Housing is made of stainless steel approved for low temperature operations.

Connections

Available with the following connections:

• Butt-weld DIN (EN 10220) DN 15 – 125 (½ – 5 in.)

• Butt-weld ANSI (B 36.19M) DN 15 – 100 (½ – 4 in.)

Housing

Made of stainless steel approved for low temperature operations.

Valve cone

The valve cone can be turned on the spindle, thus there will be no friction between the cone and the seat, when the valve is opened and closed. A teﬂon tightening ring provides perfect sealing at a minimum closing momentum.

Spindle

Made of polished stainless steel, ideal for O-ring sealing. Furthermore, parts of the spindle are heat treated to obtain anti-abrasive / adhesive properties.

Packing gland

The stainless steel packing gland comprises a spring loaded seal packing gland which ensures a perfect tightness in the range:

-60 – 150 °C / -76 – 302 °F.

The packing glands are equipped with a scraper ring to prevent penetration of dirt and ice into the packing gland.

Pressure Equipment Directive (PED)

The stainless steel valves are approved and CE marked in accordance with the Pressure Equipment Directive - 97/23/EC.

Installation

It is recommended that the valves be installed in the direction of ﬂow indicated by the arrow on the valve body. The valve can be installed in the opposite direction but this slightly reduces the kv-value (Cv-value).

The valve is designed to withstand high internal pressure. However, the piping system in general should be designed to avoid liquid traps and reduce the risk of hydraulic pressure caused by thermal expansion.

For further information refer to installation instructions for SVA-S/L SS.

Hand-operated regulating valves REG-SA SS and REG-SB SS

Features REG-SA SS and REG-SB SS

In certain speciﬁc areas such as outdoor applications and corrosive atmospheres, such as coastal installations, there is a need for high surface protection to prevent failure due to corrosion.

Today's food safety standards often call for daily treatment with detergents to protect against bacteria growth, again producing a need for high surface protection.

REG-SA SS and REG-SB SS are angle-way and straight-way hand-operated regulating valves, which act as normal stop valves in closed position.

The valves are designed to meet the strict quality requirements on refrigerating installations speciﬁed by the international classiﬁcation societies and are carefully designed to present favourable ﬂow conditions and accurate linear characteristics.

The valves are equipped with vented cap and have internal backseating enabling the spindle seal to be replaced with the valve still under pressure.

• Applicable to HCFC, HFC, R717 (Ammonia), R744 (CO2), Propane, Butane, Iso-Butane and Ethane. R717 Heat Pump and Propylene applications with replaced O-ring.

• Designed to give favourable ﬂow conditions.

• Internal backseating enables replacement of the spindle seal whilst the valve is active, i.e. under pressure

• Housing is made of special cold resistant stainless steel approved for low temperature operations.

• Easy to disassemble for inspection and service.

• Butt-weld DIN and ANSI connections.

• Max. operating pressure: 52 bar g / 754 psig

• Tem perature range:

-60 – 150 °C / -76 – 302 °F.

• Compact and light valves for easy handling and installation.

• Classiﬁcation: DNV, CRN, BV, EAC etc. To get an updated list of certiﬁcation on the products please contact your local Danfoss Sales Company.

• Butt-weld DIN (EN 10220) DN 15 - 40 (½ - 1½ in.)

• Butt-weld ANSI (B 36.19M) DN 15 - 40 (½ - 1½ in.)

The cone

The valves are available in two diﬀerent versions – REG-SA SS with an A cone and REGSB SS with a B cone. The A cone is designed for expansion lines, while the B cone is designed for regulating purposes e.g. liquid lines.

The valve cone is designed to ensure perfect regulation and provide an extensive regulating area. Irrespective of the refrigerant used, it is easy to obtain the correct capacity. A cone seal ring provides perfect sealing at a minimum closing momentum.

The valve cone can be turned on the spindle, thus there will be no friction between the cone and the seat when the valve is opened and closed.

Spindle

Made of polished stainless steel, ideal for O-ring sealing. Furthermore, parts of the spindle are heat treated to obtain anti-abrasive/adhesive properties.

Packing gland - REG-SA SS and REG-SB SS

The stainless steel packing gland comprises a spring loaded seal packing gland which ensures a perfect tightness in the range:

-60 – 150 °C / -76 – 302 °F.

The packing glands are equipped with a scraper ring to prevent penetration of dirt and ice into the packing gland.

Installation

Install the valve with the spindle up or in horizontal position. The ﬂow must be directed towards the cone.

Computation and selection

Introduction

In refrigeration plants, regulating valves are primarily used in liquid lines in order to regulate the ﬂow of refrigerant. The valves can, however, also be used as expansion valves. From a calculation point of view the two ﬁelds of application are very diﬀerent.

Normal ﬂow is the term used to describe the general case where the ﬂow through the valve is proportional to the square root of the pressure drop across it and inversely proportional to the density of the refrigerant (Bernouillis equation).

Location of valve in system (marked with grey)

Hot gas by-pass & defrost line

Dry suction line

Wet suction line

REG-SA/SB SS

This relationship between mass ﬂow, pressure drop and density satisﬁes the majority of all valve applications with refrigerants and brines.

Normal ﬂow is characterised by turbulent ﬂow through the valve without any phase change. The following capacity curves are based on the above mentioned assumption.

Application of the regulating valves outside the normal ﬂow area will reduce the capacity of the valve considerably. In such cases it is recommended to use "DIRcalc™" (Danfoss Industrial Refrigeration calculation programme).

Example 1.

Refrigerant: R 717 Refrigerant ﬂow: 2200 kg/h Pressure drop:∆p = 0.5 bar

The above mentioned example is illustrated on the following ﬂow rate diagram and shows that REG-SB SS 15 and 20 with cone B can be used. The main rule is that nominal regulation range should be below 85% opening degree. If the arrowline is crossing 2 cone curves, the smaller cone should be selected if opening degree < 85%.

The example is only correct if the density of the

refrigerant is approx. 670 (kg/m3), and there must

be no build-up of ﬂash gas in the valve.

Example 2.

Brine, density ρ: 1150 [kg/m3] Brine ﬂow G: 2,700 [kg/h] Pressure drop ∆p: 0.5 [bar]

In this example it is not possible to use the selection diagrams (ﬁg. 3 and 4) as the refrigerant in question is not included.

Calculation example:

Required kv-value CA = 0.00132 (from fig. 18) kv = CA × G kv = 0.00132 × 2,700 [kg/h] = 3.56 [m3/h]

Calculation factor C

Use the curves of the kv-values instead (ﬁg. 1 - 2)

and calculate the required kv by means of the

formulas in the "Introduction" passage at the

beginning of this chapter. Alternatively calculate

the kv-values by means of the calculation factor CA

(ﬁg. 7) and the ﬂow rate diagram (in this example:

ﬁg. 8) as per the following calculation example.

Check & stop valves and check valves SCA-X SS and CHV-X SS

Features SCA-X SS and CHV-X SS

In certain speciﬁc areas such as outdoor applications and corrosive atmospheres, such as coastal installations, there is a need for high surface protection to prevent failure due to corrosion.

Today's food safety standards often call for daily treatment with detergents to protect against bacteria growth, again producing a need for high surface protection.

SCA-X SS are check valves with a built-in stop valve function. CHV-X SS are check valves only.

The valves are designed to open at very low diﬀerential pressures, allow favourable ﬂow conditions and are easy to disassemble for inspection and service.

The valve cone has a built-in ﬂexibility to ensure a precise and tight closing towards the valve seat.

A well balanced dampening eﬀect between the piston and the cylinder gives an optimal protection during low loads and against pulsations.

• Applicable to HCFC, HFC, R717 (Ammonia), R744 (CO2), Propane, Butane, Iso-Butane and Ethane. R717 Heat Pump and Propylene applications with replaced O-ring.

• Designed to give favourable ﬂow conditions.

• Internal backseating enables replacement of the spindle seal whilst the valve is active, i.e. under pressure (SCA-SS)

• Housing is made of special cold resistant stainless steel approved for low temperature operations.

• Easy to disassemble for inspection and service.

• Butt-weld DIN and ANSI connections.

• Max. operating pressure: 52 bar g / 754 psig

• Tem perature range:

-60 – 150 °C / -76 – 302 °F.

• Compact and light valves for easy handling and installation.

• Classiﬁcation: DNV, CRN, BV, EAC etc. To get an updated list of certiﬁcation on the products please contact your local Danfoss Sales Company.

Available with the following connections:

• Butt-weld DIN (EN 10220) DN 15 – 40 (½ – 1 ½ in.)

• Butt-weld ANSI (B 36.19M) DN 20 – 40 (¾ – 1 ½ in.)

Housing

Made of stainless steel approved for low temperature operations.

Valve cone

Valve cone with built in metallic stop - prevents damage to teﬂon ring in case of overtightening.

Damping chamber

The chamber is ﬁlled with refrigerants (gas or liquid), which provides a damping eﬀect when the valve opens and closes.

Spindle (SCA-X SS)

Made of polished stainless steel, which is ideal for O-ring sealing.

Packing Gland (SCA-X SS)

The “full temperature range” packing gland is the standard for the entire SVL platform. This ensures perfect tightness throughout the whole temperature range:

-60 – 150 °C / -76 – 302 °F.

Pressure Equipment Directive (PED)

The SCA-X SS/CHV-X SS valves are approved according to the European standard speciﬁed in the Pressure Equipment Directive and are CE marked.

For further details / restrictions - see the product instruction.

Installation

The valve must be mounted vertically with the cone downwards.

The valve is designed to resist very high internal pressure. However, the piping system in general should be designed to avoid liquid traps and reduce the risk of hydraulic pressure caused by thermal expansion.

For further information refer to installation instructions for SCA-X SS/CHV-X SS.

If cold refrigeration oil having low viscosity enters and settles in the damping chamber, problems with the check valve may arise. Consequently, it may be necessary to modify the valve for more viscous liquids by enlarging the hole to the damping chamber.

Strainers FIA SS

Features FIA SS

In certain speciﬁc areas such as outdoor applications and corrosive atmospheres, such as coastal installations, there is a need for high surface protection to prevent failure due to corrosion.

Today's food safety standards often call for daily treatment with detergents to protect against bacteria growth, again producing a need for high surface protection.

FIA SS strainers are a range of angle-way and straight-way strainers which are carefully designed to give favourable ﬂow conditions.

The design makes the strainer easy to install, and ensures quick strainer inspection and cleaning.

FIA SS strainers are used ahead of automatic controls, pumps, compressors etc., for initial plant start-up and where permanent ﬁltration of the refrigerant is required. The strainer reduces the risk of undesirable system breakdowns and reduces wear and tear on plant components.

• Applicable to HCFC, HFC, R717 (Ammonia), R744 (CO2) and all ﬂammable refrigerants.

• Designed to give favourable ﬂow conditions.

• Housing is made of special cold resistant stainless steel approved for low temperature operations.

• Easy to disassemble for inspection and service.

• Butt-weld DIN and ANSI connections.

• Max. operating pressure: 52 bar g / 754 psig

• Tem perature range:

-60 – 150 °C / -76 – 302 °F.

• Compact and light valves for easy handling and installation.

• Classiﬁcation: DNV, CRN, BV, EAC etc. To get an updated list of certiﬁcation on the products please contact your local Danfoss Sales Company.

Pressure Equipment Directive (PED)

FIA SS strainers are approved in accordance with the European standard speciﬁed in the Pressure Equipment Directive and are CE marked. For further details / restrictions - see Installation Instruction.

Installation / Maintenance

The strainer is designed to resist high internal pressures. However, the piping system in general should be designed to avoid liquid traps and reduce the risk of hydraulic pressure caused by thermal expansion.

Danfoss recommends replacement/cleaning of the strainer when the diﬀerential pressure loss >0.5 bar / 7.3 psi in the liquid line and >0.05 bar /

0.7 psi in the suction line. The max. permissible diﬀerential pressure is 1 bar / 15 psi.

Pressure regulating valves OFV-SS

Features OFV-SS

OFV-SS are angle-way over ﬂow valves, which have ajustable opening pressure and cover the diﬀerential pressure range (∆P): 2 – 8 bar / 29 – 116 psi. The valve can be closed manually, e.g. during plant service and have backseating, enabling the spindle seal to be replaced with the valve still under pressure.

The valves are especially designed to prevent ﬂuttering due to low velocity and/or low density. In consequence it is possible to apply the valves with wide ﬂuctuations in capacity demands, i.e. from maximum performance to part load. A ﬂexible O-ring provides perfect sealing over the seat.

• Applicable to HCFC, HFC, R717(Ammonia) and R744 (CO2).

• Full temperature range packing gland

-50 – 150 °C / -58 – 302 °F

• Maximum operating pressure 52 bar / 754 psi g

• Three functions in one valve. The OFV valve combines the functions of an overﬂow valve, a check valve and a stop valve

• Low temperature stainless steel housing and bonnet

• Low temperature packing gland

-60 – 150 °C / -76 – 302 °F

• Classiﬁcation: DNV, CRN, BV, EAC etc. To get an updated list of certiﬁcation on the products please contact your local Danfoss Sales Company.

EVRS / EVRST 10 and 15

The solenoid valve design is based on three diﬀerent principles:

1. Direct operation

2. Servo operation

3. Forced servo operation

1. Direct operation

EVRS 3 is directly operated. The valve opens direct for full ﬂow when the armature (16) moves up into the magnetic ﬁeld of the coil. This means that the valve operates with a min. diﬀerential pressure of 0 bar. The valve plate (18) made of teﬂon and is ﬁtted direct to the armature (16). Inlet pressure acts from above on the armature and with it the valve plate. Thus, inlet pressure, spring force and the weight of the armature act to close the valve when the coil is currentless.

EVRST EVRS

EVRS / EVRST 20

When current is applied to the coil the armature is drawn up into the magnetic ﬁeld and opens the pilot oriﬁce. This relieves the pressure above the diaphragm because the space above the diaphragm becomes connected to the outlet side of the valve. The diﬀerential pressure between inlet and outlet sides then presses the diaphragm away from the main oriﬁce which opens to full ﬂow. Thus a certain minimum diﬀerential pressure is necessary to open the valve and keep it open. For EVRS 10, 15 and 20 valves this diﬀerential pressure is 0.05 bar. When current is switched oﬀ, the pilot oriﬁce closes. Then the pressure above the diaphragm rises, via the equalization holes (73) in the diaphragm, to the inlet pressure and causes the diaphragm to close the main oriﬁce.

2. Servo operation

EVRS 10, 15 and 20 are servo operated with a "ﬂoating" diaphragm (80). The pilot oriﬁce (29), which is of stainless steel, is placed in the centre of the diaphragm. The teﬂon pilot valve plate (18) is ﬁtted direct to the armature (16). With the coil currentless, the main oriﬁce and pilot oriﬁce are closed. The pilot oriﬁce and main oriﬁce are held closed by the weight of the armature, the armature spring force and the diﬀerential pressure between inlet and outlet sides.

3. Forced servo operation

EVRST 10, 15 and 20 are forced servo operated solenoid valves. Forced servo operation diﬀers from servo operation in that in a forced servo operated valve the armature and the diaphragm are connected by a spring. Thus the armature helps to lift the diaphragm (80) and keep it lifted so that the pressure drop in the open valve is the least possible. These types of valves therefore require no diﬀerential pressure to keep them open.
