Data Sheet

Hand operated regulating valve Type REG-SA and REG-SB 65

Designed for regulation purposes in liquid and expansion lines, suitable for MWP up to 65 bar

REG-SA and REG-SB are angleway and straightway hand regulating valves, which act as normal stop valves in closed position.

The valves are available in two dierent versions – REG-SA and REG-SB designed for regulation purposes in liquid and expansion lines.

The valves are designed to meet the strict quality requirements on refrigerating/heat pump installations specied by the international classication societies and are carefully designed to present favourable ow conditions and accurate linear characteristics.

REG-SA and REG-SB are equipped with vented cap and internal backseating enables replacement of the spindle seal whilst the valve is active, i.e. under pressure.

Hand operated regulating valve, type REG-SA and REG-SB 65

Features

• Modular Concept:

◦ Each valve housing is available with DIN and ANSI butt weld connection and in several dierent sizes. ◦ Possible to convert REG-SA or REG-SB to any other product in the FlexlineTM SVL family (shut-o valve, check &

stop valve, check valve or strainer) just by replacing the complete top part.

• Fast and easy valve overhaul service. It is easy to replace the top part and no welding is needed.

• Designed to ensure perfect regulation

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

• Easy to disassemble for inspection and possible repair.

• Acts as a normal stop valve in closed position.

• Housing and bonnet material is low temperature steel according to requirements of the Pressure Equipment Directive and other international classication authorities.

• Exact capacity and setting of the valve can be calculated for all refrigerants by means of Coolselector™.

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

• Equipped with 42CrMo5 bolts to withstand high pressure.

• Service kits with replacement O-rings for R717 Heat Pump and R1270 Propylene include separate ID-ring for ID of application

Refrigerants

Applicable to HCFC, HFC, R717 (Ammonia), R744 (CO₂) and ammable refrigerants.

For further information refer to the product instruction for REG-SA and REG-SB.

New refrigerants

Danfoss products are continually evaluated for use with new refrigerants depending on market requirements.

When a refrigerant is approved for use by Danfoss, it is added to the relevant portfolio, and the R number of the refrigerant (e.g. R513A) will be added to the technical data of the code number. Therefore, products for specic refrigerants are best checked at store.danfoss.com/en/, or by contacting your local Danfoss representative.

Hand operated regulating valve, type REG-SA and REG-SB 65

The cone

The valves are available in two dierent versions – REG-SA with an A cone and REGSB 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

The spindle is made of polished stainless steel, which is ideal for O-ring sealing.

Packing gland - REG-SA and REG-SB

The “full temperature range” packing gland ensures perfect tightness in the whole range: -60 °C /+150 °C (-76 °F / +302 °F). The packing glands are equipped with a scraper ring to prevent penetration of dirt and ice.

Installation

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

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 product instruction for REG-SA and REG-SB.

Figure 5: Example of marking ring, REG-SA

ID ring for special application

After converting a REG-SA/SB (DN 10-40) valve for Heat Pump/Propylene applications (replacing O-ring) the color marked ID tag included in the service kit must be xed to the valve as shown in gure to the right.

The ID tag indicates the special application and identies the installed O-ring.

Computation and selection

In refrigeration plants, regulating valves are primarily used in liquid lines in order to regulate the ow of refrigerant. The valves can, however, also be used as expansion valves. From a calculation point of view the two elds of application are very dierent.

Normal ow is the term used to describe the general case where the ow 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).

This relationship between mass ow, pressure drop and density satises the majority of all valve applications with refrigerants and brines.

Normal ow is characterised by turbulent ow 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 ow area will reduce the capacity of the valve considerably. In such cases it is recommended to use Coolselector®2.

Figure 7: Location of valve in system (marked with grey)

Sizing regulating valve for liquid ow

Liquid refrigerants: Use the liquid tables, Figure 13: REG-SA 25-40 and REG-SB 25-40, Figure 14: REG-SB 50, Figure 15:

REG-SA 15-20 and REG-SB 15-20

Hand operated regulating valve, type REG-SA and REG-SB 65

Computation and selection Example 1

Refrigerant: R 717 Refrigerant ow: 2200 kg/h Pressure drop: Δp = 0.5 bar

The above mentioned example is illustrated on the following ow rate diagram and shows that REG-SB 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 ash gas in the valve.

Figure 17: Flow rate diagram

Computation and selection Example 2

Brine, density ρ: 1150 [kg/m3] Brine ow G: 2,700 [kg/h] Pressure drop Δp: 0.5 [bar]

In this example it is not possible to use the selection diagrams (Figure 12: REG-SA 15-20 and REG-SB 15-20, Figure

13: REG-SA 25-40 and REG-SB 25-40, Figure 14: REG-SB 50, Figure 15: REG-SB 65) as the refrigerant in question is not

included.

Use the curves of the kv-values instead (Figure 8: REG-SA 15-20 and REG-SB 15-20, Figure 9: REG-SA 25-40 and REG-

SB 25-40, Figure 10: REG-SB 50, Figure 11: REG-SB 65) 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 (Figure 18: Calculation factor CA) and the ow rate diagram (in this example: Figure 19: Flow rate

diagram) as per the following calculation example.

Required kv-value CA = 0.00132 (from Figure 18: Calculation factor CA)
