How to use

solenoid valves

This booklet has been compiled to help in the installation of compact and high performance solenoid valves and in locating faults in systems with solenoid valves.

The compact range has small physical dimensions for control of ﬂow where space is limited. The high performance range is a sturdy and universal valve program for control of ﬂow in industrial plants and within heating and sanitary systems.

Note that this booklet describes only brass solenoid valves. For other types, please contact Danfoss.

If you need help choosing a solenoid valve, visit the online valve selector at valveselector.danfoss.com

Flexible and user-friendly

Danfoss solenoid valve bodies and electrical coils are normally supplied separately and then combined together. They are assembled quickly and simply without any tools. This provides optimum product ﬂexibility and availability. If a coil needs replacement it can be done without stopping or draining any system.

The solenoid valves are also available as assembled units if required.

Installation

Flow direction

Water hammer

To be able to operate correctly, all solenoid valves must be installed with the arrow cast on the body pointing in the direction of ﬂow.

Water hammer is a typical result of high liquid velocity (high pressure and high ﬂow velocity through small pipe diameters).

There are several reasonable solutions to the problem:

1. Reduce the pressure by installing a pressure reduction valve ahead of the solenoid valve. If possible, increase the pipe diameter.

2. Damp the water hammer by installing a ﬂexible hose or ﬂexible buﬀer ahead of the solenoid valve.

3. Use a solenoid valve of the type EV220B 15 – EV220B 50. The equalizing oriﬁce can be replaced by a version with smaller diameter. This gives a longer closing time (see

Danfoss

“Spare parts” and “Opening and closing times”).

Tightening up

Danfoss

A32U1175.11

The pipes on both sides of the valve must be securely fastened.

When applying test pressure: All valves in the system must be open. There are three ways of doing this:

1. By applying voltage to the coil

2. By opening the valves manually(when the manual override accessory is ﬁtted)

3. By connecting the Danfoss permanent magnet (see "Tools", page 42)

Note that the manual opening unit is not supplied as standard, but as an accessory for EV220B 15 – EV220B 50 valves (see page 33).

Remember to screw the opening unit back (CLOCKWISE) before starting up the system, otherwise the valve cannot close.

Always use counter-force when tightening up pipe connections, i.e. use a spanner on both the valve body as well as on the pipe connector (as shown).

Cable connection

Check to ensure that the coil operating voltage is correct (see text on coil, in “Volt”). Also ensure that the data is correct (voltage and frequency) and matches the supply. If the two sets of data do not correspond, the coil might burn out. As far as possible, always choose single-frequency coils; they give oﬀ less heat than double-frequency versions.

The coil has three pins. The middle pin is marked according to the illustration (left) and must be used for earthing. The two other pins are coil terminals and either can be used for the phase or neutral supply. The terminals can be used respectively for phase and neutral as required.

Please note for high performance range! When mounting the clip-on coil, simply press it gently onto the armature, until it clicks into place. An O-ring should be ﬁtted over the armature tube before ﬁtting the coil.

Cable entries must always be screwed in correctly.

The cable must be installed as shown in the illustration to avoid water running into the terminal box.

Installation

Cable

Coil replacement

To avoid moisture penetrating in the terminal box, the whole cable diameter must be secured in the entry. For this reason, always use round cables as they are the only type that can be eﬀectively sealed.

Note the colours on the cable leads. Yellow/green is always earth. The other leads should be for the phase and neutral supply.

Please note for clip-on coils: When replacing a coil, use a screwdriver to lever it from the armature.

Caution: Before removing a coil, voltage must be disconnec ted, otherwise the coil will burn out.

How to choose

If you do not have internet access try indentify all relevant parameters.

This includes: 1 Capacity / Kv - value 2 Pressure conditions 3 Media conditions 4 Other conditions

Capacity / Kv - value:

1 Speciﬁes how many m3/ hour (capacity) water is passing through the valve at a diﬀerential pressure at 1 bar. 2 Is a result of all the diﬀerent constants coming from shape of oriﬁces, units etc. which are reduced to one new constant, the k 3 Is used to calculate capacity: 4 ρ = density (kg / m 5 ΔP = P

- P

)

Q = Kv

Pressure conditions

Open system (system with drain)

In an open system the pressure conditions are well-deﬁned. This enables clariﬁcation as to whether there is suﬃcient pressure diﬀerential to be able to open a servo-operated valve. The following types of valves are well-suited for use in open systems:

EV210B and EV310B direct-operated solenoid valves EV220B, EV220A and EV225B servo-operated solenoid valves

Closed circuit (circulating system)

In a closed circuit system the pressure conditions are undeﬁned. Therefore a solenoid valve capable of opening without pressure diﬀerential is required.

How to choose

Operating pressure

Valves in the standard range are designed for pressure of max 6–30 bar – the actual ﬁgure depends on the type of valve. The product range includes valves for special application, designed for pressures of up to 80 bar. The large standard range combined with these valves enable the use of Danfoss solenoid valves for all types of systems, wether with normal or more extreme inlet pressures.

Diﬀerential pressure/ MOPD

1 Diﬀerence between inlet pressure and outlet pressure (∆P = P1 - P2). 2 Max. permissible diﬀerential pressure against which the valve can open 3 Also speciﬁed as MOPD: Maximum Opening Pressure Diﬀerential 4 MOPD speciﬁes the diﬀerential pressure value in worst case:

• 100 % duty rate

• Maximum medium and ambient temperature

• Nominel voltage, typically -10% 5 Speciﬁed pressure is often limited by endurance demands more than MOPD

Media conditions

The valves are designed to resist the temperatures normally found in industrial applications.

If the temperature is outside these limits, there is a risk of the valve not functioning correctly because of, for example, rubber materials becoming hard. Exceeding the temperature rating can also result in the shortening of valve life. If the valve is to be used in a special application, with a temperature in excess of the rated limits, there are valves available in the product range which have been designed for use in higher temperature systems.

IC.PS.600.A8.02 | 15

How to choose

The characteristics of the medium

The valves have been designed for use with diﬀerent media.

In general the following is valid: Valves containing EPDM-rubber are suitable for water and steam*. Valves containing FKM-/NBR-rubber are suitable for oil and air.

Incorrect use of valve types: 1 If a valve containing EPDM-rubber is used for a medium containing oil (compressed air

normally contains particles of oil from the compressor) the rubber will expand and the valve will not be able to function optimally.

2 A valve containing FKM-/NBR-rubber can be used for water. However for servo-operated

valves, the water temperature must be kept below 60 °C for FKM, 90 °C for NBR. If this temperature is exceeded it will have a negative eﬀect on the life of the valve.

Other media

For slightly aggressive media (e.g. demineralised water) dezinciﬁcationresistant brass valves must be used. Stainless steel valves are used for more aggressive media.

*For steam temperatures above 120 °C there is a type of valve especially designed for steam

Ambient temperature

The ambient temperature must be within certain limits for the coil to function optimally. See data sheet for coils.

IC.PS.600.A8.02 | 16

How to choose

Water hammer

All piping systems with relatively high ﬂow rates are susceptible to water hammer when a valve is opened or closed. A damped solenoid valve ( eg. EV220B 15–50) should be used if there is a risk of water hammer. After installation the valve can be adjusted for water hammer by changing a replaceable equalizing oriﬁce. See "Spareparts" page 32.

Filter

In systems with contaminated media there is a risk of moving parts in a valve not working as intended. Dirt is the most common cause of function failure in solenoid valves. To help avoid this problem we suggest the ﬁtting of a ﬁlter on the upstream side of the valve.

Coil voltage and power

It is necessary to know which voltage (Volt AC/DC nominel ± 10%) is available within an application to select the correct coil. The maximum permissible diﬀerential pressure can also be increased by ﬁtting a more powerful coil. The coil power depends on the type of coil (BA, BB, AM etc.).

Other environmental factors

In wet or very humid environments, coils with IP67 enclosure classiﬁcation must be used.

Valve function

Most industrial systems operate with a de-energised closed valve (NC = normally closed). Our valve range also oﬀers de-energised open valves (NO = normally open) for applications requiring this feature.

Equalizing oriﬁce

The kit comprises:

An equalizing oriﬁce includes 2 O-rings. The valves closing time can be changed by installing an equalizing oriﬁce of a size which deviates from the standard valve:

• A shorter closing time is obtained with a larger oriﬁce (the shorter closing time, the greater risk of water hammering)

• A longer closing time is obtained with a smaller oriﬁce.
