Project Description
Solenoid valve ZEPW
2/2 NC- membrane, assisted lift
- suited to zero pressure differential conditions (ΔPMIN= 0 bar)
- performed with different versions of seals
- in control rooms for two-position gas or liquid flow control
- in pneumatic and hydraulic control systems
- in water circuits (cold and hot), heating systems
- must not be used for gaseous fuels (methane, propane-butane)

* – maxiumum width of valve
** – 42mm for valve without coil
- suited to applications where pressure differential ΔP fluctuates or is very hard to define
- they work properly regardless of the differential pressure ΔP on the valve – although they use process pressures for operation
- they can be used from zero to the maximum PMAX operating pressure on which they have been designed
- have relatively high flow resistance (low Kv) – design considerations
- are sensitive to contamination – proper purity of the medium fluid should be ensured (filters application)
- long actuation times – low connecting frequency
- lifespan – less than for direct acting valves (several hundred of thousand work cycles)
