Project Description
Solenoid valve ZEG
- 2/2 NO cl.B
- membrane, assisted lift
- suited to zero pressure differential conditions (ΔPMIN= 0 bar)
- conforms to PN-EN161
- • designed for reliable service in all types of installations and appliances (e.g burners, heating boilers), supplied from low pressure gas network
• as a part of the gas train supplying gas appliances (mentioned above), the valve will act as an automatic safety shut-off valve
• in air conditioning systems
• pneumatic control systems

- 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)
