ZEG type valves

Solenoid valve ZEG

• 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)
