DESCRIPTION

Solenoid valves Type 21IH are normally closed valves, energised to open

and similar in design to servo-acting valves but with the diaphragm coupled

to the solenoid plunger, This enables the valve to operate at zero pressure

and without the need for a pressure differential, thus overcoming the

problems associated with gravity feed systems.
