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.
