DESCRIPTION

Solenoid valves type 21H are normally closed valves, energised to open

and similar in design to servo acting valves 21W series but with the

diaphragm coupled to the solenoid plunger. This enables the valve to

operate at zero pressures without the need for a pressure differential, thus

overcoming the problem associated with gravity feed and circulatory

systems. Operates from zero pressure, no differential required.
