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.
