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.

DESCRIPTION
Pneumatically operated angled seat process valve for the on-off control of
water, steam, air and oil with anti-water hammer technology. Flow direction
below the seat. High flow rate due to the angle seat configuration.
Anti-water hammer feature with fluid entry below the seat. Electrical
operation is easy with the addition of a solenoid pilot. Universal mounting -
any mounting orientation is acceptable. Stainless steel body and corrosion
resistant actuator, and self adjusting internal seals for long life.
