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.
