	PNEUMATIC VALVES (WEIR AND STRAIGHT THROUGH)

rPressure across the valve

Actuated / Pneumatic Valves:

Also known as Auto diaphragm valves - Pneumatically operated diaphragm actuators can be direct, reverse or double acting in operation with spring or can be springless. Springless actuator can be supplied with the air reservoir for fail safe position.

Salient Features:

Diaphragm Actuators Sizes:
Effective area 9 sq. in. to 300 sq. in. and in case of double
diaphragm actuators. it can go up to 600 sq.in.to match any thrust requirements

Control Valve Closing time:
Approximately 8 seconds

Control Valve Opening time:
Approximately 20 seconds

Operating Air Pressure:
Upto 50 psig for diaphragm
Upto 100 psig for Cyclinder
Springless type actuator can be supplied with 3 psig constant loading

Operating Line pressure:
150 psig for valve size up to 100mm
120 psig for valve size upto 150mm
Above 150 mm size, line pressure will be lower.

Direct acting actuated diaphragm valve (Air to close, spring to open, DOPC):

This actuator is designed to operate from a normally open position. Air pressure on
the top side of the actuator diaphragm closes the valve, and the spring opens the
valve, when the air is released from the actuator. (Air failure valve opens)
