Description

Rotary disc gate valve is designed for use as shut-off or regulating valves for flow control in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
Operating principle: The valves are opened and closed by turning the disc by 90°. Opening is performed by turning the handle anti-clockwise, closing - clockwise.
Elephant pneumatic double-acting rotary actuators PA-DA-XXX and pneumatic rotary actuators with return spring PA-SA-XXX are designed for automation of industrial valve control with maximum torque up to 2128 Nm.
The pneumatic valve is used to change the direction, start, stop the compressed air flow in the pneumatic system depending on the external control action.
