Description
The rotary disc valve is designed for use as a shut-off or control valve for flow control in heat supply systems, water supply, in technological processes in the food, chemical, oil and gas, pulp and paper and other industries.
Operating principle: The valves open and close by turning the disk by 90°. Opening is done by turning the handle counterclockwise, closing - clockwise.
Limit switches are designed to monitor the position of the disk of rotary disc valves with a handle in control and automation systems. The operating principle of the limit switch is based on mechanical action on the actuator, which results in closing or opening of the electrical circuit.
