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. The peculiarity of the gate valves of this series is the complete covering of the flow part and disc with PTFE material, which makes it possible to exclude the contact of the working medium with the materials of the main parts.
DNOVA pneumatic double-acting rotary actuators PA-DA and pneumatic rotary actuators with return spring PA-SA are designed for automation of industrial valve control process 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.
A distinctive feature of this series of valves is that the flow path and disc are completely coated with PTFE, which prevents the working medium from coming into contact with the materials of the main components.
