Viral Water Butterfly Valve Elephant Wbv1631n-2w-fb-h, Body Material - Cast Iron Qt450, Disk Material - Stainless Steel Aisi 304, Seal - Nbr, With Pneumatic Actuator Double Action Pa-da, Electropneumatic Rotary Positioner Yt-1000rsn Without Feedback Now On Sale [rmN2lcAB]

Butterfly valves are designed for use as shut-off or regulating valves for controlling flows in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries. The valves are opened and closed by turning the disk by 90°. Opening is performed by turning the handle counterclockwise, closing - clockwise.

PA-DA double-acting pneumatic rotary actuators are designed to automate the process of controlling industrial valves with maximum torque up to 2128 Nm.

The electropneumatic rotary positioner is used to control pneumatic rotary actuators using an electric controller or control system with a 4 to 20 mA analog DC output signal range.
