Imported Pneumatic Wafer Butterfly Valves (Imported Pneumatic Midline Butterfly Valves, Imported Pneumatic Riserless Butterfly Valves, Imported Pneumatic Soft Seated Butterfly Valves)

Brand: German VordWODE

Imported pneumatic butterfly valves are designed to operate under certain pressure (usually less than)0.8MPaThe air is converted into rotational motion through the reciprocating movement of the piston within the cylinder, thereby actuating the butterfly valve's opening and closing. The valve consists of the cylinder, a mechanical actuator, and the butterfly valve body. When in use, the user should install an electromagnetic directional valve, air filter, oil mist eliminator, throttle valve, and pressure-reducing valve, among other pneumatic accessories, in the air supply pipeline. Through the control roomPLCControl system for easy centralized and remote automation of valve operations, significantly enhancing production efficiency.

Product Features

Axle plate with non-detachable connection, compact structure, light torque, easy installation and maintenance.

Powered by compressed air, the cylinder achieves rapid control of the valve through an electromagnetic directional valve, providing quick opening and closing, high efficiency, and energy saving, especially suitable for explosion-proof requirements.

Soft-sealed,90° Open/close, zero leakage, long service life

Utilizing an intelligent locator, receiving4-20mACurrent signal, capable of automatically achieving excellent valve regulating performance

Utilizing a valve position feedback device, providing a passive contact signal corresponding to the valve's position.

In response to specific operational conditions, such as sudden power or gas outages, we can provide normally closed or normally open pneumatic valves, and also configure manual operation mechanisms for manual operation.

Selecting various component materials, suitable for a wide range of media.

Surface epoxy resin coating, corrosion-resistant and aesthetically pleasing

Application Scope:

Imported pneumatic butterfly valves are suitable for temperatures ≤120° C or ≤150°C, Nominal Pressure ≤2.5MPaSanitary and stormwater systems, food processing, heating, gas, shipbuilding, hydropower, metallurgy, energy systems, and light industry and textiles sectors, particularly suitable for double-sealed and easily corroded valve bodies, used for regulating flow and intercepting media.
