Pneumatic cut off the butterfly valve, cut off the butterfly valve, butterfly valve

Pneumatic switch butterfly valve Introduction:

Pneumatic switch butterfly valve (also known as pneumatic cut off butterfly valve) is generally used for cutting off the two switch control of the medium in the industrial pipeline, using the air source pressure to drive the disc to do full open or full open action. According to the form of action, the butterfly valve can be divided into normally open or normally closed, that is, the valve is open or closed in the non-working state, and it can automatically reset to the open or closed state in the case of no air source, power failure or gas path failure. The opening and closing speed of the pneumatic butterfly valve is very fast, especially suitable for quick switching or emergency cutting occasions.

Pneumatic switch butterfly valve Advantages:

1, the pneumatic butterfly valve is simple in structure, easy to install and disassemble, convenient maintenance, and has a wide range of application.

2, two-way sealing function, can be installed in any direction, installation is not affected by the medium flow direction and spatial position.

3, the pneumatic butterfly valve only needs to rotate the disc 90 degrees to complete the switching action, the operating torque is small, labor-saving, and the switching speed is fast.

4, single-acting actuator, can effectively prevent the work of air source break or pipeline failure, automatic spring return to close or open the valve.

5, the pneumatic butterfly valve receives the switching signal of the control system to control the valve switch, so as to achieve tight cutting of the medium in the pipeline.

Pneumatic switch butterfly valve application:

The pneumatic switch butterfly valve is divided into flange type and sandwich type according to the connection method, and is divided into metal seal and soft seal according to the sealing material. It can be applied to a variety of different media, different temperatures and different working conditions. It has strong adaptability, good sealing performance, convenient installation and other advantages. Pneumatic butterfly valve can be widely used in steam, gas, environmental protection, petroleum, chemical, sewage and other industrial pipelines for remote centralized control or local control.
