Product Description

Triple eccentric pneumatic multilayer hard sealing Check Valve

Triple eccentric pneumatic multilayer hard sealing check valve is suitable pipeline systems of steam or micro dust media with temperature less than 425℃ to avoid medium backflow and protect fan & pipeline, etc.

The Cast iron pneumatic high temperature butterfly check valve is mainly composed of valve, valve shaft, butterfly plate, oil control device, cylinder type Pneumatic Actuator, transmission mechanism, butterfly plate opening degree adjustment mechanism, butterfly plate opening and closing state electrical signal device and other parts. The Oil control device to achieve the buffer function; Pneumatic actuator to achieve the function of forced off the butterfly plate; butterfly plate opening degree adjustment mechanism to control the opening degree of the butterfly plate to achieve precise control; The electric signal device to display Whether the butterfly disc is on or off.


1 Disc can automatically be closed or opened under the medium pressure, with the functions of power-assist buffering and disc forced closing
2 Cylinder ensure valve quick forced closing.
3 Disc opening degree adjust device control opening degree precisely.
4 Valve is assembled with electric signal device to display disc open or close.
5 Triple offset structure will lower sealing surface abrasion, with long service life & zero leakage.
6 New structure and reliable operating.
