China Factory for Boiler Swing Check Valve - High performance butterfly valve with pneumatic actuator – GMK Valve
Short Description:
China Factory for Boiler Swing Check Valve - High performance butterfly valve with pneumatic actuator – GMK Valve Detail:
The high performance butterfly valve adopts the design of double-eccentric structure. The shaft carries out double deviation from the structural center of the body and makes the disc leave the sealing seat instantly when it is opened in conjunction with the arc sealing face design of the disc, so as to reduce the friction of the sealing face. The disc has good sealing performance during closing. In addition to realizing effective compensation for the seat seal, the central self-positioning sealing seat structure design and the unique seat compensation sealing design reduce the friction during opening and closing, greatly reduce the operating force of the valve and effectively enhance the control precision of the butterfly valve. The 70E00 Series butterfly valve is featured by stable and reliable sealing performance, long service life, etc. It is suitable for control and shut-off applications of common corrosive gases and liquid media.
