R - 71700 series high performance butterfly pneumatic valve

R - Series high-performance butterfly pneumatic valve adopts double eccentric structure design. Shaft center double deviating from the aerodynamic body design, and combining with the design of the pneumatic valve plate arc seal face, pneumatic valve plate in open quickly out of the seal seat to reduce the sealing surface friction, pneumatic valve plate in closing has better sealing performance. Center since the positioning pneumatic sealing seat structure design combined with pneumatic compensation seating is uniquely, compensation of the pneumatic valve seat wear effectively, and reduce the friction when the seal pneumatic valve, operating force greatly reduce effectively improve the butterfly pneumatic valve control accuracy. This series of pneumatic valve seal butterfly long life sealing performance excellence is generally applied dry adjust and cut off the use of corrosive gas liquid medium. http://www。 zgbfw。 Com/info /
