pneumatic butterfly valve:
Pneumatic actuator: It use new-style AT pneumatic actuator, with double acting and spring return types driven by gear and rack with high performance, big diameter valves are driven by AW pneumatic actuator on pull-extraction manner, with reasonable structure and large output torque as well as double acting and spring return types.
Center-line Resilient seal: use rubber and fluorine plastic of full liner rubber and fluorine plastic as sealing material. Elastic seat is furnished with high precision butterfly plate to insure zero leakage. Bushings are mounted on the bottom, middle and upper parts of valve stem for supporting and rotary slippage, thus to retain minimum friction. The products are light weighted small sized and quick to open and close.
Triple-eccentricity structure seal: using metal and fluorine plastic for seat sealing. Metal sealed butterfly valves incorporate seat with elastic sealing ring and multilayer composite butterfly plate. Triple-eccentric sealing structure functions small friction upon open and close, dependable seal, anti-friction, high temperature resistance, self-centering effect, little leakage and ling life-span. Provided with the advantages of reasonable structure, lightweight, small sie, dapper installation dimension, easy operation and quick on and off, the fluid control vales have been rapidly developed and most widely used.
