Rubber lined butterfly valve with pneumatic actuator
Short Description:
Single acting or double acting
with emergency handwheel. Can be with ASCO solenoid Valve,SIMENS Positioner,ABB positioner,YTC positioner,Fisher positioner,Mesto Positioner,SMC filter,APL limit switch ect
The rubber lined butterfly valve adopts the central line cavity rubber lined structure. The body and disc are lined with synthetic rubber or the body is lined with rubber,like EPDM,NBR,Hypalon ect, and the disc is made of high quality alloy steel,Stainless steel,UB6 904l ect so as to effectively avoid the corrosion of the valve by media. It has good sealing performance. The butterfly valve is widely used as an ideal solution to control and shut-off applications of water, air, petroleum, etc.
