Pneumatic Vent Butterfly Valve
Pneumatic Vent Butterfly Valve Introduction
Pneumatic vent butterfly valve, made of steel plate through welding, has the advantages of small size, light weight, convenient utilization. For small torque, it is easy to open or close the valve. The body has oil seal retainer. There is large expansion clearance between the disc and body, which can avoid sticking caused by thermal expansion and contraction.
The Pneumatic vent butterfly valve can be equipped with varieties of actuating devices, such as handwheel, gearbox, electric actuator and pneumatic actuator. This pneumatic vent butterfly valve is widely used in metallurgy, petroleum and other industries, to regulate gas.
