Butterfly Valve Series Valve Manufacturer

Product introduction

The pneumatic butterfly valve is opened and closed with the circular butterfly plate rotating with the valve, in order to achieve the use of the pneumatic valve is mainly used as a cut-off valve, and it can also be designed to have the function of regulating or segment valve and regulating. The butterfly valve is used more and more in low pressure large and medium diameter pipelines.

Product characteristics

1.The main structure of explosion-proof pneumatic butterfly valve is connected by pneumatic actuators and valves, installation of explosion-proof electromagnetic directional valve, voltage AC220V or AC380V, connected to 5kgf/cm² pressure of the air source can be controlled valve, suitable for flammable and explosive occasions.

2.The valve adopts the medium linear structure without eccentric design, has the characteristic of low operating torque, and the economy is significant when the electric device is configured. Using rubber lined structure, the circular sealing surface of the butterfly plate is precision machined to a higher finish, the friction coefficient of the rubber seat is very low, and the valve life is long; The flow characteristics of the sealing surface of the valve plate are linear, and the flow resistance coefficient of the valve is small. The unique design of the molded rubber seat has excellent balance and support, effectively avoiding the damage to the rubber caused by uneven force. When the valve is fully closed, the rubber is in the best compression state to maintain zero leakage.

3.The outer and inner surfaces of the valve shell can be coated with epoxy resin powder by high-temperature electrostatic spraying. The coating has high corrosion resistance, and has high bonding strength with the ductile iron matrix. The coating degree is 0.2-0.5mm.
