Are you going to buy pneumatic flanged butterfly valve from China ? Welcome your inquiry to Decho . Decho can supply you a 7 days fast delivery days.
Pneumatic flanged butterfly valve can achieve good sealing, low disc valve sealing materials have nitrile butadiene rubber, fluorine rubber, rubber, four fluorine lining so sealed performance is good, the butterfly valve is not only in the oil, gas, chemical industry, water treatment and other general industrial used widely, but also applied to the cooling water system of thermal power plants
Connecting flange: EN 1092 PN 6/10/16 ASME Class 150 AS 4087 PN 16
Sealing surface of flange: EN 1092 Form A /B ASME RF, FF
Operating temperature:- 20 ~ 120 ℃
Working pressure: Max 16 bar/ 150LB
Product features:
1. The fluid resistance is small, and the effective circulation area is large when the pneumatic disc valve is fully open.
2. The opening and closing are quick and easy, and the disc is rotated 90 angles to complete the opening and closing.
3. Due to the proximity of the dielectric force of the disc plate on both sides of the rotating shaft, the torque direction is the opposite, so the opening torque is smaller.
4.can achieve good sealing, low disc valve sealing materials have nitrile butadiene rubber, fluorine rubber, rubber, four fluorine lining so sealed performance is good, the butterfly valve is not only in the oil, gas, chemical industry, water treatment and other general industrial used widely, but also applied to the cooling water system of thermal power plants
