4 Inch 3 Inch Pneumatic Clamp Butterfly Valve Stainless Steel Body

3. Features:

• Main advantages of butterfly valve, simple structure, small size, light weight, low cost, the characteristics of the pneumatic disc valve is especially significant, installed in the high-altitude tunnel, through the two five-way solenoid valve control operation is convenient, but also can adjust the flow medium.
• Small fluid resistance, large diameter pneumatic disc valve fully open when the effective flow area is large, fast and easy to open and close, the disc can be rotated 90 Angle to complete the opening and closing,
• Because the medium force on both sides of the rotating shaft plate hand is close to equal, and the torque generated in the opposite direction, so the opening and closing torque is small, low pressure can achieve a good seal,
• Disc valve sealing materials are butadiene rubber, fluorine rubber, Edible rubber, lined with tetrafluoroethylene, so the sealing performance is good, in which the hard seal disc valve.
• Hard laminated metal sheet with metal hard seal and elastic seal heavy advantages, regardless of low temperature conditions have excellent sealing performance.
