Small Fluid Resistance Hard Sealed Pneumatic Actuator Operated Butterfly Valve

3. Features:

• Small fluid resistance, large effective flow area when the large diameter pneumatic disc valve is fully opened, opening and closing quickly and labor saving, the disc can be rotated 90 angles to complete the opening and closing,
• Because the medium force of the disc hand on both sides of the rotating shaft is close to equal, and the torque generated is opposite, so the opening and closing torque is small, and a good seal can be achieved under low pressure.
• Sealing materials of the disc valve are diacene rubber , fluororubber , food With rubber, lined with tetrafluoroethylene, the sealing performance is good, and the hard seal disc valve is a soft and hard laminated metal sheet with the heavy advantages of metal hard seal and elastic seal, and has excellent sealing performance at low temperature.
