Soft-sealed Pneumatic Butterfly Valve

Highlight: Soft-sealed Pneumatic Butterfly Valve


Product introduction:


Soft-sealed butterfly valves, as components used to achieve on-off control and flow regulation in pipeline systems, have been widely applied in numerous fields such as petroleum, chemical, metallurgy, hydropower, etc. In existing butterfly valve technologies, most sealing types adopt structural designs with sealing materials like rubber and polytetrafluoroethylene. Due to structural limitations, they are unsuitable for industries requiring high-temperature resistance, high-pressure resistance, corrosion resistance, and wear resistance.
A relatively advanced type is the triple-eccentric metal hard-sealed butterfly valve, where the valve body and seat are integrated components. The sealing surface of the valve seat is overlaid with temperature-resistant and corrosion-resistant alloy materials through surfacing welding. Multi-layer soft stacked sealing rings are fixed on the valve disc. Compared with traditional butterfly valves, this type offers advantages such as high-temperature resistance, lightweight operation, frictionless opening/closing, sealing compensation through increased torque of the transmission mechanism during closure, improved sealing performance, and extended service life.

Product features:


1. Double-eccentric design with dynamic self-tightening seal: Sealing pressure increases as the valve closes, ensuring

reliability under high-pressure and high-velocity media.

2. Stainless steel combined with nitrile oil-resistant rubber for sealing: High-strength, corrosion-resistant, oil-resistant,

anti-aging, and long-lasting.

3. Rubber sealing ring can be installed on the valve body or disc, adapting to different media characteristics for versatile

applications.

4. Frame-structured disc balances strength and lightness: Large flow passage reduces resistance, saves energy, and

enhances flow efficiency.

5. Overall baked enamel coating for corrosion protection; quick-change sealing seat enables easy adaptation to various

media.

6. Bidirectional sealing allows installation without restrictions on flow direction or orientation, ideal for flexible installation in

complex pipe networks.

7. Ergonomic mechanical design reduces operating torque by over 30%, ensuring precise and smooth operation for both manual and automated control, with high maintenance efficiency.
