Two-way Metal Seal Butterfly Valve

Two-way metal seal butterfly valve

[Butterfly valve] is widely used in: chemical industry, petrochemical, petroleum, papermaking, mining, electric power, liquefied gas, food, pharmaceuticals, water supply and drainage, municipal administration, mechanical equipment supporting, electronic industry, urban construction and other fields.

Application scope of two-way butterfly valve:

Double eccentric two-way metal seal butterfly valves are widely used in water conservancy projects, tap water, power circulating water, petroleum, chemical and other industrial pipelines to cut off the flow of media.

Structural features of two-way metal seal butterfly valve:
1. The butterfly valve is a two-way pressure-bearing, two-way metal seal. The special structure can adjust the sealing pressure ratio arbitrarily. It adopts an eccentric S-shaped conical valve seat sealing surface, which makes the sealing surface less likely to be damaged and improves the service life of the valve.
2. The operating torque is small, and it can be opened and closed by turning 90 degrees, which is light and fast.
3. The flow resistance is small, and it has good hydraulic characteristics. The flow characteristics are similar to an inclined straight line, and the energy saving effect is good. The two-way seal has no direction requirement for the water flow.
4. The sealing is reliable and the opening and closing life span is more than 20,000 times.
5. The valve plate adopts a double-plate truss-type multi-channel design that conforms to fluid mechanics properties.
