Soft sealing butterfly valve, as a kind of used to implement the pipeline system of cut and flow control components, it is usually used in petroleum, chemical, natural gas, metallurgy, electric power, medicine, such as water supply and drainage, for adjusting flux on the gas pipeline, and the effect of cutting fluid.The sealing material is rubber, polytetrafluoroethylene, etc.My company independent research and development of soft sealing butterfly valve, double eccentric butterfly valve structure, USES the memory characteristics of seal packages can increase the seat ring composite structure, application of flexible sealing technology, eliminates the abrasive wear, plastic deformation, the influence of temperature, pressure, to achieve reliable seal.This valve is compact in structure, light in weight and reliable in sealing.Compared with the traditional valve, it is easy to install, easy to maintain and long service life.It is widely used in the automatic control system of automatic control system.

Technical characteristics

Unique seating structure.

1. Bidirectional elastic seal, two-way zero seal;

2. Change of automatic compensation temperature and pressure;

3. The effective sealing of the seal is relatively large;

4. Long service life and small maintenance.

Double eccentric butterfly plate design.

1. The seat is not in contact with the butterfly plate during the whole opening process.

2. No wear points on the upper and lower seats.

3. Low operating torque.

Seat maintenance is convenient.

1. Replace the seat without removing the butterfly plate and stem.

Cut and control both.

1. Excellent control characteristics.

2. Variation of flow characteristic curve.

3. Wide range of adjustment.

4. For control, it can still be effectively sealed.
