What is the difference between single action and double action of the sandwich type hard seal butterfly valve

The split effect and dual effect of the clamp -type dilute butterfly valve are used. For the piston structure of the clamp -type hard -seal butterfly valve, the powerful torque increases, flexible rotation, simple structure, small size and light weight, and other advantages. The valve body adopts several forms of (mid -line, or three -pointed metal sealing, tetrafluoro seal, and dual -eccentric soft sealing). For cases where the clamp -type hard sealing butterfly valve can be used on the scene where the space is narrow and the pipeline distance is shorter. Ring, bolt, etc., reliable work, long service life, can be installed in multiple stations without being affected by the direction of the medium.
The sandwiches are widely used in chemical, building materials, power stations, glass and other industries in chemical, cold air or heat gaseous pipelines in industries such as chemical industry, building materials, power stations, and glass.

The main features of the clamp -type dilute butterfly valve:

1. The design is novel, reasonable, unique in structure, light weight, and rapid opening.

2. The sealing part can be replaced, and the sealing performance is reliable to reach the two -way seal zero leakage.

3. The characteristics of sealing materials are resistant to aging, corrosion resistance, and long service life.

4. There is no sales connection between the two -section valve stem, the structure is simple and compact, and the maintenance is convenient.

5. Valve seat sealing and back -back structure to reduce the deformation of the valve seat.

6. Valve stem axis positioning device to enhance sealing and reduce valve torque.

7, can be installed at any location, easy to repair.
