DN20-600

1.6MPa-16MPa

Descriptions

This vaIve owns features of friction resisting structure, reliable seal, excellent anti, wearing ability, dual-way open-close, and easy operation, also can be cleaned with hair-ball through it.

Characteristics & Applications

1. Flat or rounded structure is adopted according to different pressures．

2. The seat has structure of metal ring inlaid with FTFE, which ensures the 

seal ability of soft and then hard The disc adopts stainless steel or carbon 

3. steel material, and its surface is treated with MOSZ．

4. Piston effect of floating seat leads to dual-way seal for inlet outlet of the valve．

The Structural Features Include

1. A sealing structure consists of two parallel shutters and a wedge-tightening device it is taken to replace the traditional wedg eshaped gate valve structure;

2. The components of valve sealing mechanism are separated so the sealing can retain when transmuting caused by the tem perature changes,and will not jam where swelling in high temperature;

3. The sealing surface of the valve adopts abrasion-resistant and anti-corrosive materials which can lengthen the performance life of the valve;

4. In high temperature or pressure,the disc on inlet side can be designed in pressure relief style which can avoid abnormal pressure rising in cavity caused by temperature changes.thus to ensure used safety.

5. The valve adopts full-shut structure which has good protection function and can be used in all weather.
