Products Design Features

Auto compensation balanced double parallel gate valve is a product with new structure, which has small open-and-close moment, high speed, little vibration,long performance life and reliable operation.lt is mainly applied to cut-off or discharge of gas and liquid delivery pipelines.

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.
