一.Product Introduction
The pneumatic hard/soft sealed ball valve is a specialized valve product: its valve seat sealing surface undergoes professional hardening treatment, and the ball body is made of wear-resistant hard alloy. The valve seat adopts a spring loading and scraper structure, which allows it to maintain excellent sealing performance within a wide range of temperature and pressure fluctuations.
This valve can operate stably even under harsh working conditions (such as high temperature, high pressure, wear resistance, and strong corrosion), and is also suitable for scenarios where the medium is relatively sensitive.
二.Product Features
- Equipped with fire protection design and anti-static device, ensuring good safety performance.
- Adopts full-bore design, which has strong flow capacity and low flow resistance.
- The valve seat is designed with an automatic pressure relief structure, which can automatically release pressure when the internal pressure of the valve cavity is too high.
- Multiple sealing structure forms are available for selection, which can adapt to different application requirements.
