Rising Stem Design of PFA Lined Gate Valve

This valve features a rising stem design that moves the gate upward together with the valve stem during operation. Therefore, users can identify the valve position quickly and operate the system with greater confidence.

Unlike traditional non-rising stem valves, the improved design prevents particles and fibers from collecting around the stem threads. Furthermore, it reduces the risk of blockage and improves operating reliability in demanding process conditions.

Benefits of PFA Lined Gate Valve

The valve body, gate, and stem are fully lined with high-quality PFA material. As a result, the lining provides outstanding corrosion resistance and prevents damage caused by aggressive chemical media.

The PFA lining remains firmly bonded to the valve components and resists collapse under vacuum conditions. Moreover, the TFM seats deliver reliable sealing performance while minimizing leakage during operation.

Compared with high-alloy metal valves, this valve offers a more economical solution with lower weight and reduced operating torque. In addition, the full-port design provides high flow capacity without restricting the process medium.

The valve delivers bubble-tight sealing in both flow directions and supports easy actuator automation. Therefore, it is suitable for manual, pneumatic, and electric operation in modern industrial systems.

Applications

This valve is widely used in industries that require excellent corrosion resistance and dependable shut-off performance. It performs efficiently in chemical processing, petroleum, pharmaceuticals, food processing, metallurgy, pulp and paper, hydropower, water treatment, and environmental protection applications.

Furthermore, it is suitable for handling acids, alkalis, solvents, and other highly corrosive media. As a result, it helps improve production efficiency while reducing maintenance costs.
