Features

Pressure seal gate valves enhance the service life and performance of the valve by implementing a flow channel with reduced flow resistance coefficient and energy loss. This unobstructed flow channel significantly decreases the flow resistance and improves the efficiency of the valve operation.

The valve's center cavity is designed with a sealing mechanism that automatically increases seal pressure as the cavity pressure rises, effectively preventing any leaks.

The valve disc and valve seat's sealing surface boasts excellent qualities, thanks to its Stellite cobalt-based hard alloy surfacing. This alloy is renowned for its high resistance to wear and tear, making it ideal for use in valves exposed to high temperatures and harsh environments. Moreover, it's also highly resistant to corrosion and scratches, ensuring that the valve remains fully operational even in the toughest conditions.

After going through the processes of quenching and tempering and surface nitriding, the valve stem now possesses enhanced strength and increased resistance against scratches.

To meet user requirements, the opening and closing parts of a structure can be customized in various forms such as single wedge, double wedge, and parallel double wedge. It's important to note that the design choice is up to the user's preference and needs.

There are valves called bypass valves that are designed to address the problems of over pressurization and pressure locking. These valves serve as a safety measure and help prevent damage to the system by allowing excess pressure to be redirected. With the use of bypass valves, the system can function effectively and efficiently without the risk of compromising safety. These valves are readily available and can be installed as a precautionary measure to ensure the longevity and reliability of the system.
