Necessary Information On Ultra High Pressure Valves

Understanding high pressure valves is very important for optimum utilization of the valves as well as the safety of the system and the operator. Valves are devices that are used to control the flow of the gas or liquid within a system. Different types of valves are used in the various systems depending upon the temperature, pressure, application and reactive action of the contents with that of the valves. Keeping this in mind, material like brass, stainless steel, plastic, PTFE etc are used to manufacture the valves.

Gases like oxygen, argon, carbon dioxide, nitrogen, helium, hydrogen and welding gas mixtures generate a very high pressure. To prevent any accidents and calamities, the right quality ultra high pressure valves should be used. The valves that are used in high pressure systems usually come with a built-in pressure relief device that provides excellent flow characteristics.

The most reliable ultra high pressure valves are of the GVHM series. The two variants of the GVHM series valves are:

• GVHM Series - Ultra High Pressure Valves – Plated
• GVHM Series - Ultra High Pressure Valves

 

Ultra high pressure valves accommodate ultra high pressure and temperatures. They are used in fitting, tubings or containers that require to contain ultra high pressure. Ultra high pressure valves are used in pumping systems, intensifiers, gas booster, pressure generators,

Construction of GVHM series valves

These ultra high pressure valves can be broken down as follows:

Benefits and key features of GVHM series valves

Every valve of the GVHM series is manufactured by Sherwood at its facility in the USA. Every component is machined for accuracy in assembly which ensures the excellent functioning, durability and safety.

Each valve is 100% helium leak tested

The heavy duty forged brass is used to make the body of the high pressure valves, which offers it durability

The pressure relief device is a unitized plug design that ensures proper assembly, is tamper proof and offers excellent flow characteristics

The metal to metal seal prevents pressure in the pressure in the threads

The direct drive stem design with an optimized double O ring seal reduces the friction and the valve can be operated at extremely low torques

The inlet and outlet threads are configured for a wide spectrum of customers across all countries as per the country code specifications

Tapped for dip tube as required
