 High Pressure Check Valves up to 60,000 PSI (414 Mpa) 
High pressure check valve - also named clack valve, non-return valve or one-way valve - allows high pressure liquid or gas to flow through it in only one direction.

High Pressure Check valves are used in many fluid systems such as those in chemical and power plants, and in many other industrial processes when multiple liquids or gases are mixed into one liquid/gas stream. A check valve is installed on each of the individual liquid/gas streams to prevent mixing of the liquids/gases in the original source. For example, if a fuel and an oxidizer are to be mixed, then check valves will normally be used on both the fuel and oxidizer sources to ensure that the original gas cylinders remain pure and therefore nonflammable.

 

FEATURES & BENEFITS
  • Prevents reverse flow where leak-tight shutoff is required
  • Two styles of high pressure check valves to fit most applications:
    Ball Seat Poppet Check Valve - Metal-to-metal seat for rapid cycling or severe environments
    Soft Seat Poppet Check Valve - O-ring seat for fast shut-off and reliable seal; standard material is Nitrile. A variety of seal materials are available for even the harshest media.
