High Pressure

Welcome to the world of “innovative valve technology”

GSR is a German manufacturer of standard and specially designed valves and valve systems, with solenoid, pneumatic and electric motor actuators, for nearly all types of industry and applications.

The range includes Solenoid Valves, Pressure Controlled Valves, Motorised Valves and valves specially designed for High Pressure applications.

  • Pressure: Up to 400 Bar
  • Temperature: - 40 to + 350 degrees C
  • Size: Up to DN300

Valves are available Normally Open or Normally Closed and may be supplied complete with a wide range of options including, Manual Override, Anti-Hammer, Limit Switches, Parabolic Plugs, 4 - 20 mA / 0 - 10V Input Controllers, 3-Position Pneumatic Actuators, and many more.

GSR is particularly competent in the area of valves for High Pressure applications and the following are only a small selection of their extensive range of High Pressure valves.

GSR Type 46: This 2/2 way solenoid valve has a stainless steel body, is available in sizes from G1/4” to G1-1/2” and can control liquids and gases from 1 to 150 bar.

GSR Type 52: This 2/2 way solenoid valve is available Normally Opened or Normally Closed, with brass or stainless steel body, in sizes from G1/8” to G1/2” and can control liquids and gases from 0 to 350 bar. This valve is direct acting and a pressure differential is not required for operation. Type 52 is available with manual override and may be manifold mounted if required. This valve is available with ‘Germanischer Lloyd’ approval Certificate.

GSR Type 1/921: This 3/2 way direct acting, pressure controlled slide valve is available with a universal function and is therefore suitable for the distribution of two media, for mixing, or simply as a pilot operated shut-off valve. Applications include both water and oil hydraulics from 0 to 450 bar. Available in sizes from G1/8” to G1” with a seat diameter of 10 and 22 mm. Seals are PTFE and body materials are brass or stainless steel.

GSR Type 2/529 : is a 2/2 way pilot operated piston valve for the supply of high pressure components. This valve has been especially developed for natural gas and hydrogen filling stations and is capable of handling pressures from 1 to 450 bar. Available with connection sizes G1/4” to G2” and with seat diameters from 6 to 50 mm. Seals options are PTFE, TECAPEEK or PCTFE and body material is stainless steel. This valve is also available with explosion proof solenoid.

These are just some of the examples of valves manufactured by GSR specifically for High Pressure applications. Special designs are also available for Paper Processing, High Pressure Chemical Spraying and Fire Extinguishing. Most solenoid versions are available with Explosion Proof Coils.
