High thermal pressure relief devices (TPRD) up to 60,000 psi

  • It is important for high thermal pressure relief valves to perform at the highest levels with an eye towards safety, costs, and cutting edge technology.
  • With over 75 years of cumulative experience, Precision High Pressure has what it takes to deliver high quality products and exceptional service that will help you get the job done.

Key features

  • Precision High Pressure adjustable relief valves are designed to protect against over pressure of gas and liquids.
  • These proportional relief valves are designed to open gradually as the pressure increases. They do not have a capacity rating at given pressure increases, and therefore these relief valves are not certified to ASME code requirements. This is standard for the high pressure industry.
  • Adjustable field
  • Suitable for gas or liquid
  • Inlet connection – 1/4” FNPT (10RV) and 1/4” HPF (20RV) are standard.


High thermal pressure relief device is made of the following materials:

  • Body – 316SS stainless steel
  • Seat gland/outlet – 316 stainless steel
  • Stem – 17-4PH
  • Seal materials – PTFE packing/EPDM
  • Soft seat – Nylon

Application areas

  • Fuel cells
  • Refilling stations
  • General hydrogen purposes
