Full Internal Pressure - Relief Valves

Full Internal Relief Valves are designed for use as primary pressure relief valves in NH3 & LPG transport trailer and bobtail installation containers. As the name implies, all valve components are internal (to the container connection), thereby preventing damage in case of roll-over.

Key Features:

• Durable stainless steel body construction
• Available with Viton®, Nitrile, or Kalrez® valve seals
• Available with 265 & 250 PSI set pressures
• Large seating surface for superior seal performance & reliability
• Maximum corrosion resistance as all the components are placed internally
