Pressure Relief Valves

• Prevents system overpressurization
• 5 psi or 100 psi versions
• Assemblies and Tees include Flangeless Fittings

Our Pressure Relief Valves are ideal for preventing system overpressurization. They are designed to protect system components even if flow is blocked while the pump is on.

Choose between our preset 100 psi (7 bar) and 5 psi (0.3 bar) assemblies, both of which come complete with Upchurch Scientific® Flangeless Fittings. The 100 psi version is a good, general purpose valve, while the 5 psi version is perfect for protecting syringe and peristaltic pump systems. The void volume of both relief valves is low, due to the small .020” (.50mm) thru-holes in the valve tee body.

If you wish to have the Pressure Relief Valve open at a different pressure than 5 or 100 psi, simply combine one of the other replacement Back Pressure Regulator Assemblies listed in "Alternate Parts" with the P-612 Pressure Relief Valve Tee. Choose the P-612S for larger bore tubing and higher flow applications.
