Pressure Relief Valves

  • Prevent System Over-Pressurization
Upchurch Scientific Pressure Relief Valves are ideal for preventing system over-pressurization. These products protect system components by diverting fluid flow automatically when pressure exceeds the set limit. Choose between our preset 100 psi (7 bar) and 5 psi (0.3 bar) assemblies, both shipped with our 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 0.020" (0.50 mm) 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 with the P-612 Pressure Relief Valve Tee. Choose the P-612S for larger bore tubing and higher flow applications.
