Conbraco Industries 18C-402-37 3/4" Temperature & Pressure Relief Valve 150 PSI

The Conbraco Industries 18C-402-37 Temperature & Pressure Relief Valve releases pressure or heated fluid when operating conditions reach its specified relief threshold. A temperature-sensing element responds to excessive thermal conditions, while the pressure-actuated mechanism opens the discharge path when pressure reaches 150 PSI. The 3/4-inch connection provides the specified installation interface for compatible pressurized equipment. Installed at a suitable fluid-system connection, the valve provides a direct discharge route during abnormal conditions in HVAC systems. Its combined thermal and pressure response prevents excessive internal pressure buildup and maintains protected operating conditions.
