Apollo Valves CON-18C5424125 Tp Relief Valve 125 Psi

Product Description

The APOLLO VALVES CON-18C5424125 is a temperature and pressure relief valve designed for use in water heating systems. It provides a critical safety function by automatically releasing excess pressure or temperature buildup before it reaches dangerous levels. This valve features a 1.5 inch female inlet connection, a 4 inch element length, a maximum working pressure of 125 psi, and a rated capacity of 5,125,000 BTU/h. It is installed by licensed plumbers and mechanical contractors on water heaters and storage tanks where code-mandated overpressure protection is required.

This relief valve is suited for residential and light commercial water heating applications. The 4 inch element length accommodates standard water heater installations, and the 125 psi pressure rating covers a broad range of system operating conditions. Plumbing inspectors and AHJs commonly require a properly rated T and P relief valve on any pressurized water heating vessel, making this a code-critical component in new installations and service replacements alike.
