Apollo Valves CON-19KFEA125 Steam Safety Relief Valve

Product Description

The APOLLO VALVES CON-19KFEA125 is an ASME Section I and Section VIII certified bronze safety relief valve designed for overpressure protection on steam power boilers, pressure vessels, pressure piping systems, and related equipment. The valve features a brass trim configuration with a Teflon (PFA) seat and connects via 1 inch male NPT inlet and 1-1/4 inch female NPT outlet. It is rated for set pressures from 5 to 300 psig and handles operating temperatures from -60 degrees F minimum to 406 degrees F maximum. Licensed plumbers, pipefitters, and boiler mechanics are the primary installers of this valve in commercial and industrial steam system applications.

This safety relief valve is suited for steam, air, and non-hazardous gas service across a range of system configurations including steam power boilers and pressure piping assemblies. The 19 Series is available in inlet connections from 1/2 inch through 2-1/2 inch, making this 1 inch x 1-1/4 inch configuration a mid-range option within the series. The valve is manufactured in the USA and carries CRN certification, making it appropriate for installations that require documented capacity certifications and provincial or state regulatory compliance.

Installation Notes

Installation of ASME-certified safety relief valves on boilers and pressure vessels must be performed by a licensed pipefitter, plumber, or boiler mechanic in accordance with applicable ASME Boiler and Pressure Vessel Code requirements and local jurisdictional rules. Always depressurize and isolate the system completely before removing or installing any safety valve. The valve must be installed in the upright vertical position with the outlet unobstructed and piped to a safe discharge location per applicable codes. Never plug, cap, or adjust the set pressure of a safety relief valve in the field.
