The SV-450 valve is specifically designed for use with a boiler water level gage glass.

This valve is supplied as a valve set including one top valve, and one bottom valve. Each valve has 3 connection ports available in a wide range of sizes and types, (vessel x gage x vent/drain).

The angled flow path facilitates compact installation of the gage glass, bringing the assembly connection point to the side. The offset body pattern allows a direct path around the stem to clean through the vent/drain ports.

The standard vent/drain ports are 1/2" Female NPT, 3/4" Female NPT and SW are also available. 

As a Questtec standard supplied with plain closing hand wheel with 2-1/2 turns. Ball checks are omitted in standard form, and available as an option. Ball checks are neither required nor prohibited by ASME Section I.
