Three-Way Valves

The TW series of three-way valves is designed to fulfill the requirements of ASHRAE standard 15, which states that all vessels over 10 cubic feet of internal volume must have a dual relief valve assembly. The three-way valve is made of nickel plated steel. It is a packed valve design and the
packing can be replaced if necessary. It is imperative that the valve stem be either front-seated or back-seated to insure only one relief valve assembly is active. The TW-14 is made to connect to a standard 1-1/4"-12 Rotolock fitting. A Teflon gasket is supplied with the TW-14.
