Three-Way Valves
MAXIMUM WORKING PRESSURE: 700 PSIG
Features
The ‘TW’ series of three-way valves are 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 brass. It is a packed valve design with the imperative that the valve stem is 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″ Rotolock fitting. A PTFE gasket is supplied with the TW-14
- Brass body
- Temperature rating: -40°F to 300°F
- Suitable for all CFC, HCFC, and HFC refrigerants and their associated oils
