VMT
2-way water valve
Application:
Features:
•Seated globe valve
•Brass body
•Low and high flow capacities
•Double union tail piece connections
The VMT is a 2-way valve used in controlling the flow of hot water within heating applications. The VMT valve can be installed in applications involving heating or chilled coils, hot water storage tanks, plate heat exchangers or floor heating systems. In the control of the VMT valve, a thermostatic operator type RAVK or
a 24VAC electric actuator type TWA-V or ABV can be mounted to the valve to regulate the temperature and flow through the valve. The VMT valves are available in ½”, ¾”, and 1” sizes and the double union connections are available in female sweat unions for ½” and ¾” and male NPT connections for 1”.
