2-Way Water Valve

Application:

Ordering

Information:

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 tank, plate heat exchanger or ﬂoor

heating system. In the control of the VMT valve,

a thermostatic operator type RAVV or 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 1/2”, 3/4”, and 1” sizes

and the connections available are female solder

unions for 1/2” and 3/4” and male threaded

unions for 1”.
