VMT
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 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
Features:
• Seated globe valve
• Brass body
• Low and high flow capacities
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”.
• Double union tail piece connections

Typical Installations:
Installation:
Hot water storage tank
Radiant system with electronic actuator
Floor heating system
Heat exchanger control
The valve body must be installed in the direction
of the flow as noted by the cast-in arrow located
on the body of the valve. Failure to install the
valve in the proper flow direction may result in
system noise during operation.
