3-Way Mixing Valve 714

The 3-Way Brass Mixing Valve 714 is used to mix supply water from a heat source with water

returning from a system. It is designed for use in either closed loop or open loop hydronic systems.

It connects to pipe using standard female NPT threads. The valve provides a maximum leak

through rate of 1% to allow for water expansion during temperature changes. The valve position

can be manually set using the handle. An Actuating Motor 741 can be used to automatically

operate the valve.

IMPORTANT: When mounting the valve, leave a minimum of 4” (10 cm) clearance between the bottom cover and surroundings.

This will ensure that all valve components can be easily serviced.

When the flap is in the fully closed position, 100% of the heating system return water is supplied to the system. When the

valve flap is in the fully open position, 100% of the boiler supply water enters the heating system. Mixing of the water takes

place when the valve flap is in an intermediate position.
