3-Way Mixing Valves 710 - 714

The 3-Way Brass Mixing Valves 710, 711, 712, 713, and 714 are used to mix supply water from

a heat source with water returning from a system. They are designed for use in either closed

loop or open loop hydronic systems. All valves have 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.
