Application
KH3-series single seat, three-way mixing valves control water for 2-position or modulating control applications. 125 psig pressure rating per ANSI Standards for flanged cast iron bodies.

Actuators
A number of combinations are possible. Both spring return and non-spring return actuators are available with appropriate linkages.

Piping
The valve should be mounted in a weather-protected area in a location that is within the ambient limits of the actuator. Allow sufficient room for valve linkage, actuator, and other accessories and for service. The preferred mounting position for the valve stem vertical above the valve body. “A” port is inlet, “B” port is bypass, “AB” port is outlet. Do not reverse flow direction.

WARNING
These valves are not for combustible gas applications as leaks and explosions could result.
