Some other common applications include unit ventilators, VAV box re-heat coils and bypass loops. This valve is suitable for use in hydronic system with constant or variable flow. These 3-way valves can be used for both mixing and diverting depending on the piping configuration.

For more information go to www.p65warnings.ca.gov Piping The valves 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 with actuator and for service. The G2 and G3 preferred mounting position of the valve is with the valve stem vertical above the valve body, for maximum life. However, the assemblies can be mounted with the valve stem vertical or horizontal in relation to the pipe. The actuators should never be mounted underneath the valve, as condensation can build up and result in a failure of the actuators.

Meets cULus requirements without the need of an electrical ground connection. A Actuators with appliance cables are numbered. Provide overload protection and disconnect as required. Actuators may also be powered by 24 VDC. Only connect common to negative (-) leg of control circuits. A 500 Ω resistor (ZG-R01) converts the 4 to 20 mA control signal to 2 to 10 VDC. Actuators may be connected in parallel if not mechanically linked. Power consumption and input impedance must be observed. Blk (1) Red (2) Wht (3) Org (5)
