2-Way Motorized Isolation Valve
Figure 31: 2-Way Motorized Isolation Valve
Used in variable pumping type applications, the valve is
typically piped in the return water line. On a call for heat-
ing or cooling, the valve will open prior to the compressor
starting. The 24VAC valve actuator must be wired directly to
terminal block H8 on the MicroTech III controller. Seegure
23 on page 23 for wiring details.
The valve is rated for 300
psig (2070 kPa).
