Setting the Pressure Reducing Control
Note: Starting up the system will require bleeding air and draining water from the valve. Take proper precautions to protect your
space from water damage.
Note: Start with the upstream and downstream isolation
valves in your system closed, Labeled 1 and 2 in Figure 1
respectively.
STEP 1
Pre-set pilots as noted:
Pressure Reducing – Adjust OUT, counterclockwise, back-
ing pressure off the spring, preventing possible over-pressur-
ing of the system (See Images 1 and 2).
Opening and Closing Speed – Turn the adjustment screws
on the Closing Speed and Opening Speed Controls, if the
main valve is so equipped, OUT, counterclockwise, 11/2 to 21/2
turns from full closed position (See Images 3 and 4).
