Bell & Gossett V1000840 Ultra Setter Large Pressure Independent Control Valves - Manual (Page 11)

NOTICE:
Never use the valve as a form of piping support. Support the valves and piping according
to the local building code. Failure to follow these instructions may result in property
damage.
Install flanged connections
• Flanged Ultra Setter TM pressure independent control valves are not furnished with
companion flanges, gaskets, nuts, and bolts.
• Check and make sure the gaskets do not extend into the inside diameter of the pipe.
This will cause a blockage and affect the performance of the Ultra Setter TM .
• Check connections for leaks.
Install the actuator
Figure 1: Actuator Positioning
NOTICE:
To install an actuator on a valve already in line, close the shutoff valves (upstream first,
then downstream) in the piping or turn off the pump. This procedure allows the
differential pressure in the valve to drop.
Before installing the actuator, set the flow rate on the Ultra Setter TM pressure independent
balancing control valve. Follow the curve information in the product submittal to find the
required minimum differential pressure for the desired flow rate.
1. Grip the flats of the valve stem with a 7mm wrench and turn until the flow rate on the
adjacent GPM dial is in line with the indicator on the valve body.
