RATE OF FLOW INSTALLATION
PLUMBING REQUIREMENTS
REMOTE MOUNT INSTALLATION
A straight length of pipe five pipe diameters long helps take out turbulence and will improve
valve performance. See Figure 1. Excessive turbulence caused by fittings, pipe size changes,
flow meters, and/or pumps immediately upstream of the valve can have a negative impact
on valve performance or even damage the flow-sensing paddle.
For applications where the pilot will not fit upstream of the valve, an after-market, in-valve
model is available (6” and 8” valves only). Contact factory for details.
The rate-of-flow pilot is intended to be installed in steel pipe. If attempting to install in PVC
pipe, be cautious of saddles or fittings that will prevent the paddle from moving freely or be-
ing entirely inserted into the flow path. This may cause the valve to regulate at a flow rate
that is dierent than the indicated value on the pilot calibration stem.
The rate-of-flow pilot is not intended to replace a flowmeter; having a flowmeter nearby will
assist in setting the pilot.
Install continuous acting air vents upstream of the rate-of-flow valve to prevent air entrap-
ment and water hammer.
