Installation Guidelines
• Prior to installation, flush line to remove debris.
• Install valve horizontally “in line” (cover facing UP), so flow arrow matches flow through the line. Avoid
installing valves 6” and larger vertically. Consult factory prior to ordering if installation is other than
described.
• Install inlet and outlet isolation valves. NOTE: When using butterfly valves, insure disc does not contact
control valve. Damage or improper valve seating may occur.
• Provide adequate clearance for valve servicing and maintenance.
• Install pressure gauges to monitor valve inlet and outlet pressure.
• Install Orifice Plate Assembly (provided) 3 to 5 pipe diameters downstream of the valve with the sensing
connections offset from top of pipeline to avoid air accumulation. The Orifice Plate Assembly should not
be installed next to a butterfly valve.
• Connect Orifice Plate Assembly to Rate-of-Flow Pilot using 3/8” diameter minimum copper tubing (field
installed) in accordance with factory piping schematic.
• Connect Solenoid and Limit Switch to appropriate pump control panel locations and power source in
compliance with local electrical codes.
