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 upstream 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 gauge to monitor discharge header pressure.
• Connect sensing line to main discharge header using 3/4” diameter minimum tubing / piping.
