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.
• If installation is subjected to very low flow or potentially static conditions, AMES recommends a pressure
relief valve (1/2” minimum) be installed downstream of the Pressure Reducing Valve for additional system
protection.
