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.
