Rain Bird PRS-Dial Valve Pressure Regulator

An adjustable pressure-regulating module for compatible Rain Bird commercial valves. It regulates downstream pressure while allowing the valve to be opened manually or closed fully.

• Rain Bird part number: B33135
• Adjustable outlet-pressure range: 1.04–6.9 bar
• Schrader valve connection for a pressure gauge
• Fits PGA, PEB, PESB, PESB-R, GB-R, EFB-CP-R, BPE and BPES valve families

Selection and installation

The inlet pressure must be at least 1.04 bar above the desired outlet setting. If inlet pressure exceeds 6.9 bar, Rain Bird specifies an upstream master valve or in-line regulator. Fit the module only to a compatible valve and adjust it with the system operating under normal flow.
