PESB and BPES Series ValvesBuilt-in rugged performance for the toughest field conditionsThe heavy duty PESB and BPES valvesare designed to handle dirty waterand pressure surges often found inagricultural irrigation systems. Bothfeature the patented nylon scrubberdevice, which scrapes a stainless steelscreen every time the valve opens andcloses This prevents debris build-upand clogging, with no externalpiloting. The PESB 1", 1 1/2", and 2"series globe valves are constructed ofindustrial-strength glass-filled nylonwith stainless steel studs for long termservice and easy maintenance.The BPES 3" series globe / anglevalves feature brass body and glassfillednylon bonnet construction.Both are built to withstand 200 psi(13,8 bars) operating pressure. Anexternal bleed manual operation isstandard for evacuating debriswithout passing through the solenoidports. And their low flow operatingcapabilities ensure reliable operationfor both sprinkler and micro irrigationsystems.PESB and BPES Features• Durable glass-filled nylonconstruction (BPES has heavy dutybrass body) rated to 200 psi(13,8 bars)• Patented scrubber mechanism toresist clogging of internal ports• Manual internal and external bleedPressure regulation operationwithout electrical signal usinginternal bleed (BPES model -turn adapter)• Globe configuration (BPES only:Globe and angle configuration)• Convert to pressure regulatingoperation by adding PRS-Dmodule (Shown with BPES)Operating Range• Pressure: 20 to 200 psi(1,38 to 13,8 Bars)• Flow: 0.25 to 300 gpm(0,06 to 45,40 m 3 /h;0,02 to 12,60 l/s)Models• 100PESB 1" NPT (25mm)• 150PESB 1 1/2" NPT (40mm)• 200PESB 2" NPT (50mm)• 300BPES 3" NPT (75mm)Notes:1.Valve and PRS-D module must be ordered separately2.
