BERMAD Irrigation 400 Series Pressure Reducing Drip-Tape Pressure Reducing Valve For Drip-Tape Applications IR-420-bKZ The BERMAD Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to very low and stable preset downstream pressure regardless of fluctuating demand, or varying upstream pressure. Line Pressure Driven Pressure Reducing Valve Protects downstream pressure Pressure Reducing Servo Pilot Controlled ❏ Dynamic integrated needle valve ❏ Settable to 0.5 bar; 7 psi ❏ Very low hysteresis Advanced Globe Hydro-Efficient Design ❏ Unobstructed flow path ❏ Single moving part ❏ High flow capacity Fully Supported & Balanced Diaphragm ❏ Requires low actuation pressure ❏ Excellent low flow regulation performance ❏ Progressively restrains valve closing ❏ Prevents diaphragm distortion User-Friendly Design ❏ Easy pressure setting ❏ Simple in-line inspection and service ❏ Drip-Tape Systems Low Set Pressure Applications Pressure Reducing Stations Low Supplied Pressure Irrigation Systems [1] BERMAD Model IR-420-bKZ establishes reduced pressure zone protecting laterals and distribution line.
