IR 420-55

Product catalog summary
Overview: The BERMAD Model IR-420-55 is a hydraulically operated, diaphragm-actuated pressure reducing valve with solenoid control. It is designed to reduce higher upstream pressure to a lower constant downstream pressure, regardless of fluctuating demand or varying upstream pressure.
Typical Applications: The valve is suitable for pressure reducing stations, flow and leakage reduction, cavitation damage protection, source and 'on duty' valves management, pressure zone isolation, downhill supply lines, and system maintenance savings.
Features and Benefits:
  • Line Pressure Driven PRV: Electrically controlled on/off, protecting downstream systems with a wide range of pressures and voltages. Available in normally open, normally closed, or last position configurations.
  • Advanced Globe Hydro-Efficient Design: Features an unobstructed flow path, single moving part, and high flow capacity.
  • Fully Supported & Balanced Diaphragm: Requires low opening and actuation pressure, offers excellent low flow regulation performance, progressively restrains valve closing, and prevents diaphragm distortion.
  • User-Friendly Design: Easy pressure setting and simple in-line inspection and service.
Technical Specifications:
  • Sizes: Available in sizes ranging from 3” to 16” (DN80 to DN400).
  • Pressure Rating: 16 bar; 232 psi.
  • Operating Pressure Range: 0.5-16 bar; 7-232 psi.
  • Materials: Body and cover made of polyester-coated cast or ductile iron, stainless steel spring, nylon fabric reinforced diaphragm, zinc-cobalt plated steel bolts, and brass control accessories.
  • Solenoid Voltage Range: 24 VAC, 24 VDC, with other voltages available.
Flow and Pressure Data: The document includes a flow chart illustrating the relationship between flow rates (in gpm and m3/h) and pressure drop (in psi and bar) for various valve sizes.
Ordering Information: The document provides a detailed guide on how to specify the requested valve, including options for materials, end connections, coating, voltage, and additional attributes.
