100 Series Flow Control FLOW CONTROL & PRESSURE REDUCING VALVE Model IR‑172‑50‑3W‑XZt The BERMAD Flow Control and Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve that limits system demand to the designed maximum allowed value; reduces downstream pressure to constant preset maximum and shut in respond to hydraulic pressurized command. Line Pressure Driven Hydraulic Flow Control ■ Limits fill‑up rate and consumer excessive demand ■ Protects downstream systems ■ Adjustable paddle‑type hydro‑mechanic flow pilot with no added head loss ■ Easy flow and pressure setting with a wide setting range Engineered Composite Valve with Industrial Grade Design ■ Adaptable on‑site to a wide range of end connection ■ Highly durable, chemical and cavitation resistant hYflow 'Y' Valve Body with "Look Through" Design ■ Ultra‑high flow capacity at low pressure loss Unitized "Flexible Super Travel" (FST) Diaphragm and Guided Plug ■ Accurate and stable regulation with smooth closing ■ Requires low actuation pressure ■ Prevents diaphragm erosion and distortion ■ Simple in‑line inspection and service Typical Applications [1] BERMAD Model IR‑172‑50‑3W‑XZt limits over‑demand, controls laterals and distribution line fill‑up while reducing pressure. [2] Combination Air Valve Model IR‑C10 [3] Water Meter Model Turbo‑IR [4] RTU‑Remote Terminal Unit Operation: The Pressure Reducing Pilot (PRP) [1] is hydraulically connected to the control chamber [2] through the Flow Control Pilot (FCP) [3] . The PRP commands the valve to throttle closed should downstream pressure rise above setting and to fully open when downstream [P2] pressure drops below setting. The FCP commands the valve to throttle closed should demand rise above setting and to open fully when demand drops below setting. The Shuttle Valve [4] allows valve remote closing by introducing pressurized command to the control chamber, shutting the valve.
