BERMAD Irrigation Introduction 200 Series Valves The BERMAD 200 Series is a line of plastic hydraulic/electric control valves for residential, commercial and agricultural irrigation systems. This diaphragm actuated hydraulically operated plastic control valve combines simple and reliable construction with good hydraulic performance. These automatic water control valves are designed for vertical or horizontal installation and are available in Globe or Angle patterns in diameter sizes of ¾”-2”. The IR-200 valves are divided into two main types – Hydraulic Valve and Electric Valve. The...

BERMAD Irrigation Principle of Operation Closed Position Open Position Line pressure applied to the control chamber of the Discharging the pressure in the control chamber to valve creates a superior force that changes the valve atmosphere or some other lower pressure zone causes position to close, providing drip tight sealing. the line pressure acting on the seal disc to change the valve position to open. Locked Position When sensed pressure is equal to setting, the pilot shaft moves and blocks both the drain port and the pressure port. This locks the pressure in the control...

BERMAD Irrigation Principle of Operation 2-Way Solenoid Controlled, Normally Closed (N.C.) OFF Closed Position Open Position The internal restriction continuously allows line pressure into the control chamber. The solenoid controls outflow from the control chamber. When the solenoid is closed it causes pressure to accumulate in the control chamber, therefor forcing the valve to close. Opening the Solenoid releases more flow from the control chamber than the restriction can allow in. This causes the accumulated pressure in the control chamber to drop, enabling the line pressure acting on the...

PC-20-A-P, Plastic - 2-Way Pressure Reducing Pilot Valve This pilot integrates all principal functions of a 2-Way control circuit into a single assembly. It is a direct acting pilot valve, actuated by a pressure responsive diaphragm, which seeks to reach equilibrium between hydraulic and set spring forces. When used in a pressure reducing circuit, the pilot modulates to the closed position as downstream pressure rises above set point. An internal restriction acts as an upstream flow restrictor. Connections 1 or 2 - Downstream / Remote sensing 3 - Valve control chamber 4 - Upstream * Other...
