Bermad IR-120-55-2W Plastic Hydraulically Operated Pressure Reducing Valve with 2-Way S.390 Coil

The Bermad 100 series pressure reduction valve is designed for irrigation headworks. It is switched on via an electric solenoid, and when open it regulates the downstream pressure to a constant value regardless of flow or inlet pressure. The solenoid can be AC, DC, or DC latch, which is typically mounted on the valve body.

APPLICATION

• Designed for vertical or horizontal installation
• Designed for service on a wide range of pressure and flow conditions
• Control drip irrigation systems and Sprinkler Systems
• Computerized Irrigation Systems ֺ
• Distribution Centers ֺ
• Low Supplied Pressure Irrigation Systems ֺ
• Energy Saving Irrigation Systems

FEATURES

• No chattering or slamming closed
• Accurate and stable regulation with smooth motion
• Low operating pressure requirement
• No diaphragm erosion and distortion
• Diaphragm and spring fully meet the valve’s operating pressure range requirements
• No UV and frozen effect
• Chemical resistant Designed for service under a wide range of pressure and flow conditions, from dripping to maximum flow, the IR-100 hYflow excels at being a userfriendly control valve:
• Simple design with few parts guarantees easy in-line inspection and service.
• Adaptable on-site to a wide range of end connection types and sizes.
• Articulated flange connections isolate the valve from pipeline bending and pressure stresses.

INSTALLATION

1. Ensure enough space around the valve assembly for future maintenance and adjustments. 
2. Prior to valve installation, flush the pipeline to insure flow of clean fluid through the valve.
3. For future maintenance, install Isolation gate valves upstream and downstream from Bermad control valve.
4. Install the valve in the pipeline with the valve flow direction arrow in the actual flow direction.
5. For best performance, it is recommended to install the valve horizontally and upright.
6. After installation carefully inspect/correct any damaged accessories, piping, tubing, or fittings.
7. Cross-Check solenoid specifications with design requirements and solenoid/coil label.
8. Ensure approved cable protection. Confirm that the wires data meet solenoid specifications. Note: Energizing the solenoid coil when it is not fixed in its place, is dangerous and might burn the coil.

COMMISIONING & CALIBRATION

1. Confirm that the In-line filter arrow [4A] direction is in the valve flow direction. 2
2. Allow the valve to open by using the solenoid manual override or by: Operating the solenoid.
3. Open fully the upstream isolating valve and slowly open the downstream isolating valve, to fill-up, carefully, the consumers' line downstream from the Valve.
4. Vent air from the valve's control loop by loosening cover tube fitting at the highest point, allowing all air to bleed. Then Retighten the tube fitting.
5. The IR-120-55-X is factory set according to the design. The set pressure is marked on the pilot label, If the set pressure is either different from the design or the requirements have been changed, change settings according to the following:
6. 5.1. Unlock the pilot locking nut and slowly turn the pilot adjusting screw Clock-Wise to increase set pressure and Counter Clock-Wise to decrease it. Allow the 120-55-X- to react and the downstream pressure to stabilize.
7. 5.2. After the pressure is stabilized lock the pilot nut.
8. 6. Check valve solenoid control feature by De-Energizing & Energizing the solenoid to close & open the valve.
