DOWNLOAD PRODUCT BROCHURE

The BERMAD IR-120-54-3W-X is a hydraulically operated, diaphragm-actuated pressure reducing valve designed to precisely control downstream pressure in agricultural irrigation systems. This normally closed valve includes a hydraulic relay pilot that maintains a constant reduced downstream pressure, while fully opening when upstream pressure drops, ensuring responsive and protective control across varied conditions.

With its hYflow “Y” valve body, high-flow capacity, and low pressure loss, the IR-120-54-3W-X is ideal for large and medium-scale irrigation blocks using drip or sprinkler systems—especially where inlet pressure can fluctuate significantly.

APPLICATION

  • Drip and sprinkler irrigation control
  • Low-pressure supply zones
  • Energy-efficient irrigation networks
  • Agricultural irrigation headworks
  • Computerised irrigation systems
  • Distribution centres and filter stations

FEATURES

  • Hydraulically Controlled, Line-Pressure Driven
    • Maintains constant downstream pressure regardless of demand
    • Fully opens during line pressure drop
    • Ideal for pressure-sensitive irrigation schemes
  • Engineered Plastic, Industrial Grade Design
    • Highly resistant to chemicals and cavitation
    • Free of internal bolts and nuts for easier maintenance
  • hYflow ‘Y’ Valve Body with “Look Through” Design
    • Ultra-high flow capacity
    • Low head loss for optimal efficiency
  • FST (Flexible Super Travel) Diaphragm and Guided Plug
    • Stable regulation with smooth opening/closing
    • Requires low actuation pressure
    • Protects diaphragm from erosion and deformation
  • User-Friendly Maintenance
    • Simple in-line inspection
    • Compatible with a wide range of end connection sizes and types

INSTALLATION

  1. Ensure adequate space for servicing
  2. Flush pipeline thoroughly before installation
  3. Install upstream and downstream isolation valves
  4. Align valve with flow direction (horizontal upright recommended)
  5. After installation, check tubing, accessories, and fittings for damage

COMMISIONING & CALIBRATION

  1. Ensure inline filter is correctly oriented.
  2. Use the hydraulic cock valve to engage auto mode.
  3. Open upstream valve fully, then slowly open downstream valve to fill system.
  4. Bleed air from highest point in control loop and retighten fitting.
  5. Adjust pilot screw:
    1. Turn clockwise to increase set pressure
    2. Turn counter-clockwise to decrease
  6. Allow pressure to stabilise, then lock the pilot nut and open all valves fully.
