Diaphragm valve IR-12T-55-3W-X

hydraulically-operatedelectrically-actuatedpilot

Overview
The BERMAD Top‑pilot pressure reducing control valve IR-12T-55-3W-X combines an integrated 3‑way pilot with an optional 3‑way solenoid for compact, plug‑and‑play pressure regulation in irrigation and water distribution systems. The high‑resolution adjustment dial enables fast, accurate calibration. The valve reduces higher upstream pressure to a calibrated constant downstream pressure regardless of flow variations and opens fully when line pressure falls below the setpoint. When a solenoid is fitted, the valve also opens and closes in response to an electrical control signal.

Features & Benefits

• Line‑pressure driven, hydraulically controlled On/Off
  • Protects downstream equipment and irrigation zones
  • Full opening on low line pressure for reliable supply
• Integrated 3‑way pilot — user‑friendly design
  • High‑resolution adjustment dial for calibration without external gauges
  • Compact "box‑size" layout simplifies valve station and panel installation
  • Solenoid control can be easily added or removed
  • Suitable across the full size range up to 3"
• Engineered composite valve with industrial design
  • Field adaptable to a wide range of end connections
  • Chemical and cavitation resistant for extended service life
• hYflow 'Y' valve body with "Look Through" design
  • Very high flow capacity with low pressure loss
• Unitized Flexible Super Travel (FST) diaphragm and guided plug
  • Accurate and stable regulation with smooth closing
  • Low actuation pressure requirement
  • Prevents diaphragm erosion and distortion
