Diaphragm valve IR-120-3W-XZ

hydraulicregulatingpressure-reducing

Overview The BERMAD IR-120-Zb is a hydraulically operated, diaphragm-actuated pressure reducing valve designed to convert higher upstream pressure into a very low, stable preset downstream pressure. It maintains consistent downstream pressure regardless of demand fluctuations or upstream pressure variation and is optimized for drip-tape irrigation and in-field control heads.

Features and Benefits

• Line-pressure driven, hydraulically controlled
  • Protects downstream irrigation components and emitters
• Pressure-reducing servo pilot
  • Dynamic integrated needle valve for precise modulation
  • Settable as low as 0.5 bar (7 psi)
  • Very low hysteresis for stable regulation
• Engineered composite valve with industrial design
  • Durable, chemical- and cavitation-resistant construction
  • No internal bolts or nuts reduces risk of corrosion and failure
• hYflow 'Y' valve body with "Look Through" design
  • Ultra-high flow capacity with low pressure loss—suitable for long drip lines
• Unitized Flexible Super Travel (FST) diaphragm and guided plug
  • Accurate, stable regulation with smooth closing
  • Requires low opening and actuation pressure; prevents diaphragm erosion
• Simple in-line inspection and service

Typical Applications

• Drip-tape (drip-line) irrigation systems
• Low set-pressure irrigation zones
• Low supplied-pressure distribution networks
• Energy-saving irrigation schemes
