Diaphragm valve IR-172-50-3W-Xt

hydraulically-operatedadjustmentpilot

Product overview
The BERMAD Flow Control and Pressure Reducing Valve IR-172-50-3W-XZt is a hydraulically operated, diaphragm-actuated control valve designed to limit system demand to a preset maximum, maintain a constant downstream pressure and respond to hydraulic shut-off commands. It is optimised for irrigation and field distribution systems.

Key features

• Line-pressure driven hydraulic flow control to limit fill rate and prevent excessive consumer demand
• Maintains preset reduced downstream pressure for stable operation of irrigation networks
• Adjustable paddle-type hydro-mechanic flow pilot with no added head loss
• Easy flow and pressure setting across a wide adjustment range

Engineered design

• Engineered composite construction for industrial-grade durability in agricultural environments
• On-site adaptability to a wide range of end connections
• Resistance to chemicals and cavitation for long service life

hYflow 'Y' valve body

• "Look Through" design for minimal obstruction
• Ultra-high flow capacity with low pressure loss — suited to large field mains and filter station bypasses

Unitized Flexible Super Travel (FST) diaphragm and guided plug

• Accurate, stable regulation with smooth closing action
• Requires low actuation pressure, reducing pilot energy needs
• Prevents diaphragm erosion and distortion for reliable field performance
• Simple in-line inspection and service to minimise downtime

Typical applications

• Line fill-up control for irrigation mains
• Pressure reducing systems for distribution networks
• Multiple independent consumer systems and laterals
• Systems with varying supply pressure
• Mechanized irrigation systems and center pivots
• Filter stations and washdown lines
