Diaphragm valve IR-420-KXZ

hydraulically-operatedfor controldistribution

Overview
The BERMAD Pressure Reducing Valve IR-420-3W-KXZ is a hydraulically operated, diaphragm-actuated control valve that reduces higher upstream pressure to a lower constant downstream pressure regardless of fluctuating demand, and opens fully upon line pressure drop.

Hydraulic Pressure Control

• Line-pressure driven hydraulic control
• Protects downstream systems by maintaining set downstream pressure
• Fails open on line pressure drop to ensure supply continuity

Advanced Hydro-Efficient Globe Design

• Unobstructed flow path to minimise headloss
• Single moving part for simplified dynamics
• High flow capacity for irrigation and industrial distribution

Fully Supported & Balanced Diaphragm

• Low actuation pressure requirement
• Improved low-flow regulation performance
• Progressive valve closure for stable operation
• Prevents diaphragm distortion under varying loads

User-Friendly Design

• Simple pressure setting on site
• In-line inspection and serviceable components
• Modular design allows easy addition of control features

Typical Applications

• Pressure reducing stations
• Systems subject to varying supply pressure (irrigation distribution, industrial networks)

Additional Features

• I : Position Indicator Assembly
• M : Flow Stem
• 5 : Plastic Test Point
