Hydraulically-operated valve 720

pressure-controlfor potable waterflange

Overview
Hydraulically operated pressure reducing control valve that lowers higher upstream pressure to a constant lower downstream pressure regardless of changing demand or upstream fluctuations.

Key features & benefits

• Excellent anti-cavitation performance
• Wide flow range
• High stability and control accuracy
• Drip-tight sealing

Double-chamber design

• Moderated valve response and closing curve
• Protected/isolated diaphragm option
• Optional operation at very low inlet pressures

Additional design & performance highlights

• Flexible modular design for easy addition of options
• Obstacle-free flow passage
• Optional V-Port throttling plug for stable low-flow control
• High-quality materials suitable for potable water
• In-line serviceable actuator for simplified maintenance
• Certified to drinking water and functional standards: EN-1074, NSF/ANSI 61-372, WRAS, AS 5081 and others

Typical applications

• Pressure management and NRW leakage control
• National and regional water supply pressure control
• Municipal systems — reducing pressure at potable water connections
• High- and mid-rise residential buildings — pressure zone inlet reduction
