Hydraulically-operated valve 723

pressure-controlpressure-reducingpressure sustaining

Overview
Hydraulically operated control valve combining independent pressure sustaining and pressure reducing functions. It maintains a preset minimum upstream pressure regardless of fluctuating flow or varying downstream pressure, and prevents downstream pressure from exceeding a preset maximum irrespective of flow changes or excessive upstream pressure.

Key Features

• Excellent anti-cavitation properties
• Wide flow range
• High stability and accuracy
• Drip-tight sealing
• Double-chamber design for moderated valve reaction
• Protected diaphragm
• Optional operation at very low pressure
• Moderated closing curve
• Flexible design — easy addition of features
• Obstacle-free flow passage
• V-Port throttling plug (optional) — very stable at low flow
• High-quality materials
• In-line serviceable — easy maintenance
• Certified to functional and drinking water standards (EN-1074, NSF-ANSI 61-372, WRAS, AS 5081 and others)

Typical Applications

• Municipal systems — reducing pressure at potable water connections to buildings and structures
• Water distribution systems — prioritizing upstream over downstream demand
• Water delivery systems — maintaining upstream pressure during pressure drops

Additional Information

• Double-chamber actuator option available
• Obstacle-free flow path and unobstructed seat area to reduce head loss
• Anti-cavitation options available for severe service
• Extensive documentation and spare-parts resources available (product pages, IOM, ordering guide, engineering documents)
