Diaphragm valve WW-792-U

hydraulically-operatedpressure-reducingfor water

Description
Hydraulically operated, diaphragm-actuated burst control and pressure reducing valve with two independent functions: at flows below the setpoint it reduces higher upstream pressure to a preset lower downstream pressure regardless of demand or upstream variations; when flow exceeds the setpoint it shuts off drip-tight and locks until manually reset.

Key features & benefits

• Anti-cavitation performance for extended valve life
• Wide operating flow range
• Stable and accurate pressure control
• Drip-tight shut-off to prevent uncontrolled leakage

Double-chamber design

• Moderated valve reaction for controlled operation
• Protected diaphragm for improved durability
• Optional operation at very low inlet pressures
• Moderated closing curve to minimise hydraulic shock

Design & options

• Flexible modular design for easy addition of accessories
• Obstacle-free flow path to reduce wear and clogging
• Optional V-Port throttling plug for stable control at low flows
• Materials selected for potable water and industrial applications
• In-line serviceable design for simplified maintenance

Certifications

• Certified to EN-1074
• NSF/ANSI 61-372
• WRAS
• AS 5081
• Other functional and drinking water standards as applicable

Typical applications

• Old or sensitive pipeline networks — prevents flooding and water loss
• Reservoir level and flow control
• Municipal distribution networks, water resources, treatment and desalination plants
• Irrigation systems and industrial installations requiring rupture protection and pressure management
