Globe valve WW-718-03

hydraulichydraulically-operatedseat

Product description
Line-pressure driven electronic control valve designed for precise modulating control. Responds to electronic controller signals to position the valve per programmed setpoints. Both opening and closing speeds are adjustable on site, enabling fine tuning for system dynamics and anti-cavitation performance.

Features & benefits

• Excellent anti-cavitation properties for extended component life
• Wide flow range for flexible process integration
• High stability and control accuracy for tight regulation
• Drip-tight sealing for leak-free operation

Double-chamber design

• Moderated valve reaction for smooth modulation
• Protected diaphragm to improve durability
• Option for operation at very low inlet pressures
• Moderated closing curve to reduce water hammer and transients

Additional features

• Flexible modular design — easy addition of options and accessories
• Obstacle-free flow path to minimize pressure loss
• Optional V-Port throttling plug for stable low-flow control
• High-quality materials selected for demanding environments
• In-line serviceable design for simplified maintenance
• Certified to functional and drinking water standards: EN-1074, NSF-ANSI 61-372, WRAS, AS 5081 and others

Typical applications

• Industrial and municipal pressure and flow regulation systems
• Mixing junctions and proportional blending control
• Water treatment and desalination process control
• Filtration systems — process flow regulation in filtration lines

How it is used

• Smart pressure & flow control in water distribution networks for energy-efficient operation
• Reservoir level and flow management — reliable control for storage facilities
