Plug valve 750-80

hydraulically-operatedlevel controlpilot

Product summary
Hydraulically operated control valve for automatic reservoir filling and level regulation. The valve closes at a preset high level and reopens fully in response to an approximate 1 m (3 ft) level drop detected by the 3-way altitude pilot mounted on the main valve.

Features & benefits

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

Double chamber design

• Moderated valve reaction for controlled movement
• Protected diaphragm for extended life
• Optional operation at very low inlet pressure
• Moderated closing curve to reduce hydraulic shock

Additional product highlights

• Flexible design — easy addition of optional features and pilots
• Obstacle-free flow passage
• V-Port throttling plug (optional) — very stable at low flow
• High-quality materials
• In-line serviceable actuator for easy maintenance
• Certified to functional and drinking water standards: EN-1074, NSF-ANSI 61-372, WRAS, AS 5081 and others

Typical applications

• Municipal systems — level control for water towers and elevated reservoirs
• Bi-level control for water refreshment and silent operation
• Potable water distribution and fire protection systems
• Irrigation infrastructure — Elevated Storage Reservoirs (ESR)

Notes
The altitude pilot (3-way) senses reservoir level variation and commands the main valve to maintain preset levels and to react to an approximate 1 m (3 ft) level drop.
