Water pressure regulator and reducer 720

for potable waterdiaphragmindustrial

Product overview
Hydraulically operated pressure reducing control valve model 720 (700 Sigma Series) that reduces a higher upstream pressure to a lower constant downstream pressure, regardless of fluctuating demand or varying upstream pressure. Designed for waterworks, buildings & construction and irrigation applications.

Features & Benefits

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

Double chamber design

• Moderated valve reaction
• Protected diaphragm
• Optional operation in very low pressure
• Moderated closing curve

Additional design attributes

• Flexible design - easy addition of features
• Obstacle-free flow path
• V-Port throttling plug (optional) - very stable at low flow
• High quality materials suitable for potable water
