Diaphragm valve 1020

hydraulically-operatedpressure-reducingfor water

Product Overview
Hydraulically operated pressure reducing control valve that lowers higher upstream pressure to a stable lower downstream pressure, independent of fluctuating demand or upstream pressure variations. Segment: Waterworks. Series: 1000 ES/EN. Model: 1020.

Features & Benefits

• Easy set-up
  • Super light weight for simplified handling
  • Line pressure driven – no external power needed
  • Pressure setting configurable on site or factory pre-set
  • Adaptable on-site to a wide range of end connections
• Simple and durable design
  • Excellent cavitation resistance
  • Corrosion-resistant construction (no rust)
  • Unitized actuator assembly – remove, replace, restore
  • In-line serviceable – no need to remove the valve from the pipeline
• Benefits of diaphragm-actuated control
  • Wide flow range
  • Stable low-flow performance
  • Drip-tight sealing
  • Obstacle-free flow passage
  • Easy addition of auxiliary features and accessories

Typical Applications

• Municipal water distribution – reducing pressure at potable water connections to buildings and structures
• Leakage reduction programmes – minimizing Non-Revenue Water
• Residential water supply – protecting pipes, fixtures and appliances from overpressure

How it is used

• Provides continuous controlled drinking water pressure in potable water systems by automatically reducing and stabilizing downstream pressure.
