Water pressure relief valve 1030

for water systemshydraulically-operatedin-line

Overview
Hydraulically operated pressure relief and sustaining control valve (Model 1030, Series 1000 ES/EN) designed to perform two functions: sustain a preset minimum upstream pressure when installed in-line, or relieve excess line pressure when installed as a branched circulation (bypass) valve. Line-pressure driven, no external power required.

Features & Benefits

• Easy set-up
  • Super light-weight construction
  • Line-pressure driven — no external power
  • Simple pressure setting — configurable on-site or factory preset
  • Adaptable end connections for field installation
• Simple and durable design
  • Excellent cavitation resistance
  • Durable, corrosion-resistant materials
  • Unitized actuator — remove, replace, restore
  • In-line serviceable — no need to remove valve from line
• Diaphragm-actuated control advantages
  • Wide flow range
  • Stable performance at low flow
  • Drip-tight sealing
  • Obstacle-free flow passage
  • Easy addition of ancillary features

Typical Applications

• Pumping stations — pump circulation/recirculation valve
• Pumping stations — sustain pump discharge pressure to prevent overload and cavitation damage
• Water delivery systems — maintain upstream pressure during pressure drops
• Water distribution — prioritize upstream demand over downstream
• Municipal supply, desalination and treatment plants
