OverviewHydraulically 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
