Water pressure-limiting valve 1023

stainless steelbrassstainless steel

Overview
Hydraulically operated control valve with independent pressure-sustaining and pressure-reducing functions. Sustains a minimum preset upstream pressure regardless of fluctuating flow or downstream pressure, and prevents downstream pressure exceeding a preset maximum regardless of flow variations or excessive upstream pressure.

Features — Easy set-up

• Super lightweight
• Line-pressure driven — no external power required
• Easy pressure setting — on-site or pre-ordered
• Adaptable on-site to a wide range of end connections

Features — Simple and durable design

• Excellent cavitation resistance
• Highly durable, corrosion-resistant materials
• Unitized actuator — remove, replace, restore
• In-line serviceable — no need to remove from line

All the benefits of a diaphragm-actuated control valve

• Wide flow range
• Low-flow stability
• Drip-tight sealing
• Obstacle-free flow passage
• Easy addition of optional features

Typical Applications

• Municipal systems — Reducing pressure at potable water connections to buildings and structures
• Water delivery systems — Prioritizing upstream over downstream demand
• Water delivery systems — Maintaining upstream pressure during pressure drops
• Leakage reduction — Minimizing non-revenue water
• Residential water supply — Protecting pipes, fixtures and appliances
