Working Principle of Water Flow Regulator Valves

Water Flow Regulator Valves maintain precise flow rates regardless of pressure fluctuations using pressure-compensating technology. Core functionality:

01.

Dynamic Pressure Balancing

Spring-loaded diaphragm automatically adjusts orifice size to maintain set flow (±2% accuracy) under 1–16 bar pressure changes.

02.

Turbo-Flow Design

Low-friction path achieves <0.15 bar pressure drop at maximum flow.

03.

Anti-Clog Protection

Vortex-scoured stainless steel filter (150 µm) traps debris without obstruction.

04.

Zero-Minimum Flow

Fully closes against ISO 5208 Class IV leakage when flow stops.

Key Advantages of Water Flow Regulator Valves

Energy Savings

Reduces pump workload by 20–35% through optimized flow control.

Scale Resistance

Diamond-Like Carbon (DLC) coated trim withstands 50,000 ppm hardness.

Installation Flexibility

Functions accurately in horizontal/vertical orientations.

Maintenance-Free

No external power or calibration required – 10+ year service life.

Hygienic Compliance

Electropolished SS316L meets 3-A/EC1935 standards for food/pharma.
