Product Description
A200 Pressure Reducing And Stabilizing Valve
Product Overview
The A200 Pressure Reducing and Stabilizing Valve is a precision-engineered, direct-acting valve designed to automatically reduce and stabilize downstream pressure in water supply systems. It maintains consistent pressure levels regardless of fluctuating upstream pressure or variable flow rates, ensuring safe and efficient operation while protecting pipelines, fittings, and appliances from overpressure damage.
Key Features
- Automatic Pressure Control: Maintains pre-set downstream pressure with varying upstream pressure and flow demands
- Compact & Robust Design: Direct-acting mechanism eliminates external pilot line requirements, simplifying installation
- High Accuracy: Provides precise pressure regulation within defined ranges for system stability
- Wide Applications: Suitable for potable water, irrigation, industrial supply, HVAC, and fire protection systems
- Durable Construction: Available in brass, ductile iron, or stainless steel with corrosion-resistant components
- Easy Adjustment: External screw or knob allows downstream pressure adjustment without disassembly
- Low Maintenance: Simple design with fewer moving parts ensures long service life
Technical Specifications
- Size Range: DN15 to DN150 (½" to 6")
- Pressure Rating: PN16 / PN25 (standard)
- Inlet Pressure Range: Up to 25 bar (model-dependent)
- Outlet Pressure Range: Adjustable, typically 1.5 to 7 bar (standard)
- Connection Types: Flanged, threaded, or grooved ends
- Temperature Range: -10°C to 120°C (dependent on seals and materials)
Typical Applications
- Residential, commercial, and industrial water supply systems
- Municipal water distribution networks
- Irrigation and agricultural water management
- HVAC and hydronic systems
- Fire sprinkler and protection systems
- Process water lines in manufacturing plants
Installation & Maintenance
Install in accessible locations with sufficient clearance for adjustment and maintenance operations. Ensure flow direction matches the arrow indicated on the valve body. An upstream strainer is recommended to prevent debris from affecting valve performance. Periodic inspection and cleaning of the strainer and valve seat ensure optimal operation.
Benefits
- System Protection: Prevents pipe bursts, leaks, and appliance damage from excessive pressure
- Water & Energy Savings: Reduces waste and consumption by maintaining optimal pressure levels
- User-Friendly: Simple installation, adjustment, and maintenance procedures
- Versatile & Reliable: Consistent performance across diverse operating conditions
