Product Description

Product Description

Surge Anticipation Valve

Surge Anticipation Valve is indispensable for protecting pumps, pumping equipment and all applicable pipelines from dangerous pressure surges caused by rapid changes of flow velocity within a pipeline. When pumping systems are started and stopped gradually, harmful surges do not occur. However, should a power failure take place, the abrupt stopping of the pump can cause dangerous surges in the system which could result in severe equipment damage. Power failure to a pump will usually result in a down surge in pressure, followed by an up surge in pressure. The surge control valve opens on the initial low pressure wave, diverting the returning high pressure wave from the system. In effect, the valve has anticipated the returning high pressure wave and is open to dissipate the damage causing surge. The valve will then close slowly without generating any further pressure surges.
 

Key Features

1. Dual-Function Design
   • Combines the core functionality of the N20D dual-stage pressure reducing valve with advanced surge anticipation technology, ensuring seamless pressure transitions and water hammer prevention.
2. Smart Integration
   • Fully compatible with IoT-enabled systems, including:
     • PLC controls for automated adjustments.
     • Pressure sensors & flow meters for real-time monitoring.
     • Remote data transmission (SCADA/4G/5G) for centralized management.
3. Wide Application Range
   • Sizes: DN40-DN1200
   • Pressure Ratings: PN10/16/25/40, ANSI Class 150/300
   • Materials: QT500-7 (ductile iron), SUS304/316, SAF2205 (duplex), bronze.
   • Seals: NBR/EPDM/HNBR for chemical/thermal resistance.
4. Performance Highlights
   • Instant Response: Opens within <0.5 seconds during pressure surges.
   • Zero-Leak Closure: Drip-tight sealing even at zero flow.
   • Energy Efficiency: Reduces pump stress and pipeline wear, lowering operational costs.
