Dual Plate Check Valve (DPCV / NRV) by FlowBiz – Non-Return Flow Control

Reverse flow and water hammer can cause catastrophic damage to industrial pumps, compressors, and piping infrastructure. The FlowBiz Dual Plate Check Valve (DPCV / Non-Return Valve) is a compact, high-efficiency check valve designed to prevent backflow in liquid, gas, and steam utility systems.

Featuring twin spring-loaded plates hinged on a central pin, this valve opens easily under forward flow and closes rapidly prior to flow reversal. FlowBiz Exports Pvt. Ltd. manufactures these wafer-style DPCV units using high-grade stainless steel to deliver low pressure drop, silent operation, and reliable sealing across continuous process lines.

Key Applications Across Industries

The FlowBiz Dual Plate Check Valve is widely installed across high-velocity fluid networks to guard rotating equipment:

• Pump Discharge Protection: Prevents back-pressure and back-spin on centrifugal pumps and compressors.
• Water & Wastewater Treatment: Eliminates water hammer damage in municipal and industrial pumping stations.
• Chemical & Petrochemical Facilities: Safely manages aggressive process fluids, solvents, and hydrocarbons.
• HVAC & Cooling Towers: Maintained on chilled water lines and condenser circulating systems.

Why Choose FlowBiz Exports Pvt. Ltd.?

FlowBiz engineering prioritizes hydraulic performance and longevity across all non-return valve lines:

• Zero Water-Hammer: Torsion springs force the dual plates to shut before fluid momentum reverses, preventing pressure surges.
• Compact & Lightweight: Weighs up to 80% less than conventional full-body swing check valves, reducing pipe support costs.
• 100% Quality Inspected: Pressure tested for shell strength and seat leakage in full accordance with API 598 standards.
