Boiler Feed Water Pump Protection Valve

Boiler Feed Water Pump Protection Solution -Thermal Power Plant| GEKO Valves       The Feed Water Pump Recirculation Valve is a critical protection valve designed to maintain the minimum required flow through boiler feed water pumps during low-load, startup, or shutdown conditions. By automatically diverting excess flow back to the feed water tank or deaerator, the valve prevents overheating, cavitation, vibration, and premature pump failure. GEKO Feed Water Pump Recirculation Valves are engineered for high-pressure and high-temperature boiler feed water systems, ensuring safe and reliable pump operation in power plants and industrial facilities.     Key Applications Thermal power plants Combined cycle power plants Boiler feed water systems High-pressure industrial boilers Petrochemical and refinery utility systems Desalination and water treatment plants   Main Functions Maintain minimum flow protection for feed water pumps Prevent pump overheating under low flow conditions Reduce cavitation, erosion, and vibration Extend pump and system service life Improve overall system reliability   Product Features & Advantages Automatic operation without external power or control system Accurate minimum flow control based on pump requirements Anti-cavitation and low-noise trim design Suitable for high pressure and high temperature service Long service life with minimal maintenance Available in forged steel, carbon steel, and alloy steel materials Designed in accordance with API, ASME, and power industry standards   Typical Technical Design Automatic recirculation or minimum flow control structure Multi-stage pressure reduction trim (optional) Integral orifice for stable flow control Horizontal or vertical installation options Flanged or welded end connections   Common Problems & GEKO Solutions   Problem 1: Feed Water Pump Overheating Low flow conditions cause rapid temperature rise inside the pump. GEKO Solution:The valve automatically opens to ensure continuous minimum flow, keeping pump temperature within safe limits.   Problem 2: Cavitation and Internal Erosion Insufficient flow leads to vapor formation and component damage. GEKO Solution:Optimized flow path and anti-cavitation trim reduce pressure drop and cavitation risk.   Problem 3: Excessive Vibration and Noise Unstable hydraulic conditions shorten pump and piping life. GEKO Solution:Stable flow regulation minimizes turbulence, vibration, and operational noise.   Problem 4: Manual Bypass Valve Failure Manual bypass valves depend on operator intervention and may be left closed or incorrectly adjusted. GEKO Solution:Fully automatic operation eliminates human error and ensures continuous protection.     Feed Water Pump Recirculation Valve,Boiler Feed Water Pump Protection Valve,Minimum Flow Control Valve,Feed Water Pump Bypass Valve,Automatic Recirculation Valve,Power Plant Feed Water Valve   Contact GEKO Valves Our engineering team is ready to support your boiler feed water pump protection requirements.
