Flanged Check Valve

Description

The Flanged Check Valve is an essential safety component for large-diameter industrial piping. By utilizing a secure flanged connection, it ensures a leak-proof integration into high-pressure systems. Its primary function is to allow fluid to flow in a single, desired direction while automatically closing to prevent backflow when the system pressure drops or the pump stops. This is the primary defense against "water hammer" and reverse-rotation damage in large-scale pumping infrastructure.

Technical Specifications

• Design Type: Swing Check (full-bore) or Dual-Plate (wafer/lug style)

• Connection: Flanged (ASME B16.5 / DIN / PN16 / PN40)

• Operation: Automatic (Gravity or Spring-assisted)

• Body Material: Cast Iron, Carbon Steel (WCB), or Stainless Steel (SS316)

• Pressure Rating: Class 150 / PN16 / PN40

• Installation: Horizontal or vertical (swing check must be horizontal or upward flow)

Key Applications

• Pump Discharge Protection: Essential for large-diameter pumping stations in municipal water and industrial treatment plants.

• Industrial Cooling Loops: Prevents backflow in massive heat exchanger and chiller water circuits.

• Critical Manifolds: Standard hardware for flow routing in Ras Laffan and Mesaieed industrial facilities.

• Municipal Water Networks: Provides long-term reliability for main line distribution systems.
