Threaded Check Valve

Description

The Threaded Check Valve is a self-activating, automatic safety valve that allows fluid to flow in only one direction and prevents backflow when the flow stops. Whether you are using a Swing Check (for full-bore water flow) or a Spring-Loaded/Lift Check (for high-pressure or vertical installations), these valves are critical for protecting pumps, compressors, and sensitive instrumentation from the destructive force of reverse flow or "water hammer."

Technical Specifications

• Design Type: Swing Check (full-flow) or Spring-Loaded (low-noise/fast-closing)

• Operation: Automatic (Gravity or Spring-assisted)

• Connection: Female x Female Threaded (BSP/NPT)

• Body Material: Forged Brass, Bronze, or Stainless Steel (SS316)

• Pressure Rating: PN16 / PN25 / Class 150

• Installation: Can be installed in horizontal or vertical lines (depending on design)

Key Applications

• Pump Protection: Prevents water from rushing back into a pump after it turns off, which can cause severe mechanical damage.

• Water Distribution: Standard in domestic and commercial boosting systems to maintain line pressure.

• Heating/Cooling Loops: Prevents thermal siphoning in HVAC circuits.

• Industrial Manifolds: Vital in Ras Laffan and Mesaieed for protecting flow-sensitive downstream equipment.
