A Brass Thread End NPT/BSPT Swing Check Valve is a type of check valve designed to allow fluid flow in one direction while preventing reverse flow (backflow) in a piping system. It is constructed from brass, a durable and corrosion-resistant material, and features threaded ends that comply with NPT (National Pipe Thread) or BSPT (British Standard Pipe Taper) standards. The valve utilizes a swing mechanism, where a hinged disc swings open to allow forward flow and closes to block reverse flow. This type of valve is commonly used in applications requiring reliable performance, compact design, and easy installation.

-
-
Swing Mechanism:
-
Utilizes a hinged disc that swings open with forward flow and closes with reverse flow.
-
The disc is designed to provide a tight seal when closed, preventing backflow.
-
-
Operation:
-
Works based on pressure differentials: the valve opens when upstream pressure exceeds downstream pressure and closes when the flow reverses.
-
No external actuation is required; the valve operates automatically.
-
-
Applications:
-
Commonly used in water supply systems, HVAC systems, compressed air systems, and irrigation systems.
-
Suitable for both horizontal and vertical (upward flow) installations.
-
-
