A brass check valve is a one-way valve designed to allow fluid (liquid or gas) to flow in only one direction, preventing backflow in pipelines. Made from durable brass alloy, it is resistant to corrosion and suitable for water, oil, gas, and other low-to-medium-pressure applications.
How Does It Work?
A brass check valve operates automatically without manual or external control. Its key components include:
- Body (Brass Housing) – Provides durability and corrosion resistance.
- Disc or Flap – A movable part that opens when fluid flows in the correct direction.
- Spring (in some models) – Helps the valve close quickly when flow stops or reverses.
Working Principle:
- Forward Flow (Open Position) – When fluid flows in the intended direction, the pressure pushes the disc open, allowing passage.
- No Flow / Backflow (Closed Position) – If flow stops or reverses, gravity, backpressure, or a spring forces the disc shut, blocking backflow.
Common Types of Brass Check Valves:
- Swing Check Valve – Uses a hinged flap that swings open/closed.
- Spring Check Valve – Uses a spring-loaded disc for faster closure.
- Lift Check Valve – The disc lifts vertically when flow is present.
Applications:
- Water supply systems
- Heating systems (boilers, pumps)
- Irrigation systems
- Compressed air & gas lines
- Industrial fluid control
Brass check valves are reliable, low-maintenance, and essential for preventing contamination, water hammer, and system damage caused by reverse flow.
