Brass Check Valves

Brass Check Valves for Reliable Backflow Prevention

Brass check valves are an essential part of many water, air and gas systems, providing dependable one-way flow control. Built from durable brass, these valves help prevent reverse flow that can damage equipment, contaminate clean water lines or reduce system efficiency. Their compact design, strength and corrosion resistance make them suitable for both residential and industrial use, where long service life and consistent performance are expected.

Common Types of Brass Check Valves

Brass Swing Check Valve

A swing-style valve uses a hinged disc that swings open when fluid flows in the correct direction and closes automatically if flow reverses. This design is simple, reliable and widely used in low to moderate pressure systems.

Inline Brass Check Valve

Inline valves feature a straight-through flow path, often spring-loaded, to allow forward flow while blocking reverse movement. Compact and easy to install, they are well-suited for confined spaces and applications requiring quick response to backflow.

Applications in Industrial and Commercial Systems

Brass check valves are commonly installed in:

• Plumbing systems to maintain clean water lines.

• HVAC and heating systems to protect pumps and equipment.

• Irrigation networks to prevent backflow into supply sources.

• Compressed air and light industrial gas systems.

Their ability to handle a range of fluids, including water, air and non-corrosive gases, makes them a practical solution in many industries.

Advantages of Brass Check Valves

• Durable construction: Brass provides excellent corrosion resistance and wear strength.

• Ease of installation: Compact designs fit easily between pipes or fittings.

• Reliable sealing: Helps minimize leakage and backflow risk.

• Cost-effective performance: An affordable option for both residential and industrial settings.
