Couldn't load pickup availability
The Bronze Swing Check Valve – PN25 – NPT is designed to ensure one-way flow in piping systems, effectively preventing backflow and protecting downstream equipment. With a PN25 pressure rating and NPT threaded ends, it’s compatible with standard American and international threaded pipe systems.
The swing-style disc opens automatically with forward flow and closes when flow reverses, delivering smooth, quiet operation and low pressure drop. Constructed from corrosion-resistant bronze, this valve is ideal for use in water, steam, air, and non-aggressive fluid systems across marine, industrial, and HVAC environments.
Key Features:
- PN25 pressure rating (25 bar max)
- NPT threaded ends for secure, standardised installation
- Swing disc mechanism for efficient backflow prevention
- Bronze body for durability and corrosion resistance
- Suitable for horizontal installation in water, air, steam, and gas lines
- Ideal for marine, industrial, and mechanical plant applications

FAQs
What are bronze valves used for?
Bronze valves are commonly used for isolating, regulating, and directing the flow of water, steam, air, and non-aggressive fluids in industrial, marine, and commercial systems. Their corrosion resistance makes them ideal for saltwater and outdoor applications.
Are bronze valves suitable for potable water?
Yes, bronze valves are often used in potable water systems, especially when made from lead-free or WRAS-approved bronze alloys. Always verify material compliance with local drinking water standards.
What is the difference between bronze and brass valves?
Bronze is an alloy of copper and tin, offering better corrosion and wear resistance than brass, which is typically made of copper and zinc. Bronze valves are generally more durable and preferred for marine and industrial applications.
Can bronze valves handle high temperatures and pressures?
Yes, most bronze valves are rated for moderate to high temperatures and pressures. Many models can handle up to PN25 or 600 psi, and temperatures ranging from -10°C to 150°C, depending on design and sealing materials.
Do bronze valves require regular maintenance?
Bronze valves are low-maintenance, but like any mechanical component, periodic inspection and cleaning (especially strainers and check valves) are recommended to ensure long-term performance and safety.
