The Bronze Globe Valve – PN25 – SDNR is a dual-function valve that combines positive shut-off with non-return capabilities. Designed for systems requiring both flow regulation and backflow prevention, this valve is ideal for steam, water, air, and non-aggressive fluid services operating at pressures up to 25 bar.
Built from high-quality bronze, it features excellent corrosion resistance and durability. The SDNR design allows the valve to close manually while also preventing reverse flow when open — a smart solution for marine, boiler, and industrial applications.
Key Features:
- PN25 pressure rating (25 bar max)
- SDNR (Screw-Down Non-Return) functionality
- Combines isolation and backflow prevention
- Bronze construction for long-term corrosion resistance
- Suitable for steam, water, air, and general-purpose fluids
- Ideal for marine, HVAC, and pressure systems

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.
