IMPA: 751971

Bronze Screwed 150 PSI Gate Valves for Marine Use

Our bronze screwed gate valves are engineered for reliable performance in marine and industrial piping systems. Rated for a working pressure of 150 PSI (approximately 10 bar), these valves feature a robust bronze body that resists corrosion from saltwater, oil, and other fluids commonly handled aboard ships. The screwed (threaded) ends simplify installation, eliminating the need for welding or flanging and allowing for fast, secure mounting in tight spaces.

These gate valves are ideal for fuel lines, cooling systems, ballast handling, and freshwater distribution. When fully open, the full-bore design ensures minimal pressure drop and smooth flow. The rising stem provides visual confirmation of the valve position, while the ergonomic handwheel enables easy operation even with gloves or in confined quarters. Each valve is pressure-tested to verify integrity and complies with recognized marine standards.

Available in a range of sizes to match your shipboard requirements, these bronze gate valves are a dependable choice for new installations, maintenance upgrades, or emergency repairs. As part of our comprehensive ship chandler stock, this IMPA 751971 item supports global vessel procurement with quick dispatch.

Frequently Asked Questions

What is the maximum working pressure of these bronze gate valves?

These gate valves are rated for 150 PSI (approximately 10.3 bar) working pressure for non-shock applications at ambient temperatures. This makes them compatible with typical shipboard low- and medium-pressure systems.

What media can these valves handle?

The bronze construction allows for use with seawater, fresh water, oil, air, and fuel lines. However, for aggressive chemicals or steam, we recommend consulting with a marine engineer to confirm material compatibility.

What sizes are available?

We offer these valves in standard sizes from 1/4 inch to 4 inch with NPT or BSP threaded ends. Custom sizes and pressure classes can be supplied upon request for specific vessel requirements.

Are these valves tested for pressure integrity?

Yes, every valve is individually hydrostatically tested at the factory, and certificates of testing are available with each order. This ensures compliance with international quality standards.
