Marine Bronze Angle Lift Check Valve – Union Bonnet Type (16 kgf/cm²)

The Marine Bronze Angle Lift Check Valve is a high-quality check valve specifically engineered for marine and industrial applications. Constructed from marine-grade bronze, this valve offers excellent resistance to seawater corrosion, ensuring long service life even in harsh shipboard environments. The valve features a compact angle pattern (90°), which allows for efficient flow redirection while minimizing pressure loss, making it an ideal choice for confined spaces common in engine rooms and piping systems.

This lift check valve is designed with a union bonnet type cover, simplifying maintenance and inspection while keeping the valve tightly sealed under pressure. The reliable lift check mechanism provides positive backflow prevention for water, steam, oil, and other compatible media. With a pressure rating of 16 kgf/cm² (approx. 15.7 bar), it is suitable for medium-pressure ship service lines. Threaded end connections ensure easy installation and compatibility with existing piping systems.

Available in a range of sizes, the valve is a dependable component for ship chandlers, marine engineers, and vessel operators looking to maintain safe and efficient fluid control systems. Whether for engine cooling lines, fuel systems, or steam lines, this bronze angle lift check valve delivers reliable performance and low maintenance.

Frequently Asked Questions

What is the pressure rating of this lift check valve?

The valve is rated for 16 kgf/cm², which is approximately 15.7 bar or 228 psi. This makes it suitable for medium-pressure marine systems, including steam, water, and oil lines.

What does an angle pattern lift check valve mean?

An angle pattern valve has inlet and outlet ports at 90 degrees to each other. This allows the valve to serve as both a check valve and a fitting to change flow direction, saving space and reducing the number of joints in piping systems.

Can this valve be used for seawater service?

Yes, the marine-grade bronze construction provides excellent resistance to seawater corrosion, making it suitable for shipboard seawater systems where backflow prevention is required.

How does a union bonnet benefit maintenance?

The union bonnet design allows the internal parts of the valve to be accessed without removing the entire valve from the pipeline. This simplifies inspection and cleaning, reducing downtime during maintenance.
