IMPA: 750481

Marine Cast Steel 40 kgf/cm² Angle Valves – IMPA 750481

The Marine Cast Steel 40 kgf/cm² Angle Valve (IMPA 750481) is a heavy-duty flow control solution engineered for the demanding conditions of shipboard piping systems. Its 90-degree angle pattern effectively replaces a standard valve and a separate pipe elbow, saving valuable space in engine rooms and hull compartments. With a working pressure rating of 40 kgf/cm² (approximately 570 psi), this valve delivers reliable performance in high-pressure hydraulic, fuel, and cooling water services.

Constructed from high-grade cast steel, the valve offers exceptional structural integrity, wear resistance, and resistance to seawater corrosion when properly coated. It is available with flanged, threaded, or welded end connections to suit various marine installation requirements. Whether used in ballast systems, fire mains, or lubricating oil lines, this angle valve ensures positive shut-off and low-pressure drop, meeting the expectations of international ship chandlers and marine engineers.

Frequently Asked Questions

What is a marine angle valve used for?

A marine angle valve is used to control the flow of fluids in shipboard piping systems at a 90-degree angle. It is commonly employed in engine room lines, ballast systems, and steam or water services to save space and reduce the need for additional pipe elbows.

Can this valve handle high-pressure steam?

Yes, the cast steel construction and 40 kgf/cm² rating make it suitable for saturated steam applications up to the stated pressure and temperature limits. Verify system temperature compatibility before installation.

What end connections are available?

The valve can be supplied with flanged, threaded, or butt-welded ends to match your ship’s piping specification. Flanged connections comply with international flange standards.

Is it suitable for seawater service?

While cast steel is not inherently corrosion-proof in seawater, a marine coating or lining can be applied for enhanced corrosion resistance. For raw seawater service, other materials may be recommended.
