Marine Cast Steel Screw-Down Check Angle Valve – 10 kgf/cm2

This Marine Cast Steel Screw-Down Check Angle Valve (F-7472) is engineered for use in shipboard piping systems where reliability and space efficiency are critical. Constructed from high-grade cast steel, it offers outstanding strength and corrosion resistance in harsh marine environments. The valve integrates both a manual screw-down stop function and an automatic non-return check mechanism, providing versatile flow control and prevention of backflow.

Designed with a 90-degree angle pattern, this valve fits neatly into bulkheads and confined engine room spaces, reducing the need for extra bends and fittings. It is suitable for a wide range of media including seawater, fresh water, fuel oil, and saturated steam up to a pressure rating of 10 kgf/cm2 (1.0 MPa / 10 bar).

Each valve is manufactured to rigorous marine standards and is individually pressure-tested to ensure leak-proof performance. Whether you are maintaining a ship's fuel system, ballast line, or firefighting circuit, this screw-down check angle valve delivers dependable service with minimal maintenance.

Frequently Asked Questions

What is a screw-down check angle valve?

It is a combined stop and non-return valve with inlet and outlet at a 90-degree angle. The screw-down spindle allows manual closure, while the check mechanism automatically prevents reverse flow.

What is the maximum working pressure of this valve?

The valve is rated at 10 kgf/cm2, which is equivalent to 1.0 MPa or approximately 10 bar. This makes it suitable for most low-to-medium pressure marine applications.

What materials are used in this valve?

The valve body is made of cast steel (typically WCB), providing high strength and excellent corrosion resistance in marine environments. Alternative trim materials are available for highly corrosive or specific media.

Can this valve be used for steam lines?

Yes, the cast steel construction and pressure rating allow for use in saturated steam lines up to 10 kgf/cm2, subject to proper installation and operating conditions.
