IMPA: 751116

Marine Cast Iron Screw Down Check Angle Valve – IMPA 751116

This IMPA 751116 marine cast iron screw down check angle valve is specifically designed for shipboard piping systems where reliable backflow prevention and shut-off capability are essential. The robust cast iron body and angle pattern (90°) allow for compact installation in tight spaces, while the screw-down stem enables the valve to function as both a check valve and a manual stop valve, providing operators with added control and safety.

Rated for 5 kgf/cm² (71 PSI), this valve is suitable for seawater, fresh water, and ballast lines. The flanged connections comply with common marine piping standards (JIS10K, ANSI 125, DIN PN6) and the corrosion-resistant trim ensures long service life in harsh marine environments. As part of the IMPA 75 category, this valve is a standard ship supply item, ideal for new builds, retrofits, or onboard maintenance.

Frequently Asked Questions

What is the pressure rating of this valve?

This valve is rated for 5 kgf/cm² (0.49 MPa or 71 PSI), making it suitable for low-pressure marine piping systems such as ballast and cooling water lines.

Can this valve be used for seawater applications?

Yes, the cast iron body and corrosion-resistant trim are suited for seawater and brackish water. However, proper cathodic protection should be considered in the overall system design.

What is the difference between a screw down check valve and a standard check valve?

A screw down check valve allows manual closure of the disc using a stem, effectively acting as a shut-off valve while still preventing backflow. This dual function provides extra isolation capability without the need for a separate stop valve.

What sizes are available?

The standard range is DN15 to DN150 (1/2″ to 6″). Custom sizes may be available on request; contact us for specific requirements.
