IMPA: 751081

Marine Bronze Screw Down Check Angle Valve - IMPA 751081

This marine bronze screw down check angle valve, listed under IMPA 751081, is engineered for reliable backflow prevention in shipboard piping systems. Constructed from corrosion-resistant bronze, it withstands demanding marine conditions and delivers a working pressure rating of 5 kgf/cm² (approx. 0.49 MPa). The angle pattern integrates a 90° turn design, making it ideal for space-constrained installations where flow direction changes.

Featuring a screw-down or bolted bonnet design, this valve provides easy access for maintenance and inspection of the internal check mechanism. Threaded end connections simplify installation onto existing piping networks. Suitable for seawater, freshwater, fuel, and air services, this check angle valve is a dependable choice for engine rooms, ballast lines, and shipboard auxiliary systems.

As a stocked ship chandler product, this IMPA 751081 valve ensures quick availability for maritime repair and maintenance projects. Its robust bronze construction and compact angle body offer long service life and efficient flow control in both marine and land-based industrial applications.

Frequently Asked Questions

What is a screw down check angle valve?

A screw down check angle valve combines a check valve and angle (90°) body with a lift-type closure element that automatically prevents backflow. 'Screw down' refers to the screw-on bonnet or cover that allows access for inspection and maintenance.

What does the 5 kgf/cm² pressure rating mean?

It indicates the maximum working pressure the valve can safely handle — approximately 0.49 MPa or 71 psi. It is suitable for typical marine low-pressure systems.

Can this valve be used with seawater?

Yes, marine bronze construction offers excellent corrosion resistance, making it suitable for seawater, freshwater, and oil services in shipboard applications.

What end connections are available?

The valve features threaded ends, commonly available in BSP or NPT threads, allowing direct connection to standard pipe systems without welding or flanging.
