IMPA: 750671

Marine Forged Steel Angle Valve 40 kgf/cm² (IMPA 750671)

This marine forged steel angle valve is designed for demanding shipboard applications. Rated at 40 kgf/cm² (approximately 3.92 MPa / 568 psi), it provides reliable flow control in seawater, fresh water, fuel oil, lubricating oil, and compressed air systems. The 90° angle pattern minimizes pressure drop and simplifies piping layouts in engine rooms and machinery spaces.

Manufactured from high-quality forged steel, this angle valve offers exceptional mechanical strength, corrosion resistance, and durability in marine environments. It features a rising stem, leak-proof packing, and an ergonomic handwheel for precise throttling and positive shut-off. Threaded connections (BSP or NPT) allow easy installation in existing piping systems.

Compliant with IMPA 750671 classification, this valve is a versatile replacement for shipboard valves in commercial, offshore, and fishing vessels. Available in a range of sizes, it meets the demanding requirements of marine classification societies and ship chandler specifications.

Frequently Asked Questions

What does 40 kgf/cm² mean in psi?

40 kgf/cm² is approximately 568 psi (3.92 MPa). This is a common pressure class for marine valves used in high-pressure shipboard systems.

What thread types are available?

These angle valves are available with BSP (British Standard Pipe) or NPT (National Pipe Thread) connections to suit international shipboard piping standards.

Which media can this valve handle?

The valve is suitable for seawater, fresh water, fuel oil, lubricating oil, compressed air, and other non-corrosive or moderately aggressive fluids found onboard ships.

Can this valve be used for throttling?

Yes, the rising stem handwheel design allows precise flow control and positive shut-off, making it suitable for both on/off isolation and throttling duties.
