Key features

One-way flow: It's a non-return valve that automatically closes to prevent backflow in a pipeline.

Globe valve function: It can be used to control the flow rate of a fluid by adjusting the position of a disc, as well as to start or stop the flow.

Materials: The "cast iron" body provides durability and resistance to corrosion, which is essential for a marine environment.

Design: The "lift check" design uses a spring-loaded disc that is lifted by forward flow and falls back to its seat when the flow stops or reverses, with the disc also being moved by the valve's stem to control the flow.

Advantages

Multifunctional

It can achieve both check function and cut-off function, with high practicality.

Strong durability

Cast iron material has good durability and can operate stably in harsh environments.

Wide applicability

Suitable for the field of marine engineering, able to meet the needs of ships and marine equipment.

Lift design

With a lift structure, it can effectively prevent the reverse flow of the medium.

Excellent Material

Made of cast iron material, it has good corrosion resistance and strength, and is suitable for various media.

Compliance with standards

Complies with JIS F 7358 standard, ensuring its quality and performance meet regulatory requirements.

Components of Marine Lift Valves

Lift check valves the following key parts: the body, disc, and seat.

Body: The body houses the internal components and provides structural integrity.

Materials: Gunmetal, also known as red brass, is a common material for a lift check valve's body. It is an alloy of copper, tin, and zinc. Typically 88% copper, 8-10% tin, and 2-4% zinc. Gunmetal is corrosion and dezincification resistant.

Disc: The disc , which is often a plug or ball design, is the moving part that lifts to allow fluid flow and prevent backflow.

Seat: The seat is the sealing surface for the disc when closed.

Stud Bolt: Steel;

Hexagon Nut: Steel;

Set Screw: Steel;

Gasket: Non Asbestos;

How it works

Opening: When forward fluid pressure from the inlet is greater than the valve's cracking pressure, it lifts the piston-like disc off its seat, allowing the fluid to pass through.
Closing: When the forward flow slows or reverses, the force of gravity pulls the disc down, causing it to seat and shut off the reverse flow.
