Frequently Asked Questions

What is a lift check globe valve?

A lift check globe valve is a type of check valve that uses a disc that lifts perpendicularly off the seat to allow forward flow. When flow reverses, the disc settles back onto the seat, preventing backflow. The globe-style body provides a tight seal and is commonly used in vertical or horizontal lines with clean fluids.

Can this valve be used in seawater systems?

Yes, the cast iron body is treated with a marine-grade corrosion-resistant coating, making it suitable for seawater applications. However, for prolonged exposure or higher chloride environments, consider adding cathodic protection or opting for a bronze or duplex stainless steel trim if required.

What pressure rating does this valve have?

The valve is rated at 5 kgf/cm², which is approximately 72 psi or PN6. This makes it ideal for low to medium pressure marine systems, including cooling water lines, bilge systems, and fuel oil transfer lines.

Are replacement parts available?

Yes, replacement seats, discs, and gaskets are available for this valve. Please provide the size and serial number when ordering to ensure correct fitment. We also offer complete valve assemblies under the same IMPA code 751311.
