Frequently Asked Questions
What is the pressure rating of this lift check valve?
The valve is rated for 16 kgf/cm², which is approximately 15.7 bar or 228 psi. This makes it suitable for medium-pressure marine systems, including steam, water, and oil lines.
What does an angle pattern lift check valve mean?
An angle pattern valve has inlet and outlet ports at 90 degrees to each other. This allows the valve to serve as both a check valve and a fitting to change flow direction, saving space and reducing the number of joints in piping systems.
Can this valve be used for seawater service?
Yes, the marine-grade bronze construction provides excellent resistance to seawater corrosion, making it suitable for shipboard seawater systems where backflow prevention is required.
How does a union bonnet benefit maintenance?
The union bonnet design allows the internal parts of the valve to be accessed without removing the entire valve from the pipeline. This simplifies inspection and cleaning, reducing downtime during maintenance.
