Frequently Asked Questions
What is a screw down check angle valve used for?
It is used to prevent backflow in marine piping systems, allowing flow in one direction only. The angle pattern changes the direction of flow by 90 degrees.
What does 5 kgf/cm² mean in terms of pressure?
5 kgf/cm² is approximately 0.49 bar or 72 psi, representing the valve's maximum working pressure.
Can this valve be used with seawater?
Yes, the marine bronze construction makes it highly resistant to seawater corrosion, making it suitable for shipboard seawater and freshwater systems.
Why is a union bonnet design beneficial?
The union bonnet permits quick access to the internal components without detaching the entire valve from the pipeline, simplifying maintenance and reducing downtime.
