Frequently Asked Questions
What is the pressure rating of this valve?
This valve is rated for 5 kgf/cm² (0.49 MPa or 71 PSI), making it suitable for low-pressure marine piping systems such as ballast and cooling water lines.
Can this valve be used for seawater applications?
Yes, the cast iron body and corrosion-resistant trim are suited for seawater and brackish water. However, proper cathodic protection should be considered in the overall system design.
What is the difference between a screw down check valve and a standard check valve?
A screw down check valve allows manual closure of the disc using a stem, effectively acting as a shut-off valve while still preventing backflow. This dual function provides extra isolation capability without the need for a separate stop valve.
