Frequently Asked Questions
What is a swing check valve?
A swing check valve uses a hinged disc that opens with forward flow and closes automatically to prevent reverse flow. It is ideal for protecting pumps and equipment from backflow damage.
What is 5 kgf/cm² in PSI?
5 kgf/cm² is approximately equal to 71.1 PSI. This pressure rating suits many marine piping systems.
Is this bronze valve suitable for saltwater?
Yes, marine-grade bronze is highly corrosion-resistant and performs well in saltwater environments, making it a standard choice for seawater lines.
What sizes are available?
These valves are typically available in sizes from 1/2" to 2" with threaded connections. Please contact us for specific size availability.
