Frequently Asked Questions
What is the pressure rating of this gate valve?
The valve is rated for 10 kgf/cm², approximately equal to PN10 (1.0 MPa). This makes it suitable for low- and medium-pressure seawater and freshwater systems.
Is the valve suitable for seawater service?
Yes. The marine bronze construction provides excellent corrosion resistance, making it ideal for seawater, ballast water, and other saltwater applications found onboard ships.
How does the rising stem help during operation?
The rising stem moves up and down with the gate, giving a clear visual indication of whether the valve is open or closed. This feature helps engineers quickly verify valve status and reduces the risk of accidental closure or opening.
What sizes and end connections are available?
Standard sizes range from DN15 to DN300 (½" to 12") with flanged ends. Threaded and socket-weld ends can be made to order for specific requirements.
