Description
A marine gate valve is a linear motion valve designed to start or stop the flow of fluid in shipboard piping systems. It operates by raising or lowering a wedge-shaped gate between two seating surfaces, providing a tight seal when closed. Gate valves are typically used in applications where a full, unobstructed flow is required, but they are not ideal for throttling since partial opening can cause vibration and wear. In marine environments, they are built to withstand seawater corrosion, high pressure, and comply with Navy and MIL-SPEC standards for reliability and safety.
Sil-braze connections employ a brazing process using a silver-brasing alloy. Instead of threads, the pipe fits into a socket which has a channel cut into it. A brazing ring is inserted into the channel and the silver alloy is heated and melted into the gap. This creates a permanent bond between the fitting or valve and the pipe. Sil-Braze connections are exceptionally strong, leak-proof, and resistant to vibration.
Bronze is an alloy of copper and tin - often combined with additional elements to change the properties of the component material. It is durable, resistant to corrosion, and has a high melting point. Bronze is a highly versatile material utilized in many contexts including marine and seawater applications.
Tork Systems offers an extensive range of valves, pipe, fittings, and flanges that are critical to ship repair projects and other marine applications. Our markets include US Navy, Coast Guard, and Commercial marine vessels. Let our team of marine experts help you find the parts you need to Get Ship Done.
