For nearly a hundred years, the most common valves on ships and barges were gate, globe and check valves. Extra space is always at a premium on a ship. In the case of gate valves, the outside screw and yoke, rising stem design, often took up too much valuablespace onboard. This resulted in the adoption of the non-rising stem (NRS) design, which became commonplace because of the additional headroom it afforded above the handwheel. The venerable gate valve is still used primarily in marine applications.
Many tankers and tank barges are required to haul different fluids in multiple onboard tanks. The loading and diverting valves feeding these tanks are usually required to have block and bleed capability to keep from cross contaminating their liquid cargoes.
Automation has become very common on modern ships, and this translates to the piping systems. Automated valve packages are seen more and more in the engineering rooms of modern vessels. These systems often interface with sophisticated computer systems that are used to control all of the common shipboard engineering functions.Bundor has butterfly valves,gate valves,ball valves and check valves,which can adjusted to various environments,so choose Bundor,Bundor is your best valve partner.
