The valve chest is a product of Marine Dubai and Sharjah, which is in the form of a rectangular box on top of the engine cylinder. In fact, the Cutoff Valve regulates live steam to the main valve in marine land ports, which in turn transmits it to the alternating end of the engine cylinder and pushes the piston back and forth.
Replacement valves are replacement valves that change from one pipeline to another. They are sometimes called "selector" valves. Replacement valves are well suited for applications in which forced pressure devices (ruptured discs and relief valves) are installed as dual devices.
