Gate valve is probably the first valve you think of in a ship piping system. It is widely used in the whole ship. Gate valves are valued for their simple form and effective function. Gate valves get their name from the wedge that moves up and down in the valve body to allow water or other media to pass through, much like a gate in a castle. Gate valves are well suited for on/off applications, but they should not be used to partially restrict flow in throttling situations, as the wedge-shaped gate is designed to handle this horizontal stress without seat support. Conventional gate valves consist of a valve body, bonnet or yoke, wedge plate, seat and stem, and handwheel. Gate valves can also be activated to allow remote control. Gate valves do come in a variety of forms, with connections ranging from socket welded and threaded to joint end welded and flanged. tork stocks a variety of gate valves, but our most common choice is the Monel alloy gate valve with a bronze body. Commercially, these valves are typically 150 lb. flanged. For the Navy, MIL-V-1189 is the military gate valve of choice. These valves are available in 100-pound, 250-pound (per NAVSEA DWG 803-2177917), or 400-pound and are equipped with flanges per MIL-F-20042.
