Gate Valves are functional as the linear motion valves in which a flat end element gets slide into the flow stream. Highly advantageous in applications involving slurries and the ones that involve viscid liquids such as heavy oils, varnish, molasses, light grease, cream, honey, and other non-flammable sticky fluids. Made to handle the thick flow in a better way, Gate valves are designed for making a pressure drop across the valve. Also, these are capable to stop the flow of fluid entirely. These enable the optimum prevention of flow of liquids and thus are highly apt for petroleum industry. Made of ductile iron, these are offered in resilient soft seated, dual plates checked and floating structures.
