Professional inspection team and advanced quality inspection instruments. -Delivery on time: Own casting factory, large inventory, multiple production lines -After-sales service: Arrange technical personnel on-site service, technical support, free replacement -Free sample, 7 days 24 hours serviceThe opening and closing part of the cast steel gate valve is the gate plate, the direction of motion of the gate plate is perpendicular to the direction of the fluid, the gate valve can only be fully opened and fully closed, and can not be adjusted and throttled. The two sealing faces of the most commonly used mode gate valves form wedges, and the wedge Angle varies with the valve parameters, usually 50, and 2°52' when the medium temperature is not high. The gate plate of the wedge valve can be made into a whole body, which is called the rigid gate plate; It can also be made to produce a micro deformation of the ram, in order to improve its processability, make up for the sealing surface Angle in the processing of the deviation, this ram is called elastic ram.

-Simple structure: The structure of gate valve is relatively simple, mainly composed of valve body, gate plate, seal and operating mechanism, easy to manufacture and maintenance, easy to use. -Good truncation: the gate valve is designed as a rectangle or wedge, which can completely open or completely close the fluid channel, with good truncation performance, and can achieve a high sealing effect. -Low fluid resistance: When the ram is fully opened, it is basically flush with the inner wall of the fluid channel, so the resistance of the fluid is small, which can ensure the smooth flow of the fluid. -Good sealing: The gate valve is sealed by the contact seal between metal and metal or the gasket seal, which can achieve a good sealing effect, and the leakage of the medium can be effectively prevented after the valve is closed. -Wear-resistant and corrosion-resistant: the gate valve disc and seat are usually made of wear-resistant and corrosion-resistant materials, which can meet the needs of various working conditions. -Wide range of use: gate valve is suitable for a variety of media, including liquid, gas and powder, etc., widely used in petroleum, chemical, electric power, metallurgy, construction and other industries. -High pressure capacity: the gate valve adopts a fixed gate plate, and its valve body can withstand higher pressure when the gate is closed, and has a good pressure capacity. It should be noted that the gate valve due to the large friction between the valve flap and the sealing surface during the switching process, so the switching torque is large, and it is generally operated manually or electrically. In the need for frequent switching and high switching time requirements, it is recommended to use other types of valves, such as butterfly or ball valves.-Full or Reduced Bore -RF, RTJ, or BW -Outside Screw & Yoke (OS&Y), rising stem -Bolted Bonnet or Pressure Seal Bonnet -Flexible or Solid Wedge -Renewable seat rings
