What are the characteristics of electric gate valve in the structure

Electric gate valve and flange gate valve is the same type of valve, by the electric actuator or pneumatic actuator and disconnecting valve two parts, the difference in its closing piece is a valve body, electric gate valve body around the body centerline for rotation to achieve open, close a valve. Electric gate valve in the pipeline is mainly used to do cut off, distribution and change the direction of media flow. Two-piece ball valve, three-piece ball valve, is a new type of valve that has been widely used in recent years.
Electric gate valve structural features:

  1, the selection of materials carefully, in line with domestic and foreign relevant standards, reasonable structure, beautiful shape.

  2, valve flap, valve seat sealing surface using iron-based alloy overlay welding or stearic cobalt hard alloy overlay welding, wear-resistant, high temperature, corrosion resistance, good anti-scuffing performance, long service life.

  3, electric gate valve stem by tempering and surface nitriding treatment, has good corrosion resistance and anti-scuffing.

  4, can use a variety of piping flange standards and flange sealing surface type, to meet the needs of various projects and user requirements.

  5, electric gate valve body material variety is complete, packing, gasket according to the actual working conditions or user requirements reasonable optional, can be applied to a variety of pressure, temperature and media working conditions.

  6、Inverted seal using threaded connection seal seat or body welded austenitic stainless steel, reliable sealing, replacement of filler can be carried out without stopping, convenient and fast, does not affect the operation of the system.

  7、Electric gate valve is equipped with multi-turn electric device, with a small shell, light weight, full function, and can be used with remote computer, and also according to user requirements optional electric device.

  The main advantages of electric gate valve are as follows:

  1、Small fluid resistance, its resistance coefficient is equal to the same length of pipe section.

  2, simple structure, small volume, light weight.

  3, tight and reliable, the current electric gate valve sealing surface materials are widely used plastic, good sealing, has been widely used in the vacuum system.

  4, easy to operate, open and close quickly, from fully open to fully closed as long as the rotation of 90 °, easy to control from a distance.

  5, easy maintenance, electric gate valve structure is simple, the seal is generally active, disassembly and replacement are relatively easy.

  6, in full open or fully closed, the ball and seat sealing surface and media isolation, the media through, will not cause erosion of the valve sealing surface.

  7, electric gate valve is widely applicable, the diameter from small to a few millimeters, large to several meters, from high vacuum to high pressure can be applied.
