Large-diameter stainless steel gate valve

First, the product uses 
Z41 gate valve products with small fluid resistance gate, the sealing surface erosion by erosion is small, does not change the media flow, no spoiler, pressure drop and other characteristics of the applicable pressure, temperature range, is a common cut off Valve, widely used in petroleum, chemical, thermal power plants and other oil products, water vapor pipeline connected or cut off the medium in the pipeline. (Do not use throttle).

 Second, the product features 
1 , the most commonly used wedge gate valve wedge seal formed two, wedge angle varies with the valve parameters, usually 50 ; wedge gate valve gate can be made as a whole, called the rigid gate ; Can also be made to produce micro deformation of the gate, to improve its technology to make up for the sealing surface angle in the process of deviation, this gate is called elastic gate; 2 , reliable sealing, excellent performance; usually Under the use of wedge-type elastic gate structure, the large diameter set rolling bearings, easy opening and closing; wedge gate valve shape is simple ,  short structure length, manufacturing process is good, wide range of applications; 3 , according to the user user selection bevel gear, electric , Pneumatic and other drives.
