Product Name:welding forged steel gate valve
Product Classification:Gate valves
Product Introduction: There are three forged steel gate valve cover design, the first one is the bolt-type valve cover, through the concave and convex surfaces connected with the use of stainless steel and flexible graphite spiral wound gasket, ring connection can be used according to demand, the second is the welded bonnet , sealed by welding thread, according to demand rigid welded directly, the third is self-sealing valve cover, through the threaded connection with self-sealing valve cover
Description Parameters Size Chart Application
 

Fluid resistance, the sealing surface by erosion and water erosion medium.

 Opening and closing more effort.

 Medium flows unrestricted, non-spoiler, not reduce the pressure.

 Simple shape, structure, length of the short manufacturing process is good for a wide range.

 Z61Y forged steel gate valve defects are as follows:

 Between the sealing surface can lead to erosion and abrasion and maintenance more difficult.

 Size large, open needs some space, opening and closing a long time.

 More complex structure

Design and manufacturing: According to GB12224-89, GB12228-89, JB/T7746-95
 2, connector dimensions: (1) principal dimensions then JB1751-75 jack
 3, the valve inspection and test: GB/T13927-92
 4, the material
 (1) carbon steel according to the provisions of GB699
 (2) The provisions of stainless steel according to GB1220
 (3) heat-resistant steel according to the provisions of GB1221

 1, hand wheels, handles and drive mechanism for lifting are not allowed to use, and non-collision.

     2, Gate Valve should be installed vertically (ie, stem in a vertical position, the hand wheel at the top).

     3, the valve with a bypass valve opens the bypass valve in the open should be preceded by (in order to balance the import and export of pressure and reduce opening force).

     4, with the valve drive mechanism, according to the provisions of the product installation instructions.

     5, if the valve often used switches, lubrication at least once a month
