GD type-high vacuum baffle valve


GD type high vacuum baffle valve is used to connect or cut off the air flow in the vacuum pipeline. The applicable medium is pure air and non-corrosive gas. According to the shaft seal structure, the high vacuum flapper valve can be divided into two types: GD-J rubber shaft seal and GD-J(b) bellows shaft seal. According to the conduction form, it can be divided into GD-J as the angle pass type, and GD-S as the three pass type with pre-exhaust.



 

Material of main parts


Valve body, valve cover, valve stem: aluminum alloy, carbon steel or stainless steel


Seals: Butadiene rubber, Viton, bellows (shaft seal)



Zhejiang Gaochuan Machinery Technology Co., Ltd. has been serving the production and research and development of industrial valves, focusing on the localization of industrial valves. The company is equipped with a technology research and development center, with advanced CAD, Solidworks, and Pro-E research and development software. It is committed to improving the global valve supporting capabilities and innovation capabilities, and providing a complete set of solutions for the world's valves.


The materials of commonly used high and low vacuum valves and sealing gaskets are all rubber, which cannot withstand the high and low vacuum of commonly used high and low vacuum valves. The sealing gasket materials are all rubber, which cannot withstand high temperature baking, so it cannot be used for ultra High vacuum equipment. Ultra-vacuum valves that can be used in ultra-vacuum equipment must meet: (1) able to withstand high temperature (400~450℃) multiple baking; (2) small exhaust volume and good air tightness; (3) reusable; ( 4) Have good conductance.
