Product Description

Guide, Upper Valve is a mechanical part widely used in industrial production, which is mainly used to provide axial positioning and support. The following is a detailed introduction to the Guide, Upper Valve:

Guide, Upper Valve is usually made of polytetrafluoroethylene resin pressed into blank parts, after sintering, cooling, and then according to the geometric size and tolerance range required by customer drawings, the mechanical cutting method is finished. In addition, there are Guide, Upper Valve made of nylon, polyphenylene sulfide, polyether ether ketone and other materials, each of which has different characteristics and application scenarios.

Two, the main function

High voltage line vacuum switch tube spare parts: under the condition of -100℃ ~ +250℃, Guide, Upper Valve can be used as the spare parts of high voltage line vacuum switch tube, playing an important role.

Reduce friction and noise: the Guide, Upper Valve has smooth surface, small friction coefficient, self-lubricating, and can be used without lubricant when the friction effect is not too high, thereby reducing noise and extending service life.
