In the valve design or use experience, the packing of the lift valve is mostly asbestos packing or graphite packing or PTFE V-type packing, but these kinds of packing will wear out and the gap will gradually increase as the number of valve opening and closing increases.

The ball valve is not restricted by the installation direction, and the flow direction of the medium can be arbitrary. The fluid resistance is small, and the full-bore ball valve basically has no flow resistance.

The structure of the butterfly valve is single eccentric, double eccentric, and triple eccentric. Today, we will mainly introduce the following three eccentric butterfly valves.

The difference between the single eccentric double eccentric triple eccentric butterfly valve of the center line butterfly valve is introduced as follows: 1. Centerline butterfly valve (concentric butterfly valve) The structural feature of the centerline butterfly valve is that the shaft center ......

In industrial control, the pneumatic actuator principle structure drives the air source from port A, the gear shaft rotates counterclockwise, and the valve Open the pneumatic actuator principle structure in the industrial control to drive the air source from port B, the gear shaft rotates clockwise,......

Tianjin Milestone Pump & Valve Co., Ltd teaches you how to choose a reasonable material under different environmental conditions. The correct selection of the valve material will greatly help the service life of the valve.
