The single acting cy...

In the operation of the vacuum unit, there is an indispensable step 3354 to achieve pre suction. Don’t underestimate the effect of pre pumping. It can determine the pumping speed and effect during the operation. Although the pumping speed of the manual dry oil pump of the vacuum unit is onl...

Vacuum butterfly valve refers to the butterfly valve used to open and close the valve by 90 ° rotation of the butterfly plate fixed on the rotating shaft, which is used to connect or cut off the air flow of the vacuum pumping system and the pumping pipeline. Compared with other vacuum valves of t...

Pneumatic butterfly valve can make full use of air source pressure, which is unknown to some users. This is about the pneumatic butterfly valve which is not well understood. Pneumatic butterfly valve can take away some unclean media by using air pressure. This is very effective for the improvemen...

How to equip the butterfly valve with electric actuator and how to select the type? Electric butterfly valves need to be equipped with different electric actuators according to different applications, and their wiring methods are also different, such as switching type, regulating type, signal fee...

Electric ball valve is an important valve class, which is widely used in petrochemical industry, long-distance pipeline and other fields. The closing part of the ball valve is a ball (or part of the ball) with a hole. The ball rolls with the valve stem to complete the opening or closing of the va...

It is forbidden to plug the plug-in box with electricity. After installation, the front and rear claw type chucks shall be fixed on both sides of the electric ball valve, and the screws shall be tightened. When the plug-in box with large-scale switch is installed vertically, the bottom shall be e...

In some special environments, the electric stainless steel explosion-proof ball valve will inevitably be worn during long-term use. Of course, the wear of its rotating spherical surface (inner ball) is mainly discussed here. Once this happens, it will often lead to large resistance during opening...

The stainless steel ball valve shall be completed in strict accordance with the required steps before and after assembly. The parts and components of the stainless steel ball valve shall be processed before assembly. The details are as follows: 1. According to the processing requirements, some pa...

The opening and closing of the valve are usually confirmed by the position of the handle. The handle is parallel to the pipeline to open the valve and vertical to close the valve. However, the connection between the handle and the valve stem of the ordinary ball valve is flat and square, which is...
