How to repair the French electric high vacuum butterfly valve that is tight? 1、 The control valve is a terminal actuator in the automatic control system, which adjusts the production process by receiving control signals. The control valve has the functions of high stability, low price, fire and explosion prevention, and can be used together with pneumatic and electric regulating instruments, with high degree of automation.
、 When the pneumatic ball valve is installed, the installation position can be determined by the position of the structure. It must be manually operated, and the tightness of the valve must be ensured to ensure that the valve on the ground is upward without any inclination, which will cause friction between the valve and the internal metal during operation, The fire core generated in this way will also cause more dangerous operational safety impact. It is also important to note that the installation method of the valve should not be inverted, that is, the installation of the hand wheel should not be downward, which will also affect the service life of the valve.
