What is a ball valve? Ball valve is a kind of liquid level measurement and control product. It is composed of several main parts such as valve body, piston, connecting rod and floating ball. The principle of lever is applied to make the valve unblocked or blocked. In the...
Ball valve installation: It must be confirmed that the pipeline and valve have been cleaned before operation. The actuator operation of the valve drives the stem to rotate according to the input signal: when the valve rotates 1 / 4 turn (900) in the forward direction, the valve is...
Function of ball valve: The opening and closing part of the ball valve is a round ball with holes. The ball core is used to rotate 0-90 ° around the axis of the valve rod, so as to open or close the valve. Ball valve has many functions. It...
There are many kinds of ball valves. According to the different structure, connection method and valve body material, the corresponding working conditions are different. However, in all types of ball valves, the sealing forms are only divided into soft sealing and hard sealing. Due to the different sealing materials...
The electric ball valve has the advantages of small size, light weight, small installation size, small driving torque, simple operation, agility, etc. it can be opened and closed quickly only by rotating 90 °, and has good flow regulation effect and sealing characteristics. In the application scope of large...
The working principle of electric flange ball valve is to achieve the opening and closing of the valve by driving the power supply and rotating the valve rod. It has the characteristics of light switch, small volume, reliable sealing, simple structure, convenient maintenance, etc. because the sealing surface and...
Electric ball valve is a kind of valve used to control pipeline medium and realize remote control. It is an important equipment in industrial automation control system at present. Including pneumatic ball valve, and other valves in the use process can not be continuous. After storage or use for...
Before installation of pneumatic ball valve: Ensure that the installation position of the pneumatic ball valve is at the coaxial position, the two flanges on the pipeline shall be kept parallel, and confirm that the pipeline can bear the weight of the pneumatic ball valve itself. If it is...
The electric ball valve is mainly composed of electric actuator and ball valve. The plug body is a ball with 90 degree rotation action. The electric ball valve is not only a good product for throttling, cutting off, on-off and turning, but also the first choice in the flow...
O-ball valve structure: The valve body of the o-ball valve is equipped with a ball with a middle through-hole, and a through-hole with the diameter equal to the pipe diameter is opened on the ball. When the ball is fully opened, it is an open valve with large capacity,...
