1. In the closed state of the electric ball valve, there is still pressurized fluid inside the valve body. 2. Before repairing the ball valve, it is necessary to release the pressure of the pipeline and ensure that it is in an open state. The electric ball valve needs to be disconnected from its pow... read more
1. The fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length. 2. Simple structure, small size and light weight. 3. It is tight and reliable. At present, the sealing surface material of the gate valve is widely used in plastic and has good sealing p... read more
1. Threaded valve. This connection is usually processed into the taper or straight pipe thread at the inlet and outlet ends of the valve, which can be connected to the taper pipe threaded joint or pipe. Because this connection can have large leaky channels, these channels can be blocked with a seala... read more
Preparation before installation (1) The pipeline before and after the ball valve is ready. The front and rear pipes should be coaxial, and the sealing surfaces of the two flanges should be parallel. The pipeline should be able to bear the weight of the ball valve, otherwise the pipeline must be prop... read more
Possible failures and solutions of pneumatic valves. cause of issue: 1. The sealing surface leaks, and the sealing ring of the valve is trapped with debris. 2. The sealing and closing position of the valve is not consistent. 3. The flange bolts at the outlet are under pressure or not tight. 4. The p... read more
