In valve engineering, the Cv value (Flow Coefficient) of the control valve refers to the volume flow rate or mass flow rate of the pipe medium through the valve per unit time and under the test con...
When the valve is fully open, a sealing device that prevents the medium from leaking to the stuffing box is called the upper sealing device.
When the gate valve, globe valve and throttle valve are ...
Valve foundation
1. The basic parameters of the valve are: nominal pressure PN and nominal diameter DN
2. Basic function of the valve: cut off the connected medium, adjust the flow rate, and change...
Manufactured valves must undergo various performance tests, the most important of which is pressure testing. Pressure test is to test whether the pressure value that the valve can withstand meets t...
Rubber seated butterfly valve is a popular and widely used type of butterfly valve in various industries. It is known for its reliable performance and versatile applications. There are many types o...
In the ‘steel jungle’ of industrial pipelines, valves act as silent water workers, controlling the flow of fluids. However, they often ‘die young,’ which is truly regrettabl...
