A control valve are a device that controls the flow of liquids or gases in systems. Think of it like a faucet, when you turn the handle, you manage how much water come out. In industires, Control Valve play an important role. They help hand...
Titanium and stainless steel is two common materials for making valves. Valves are key parts in machines that control flow of liquids or gases. JUDU make these valves special, and we get lots of questions about which material are better. Both titaniu...
In liquid piping systems with high pressure differential, the control valve is not only the core of flow control but also a "battlefield" for intense fluid energy conversion. When the pressure differential across the valve is excessively la...
Under extreme operating conditions such as power plant boilers, petrochemical hydrogenation units, and supercritical systems, the coupled effects of high temperature (>350°C) and high pressure (>10 MPa) expose valve seals to multiple failure risks, i...
