Valves are control components in fluid transportation systems, used to control the flow direction, pressure, and flow rate of fluids (liquids, gases, slurries, etc.), and can achieve functions such as opening, closing, and regulating.

The basic components include: valve body (fluid channel), valve cover (connected to the valve body, sealed and supporting internal components), valve core/disc (core component for controlling flow), valve stem (connecting the valve core and operating mechanism), driving device (manual handle, handwheel, electric/pneumatic/hydraulic actuator, etc.), seals (such as gaskets, packing, to prevent...

The following key factors need to be considered: Fluid properties (medium type, temperature, pressure, corrosiveness, viscosity, particle content, etc.); Operating parameters (design pressure, design temperature, flow range); Functional requirements (fully open/fully closed, adjustable, anti backflow, etc.); Installation environment (space size, whether explosion-proof is required, manual....

Manual valves are suitable for scenarios with small diameters and low operating frequencies; When the valve diameter is large, the installation location is remote (such as high altitude/underground), and remote control or automation linkage is required (such as cooperating with PLC system), electric (electric drive) or pneumatic (compressed air drive) actuators should be equipped to improve...
