Control valves are critical components in hydraulic presses, acting as the system's "traffic controllers" to manage fluid dynamics with precision. By regulating flow rate and pressure, these valves enable exact control over piston movement—dictating the speed, force, and timing of operations. This functionality is vital for applications demanding millimeter-perfect repeatability, such as metal forging or composite material molding. Beyond basic motion control, advanced valves can sequence multi-stage operations, synchronize multiple cylinders, or implement safety cutoffs. Their performance directly impacts press efficiency, product quality, and operational safety across industries from aerospace manufacturing to pharmaceutical tablet production.
Key Points Explained:
