Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.
New ZL Series proportional flow control valves from HydraForce Inc. (Lincolnshire, IL) are internally pressure-compensated and operate in two directions. "The valves provide identical flow vs current ...
The 187 Series and 281 Series high-pressure directional-flow controls provide restricted flow in one direction and free flow in the other The 187 Series and 281 Series high-pressure directional-flow ...
The D03 Series of zero-leak directional valves are for use with most hydraulic pumps to maintain pressure for very long periods without replenishing the pressure supply, preventing the hydraulic ...
