Whitepaper: "Directional seated valves - undervalued potential in the design of hydraulic controls"


Directional spool valves are a common component in control systems. The technology is well-known and tried and tested. This white paper intends to demonstrate specifically that directional seated valves can handle the same control tasks while at the same time offering multiple opportunities to cut costs. Switching to them holds great appeal, particularly in view of the pressure to reduce energy consumption, to minimise costs-over-life and to optimally design the required package space.
