The tdp series of valves is designed for controlling large flows with high dynamics. It completes hcd`s range of proportional throttle valves. Its active cartridge design ensures minimum response time and outstanding control of the main poppet, which is lifted and lowered actively by the pilot fluid. The poppet is always hydraulically entrapped to follow the command signal in an optimum manner, particularly in closed-loop systems. The tdp pilot valve utilizes the advantages of parker`s renowned dfplus voice coil technology [vcd] to provide the highest precision and dynamics. Tdp valves ah d show robust servo performance. They are available in size 3s ng 40 up to ng 100 and cover the flow spectrum beyond that of subplate mounted valves.
