High power density cartridge valve

With the company’s patented VCD actuator technology, the innovative design of sleeve and spool allows for previously unattainable flow and pressure drop values. The improved efficiency, compared to regular cartridge throttle valves, enables the use of smaller nominal sizes with the same output – and thus reduces the size requirements of the control manifold blocks.

The valve is characterised by a pressure-compensated sleeve with an enlarged seat diameter and oriented windows, which for the first time almost completely uses the DIN cavity. Along with a maximum pressure of 420 bar, this results in high flow values that can increase performance in demanding applications such as die cast machines and presses.

Due to the optimised flow between the sleeve and spool, the TFP valves offers pressure differential values under ideal conditions that are only slightly higher than those of the control manifold block without valve. As with the preceding TDP series, the highly dynamic DFplus control valve with VCD actuator is used as the pilot valve. It actively positions the main poppet, and therefore operates independently to the pressure conditions in the working connections.
