Parker Hannifin, a global leader in motion and control technologies, has introduced a two-way servo proportional valve as part of its TFP series, pioneering a new generation of cartridge valves. 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 new TFP series is the result of several years of constructive development work and intensive computer simulations. 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 uniquely high flow values that can increase performance in demanding applications such as die cast machines and presses.
