The Integrated Pilot Head (IPH)

Cities are popping up like mushrooms, and many homeowners quite fancy a garage or a proper garden with a pond: demand for construction machinery and vehicles is on the rise. But lot sizes are shrinking – and thus the space available to carry out the necessary work. Small vehicles and machines can meet these requirements, making them much more practical. Picking up on this trend, Thomas has developed the Integrated Pilot Head (IPH), the only one of its kind on the market. Specifically, it is a proportional pressure-reducing valve that enables OEMs to build machinery that is even more compact:

Integrated Pilot Head (IPH) – what’s that?

The Integrated Pilot Head (IPH) is a 3/2 proportional pressure-reducing valve that is fitted inside construction machinery in order to control the flow rate of its main valves precisely and reliably. With its three connectors (labelled “P,” “A,” and “T” for pump, work (“Arbeit”), and tank), the IPH can be connected either to the distributor block via a sealed interface or directly to the main valve. Thomas developed the IPH for a leading German manufacturer of mobile hydraulic systems as a 25-bar version but can offer additional pressure levels at its customers’ request. Compared with other products on the market, the IPH boasts unbeatable technologies and benefits that no other competitor can offer.

Top 5 advantages of the IPH

The proportional pressure-reducing valve houses all the hydraulic functions inside the solenoid so does not need a valve sleeve on top. All the hydraulic connections are protected by an integrated filter element, while a specially heat-treated valve gate ensures optimum performance when using contaminated oil.

The IPH experiences minimal hysteresis due to the very low friction between the moving parts. This allows the pressure and flow rate to be controlled precisely, improving the efficiency and performance of the construction machinery. The IPH also responds very quickly to commands and sends direct feedback to the user.

The flat connection profile obviates the need to push the valve into its mounting hole – a laborious and time-consuming process – and eliminates the risk of the valve part getting stuck.

Omitting the valve sleeve means that no holes need to be drilled for the valve, allowing OEMs to reduce the size or height of their distributor block or main valve. This saves on material and machining costs.

The minimal amount of internal space allows the valve to bleed extremely quickly. No special rinsing or bleeding routines are required, enabling machinery to be commissioned even faster.
