Pierburg GmbH develops 2/2-way coolant valve for both ICE and electric vehicles

Automotive supplier Rheinmetall Automotive, a member of the Technology Group Rheinmetall, is systematically expanding its product portfolio in the direction of future driveline systems without neglecting its traditional combustion engine business.

Neuss-based Pierburg GmbH, a part of Rheinmetall Automotive AG, has developed an innovative 2/2-way (2 connections, 2 switching positions for 2 flow directions) coolant valve for which it has now received its premier major European order from a German premium OEM. The hallmark of these new coolant valves is that they will be used both in vehicles with conventional combustion engines­ and in battery-powered vehicles.

The valves developed and produced at the Neuss site will go into series production in the customer’s vehicles as from 2021. The total order volume is around €50 million.

Pierburg will supply valves for a complete engine series of this OEM including 3-, 4- and 6-cylinder gasoline engines where the valve will control the coolant flow to the degas bottle and to the transmission. On the new battery-powered models of this premium manufacturer, the same valves are also used to control the cooling of the high-voltage system.

The Neuss-based specialist for solenoid valves now has a comprehensive modular coolant valve system which includes both 3/2-way and 2/2-way valves with various flow rates in both currentless open or closed design.
