Modular check valves Customers can use Alfmeier modules to select combinations of non-return valves according to their connection geometries. The modular system includes a total of approx. 50 supports and 21 cases.
Mechanical switch valves Brake check valve with an additional mechanical switch.
Switches the vacuum pump via a relay depending on the pending underpressure. Direct connection to the booster or inline possible.

Sensor valves Brake check valve with relative under pressure sensor.
Gives a continuous signal to the engine control for the switching on and off of the electric vacuum pump.

Underpressure reinforcing valves Use of the venturi effect to increase the underpressure in the brake booster for vehicles that produce a low vacuum in the engine.

Products Brake Vacuum Support

We develop and produce various products for the brake system. In addition to the main task of protecting the negative pressure in the servo assistance system, our solutions also find application in the controlling of additional vacuum pumps as well as in hybrid and electric vehicles. We are an internationally qualified partner for OEMs and Tier1 customers. In addition to non-return valves, our product portfolio also includes switch and sensor controlled solutions.

As a leading manufacturer of automotive valve technology, we provide comprehensive product solutions for modern vacuum braking systems.
