Looking at the future

The world is changing fast and Bitron is working to be part of this change. We want to give a concrete help to our customers during the transition into the e-mobility era.  To achieve our goal, we have managed to optimize weights, materials and power consumption of our components.

Coils winding

Technologies 

In Bitron every detail values. For this reason, we have decided to internalize all key core technologies to develop and produce our products. In this way, we are sure to have control of all processes of our components, from the idea to it's realization: 

 

 

Automatic coil winding

Injection molding department with several molding machines (horizontal and vertical), robots & automation for metal insert overmolding

CAD/CAE systems for design, simulation & digital mock up 

Laser welding to join plastic component with robust and waterproof connection

Laboratory testing equipment for product development and validation

Products
Air solenoid valves

Description

One of our most diversified family. The protagonist is the air, core element for this specific type of valves. It includes clean air, vacuum, gasoline vapors, dirty air from carter among others. The main applications are by-pass EGR, waste-gate, dump valve, TGV, purge, cold start, Carter purge. We keep investigating this branch of systems to discover new ways to reduce gasoline consumption in Hybrid cars. 

 

Key features: 

  • 3/2 or 2/2 ways
