Due to their design principle, directional seated valves offer a high potential for energy savings compared to directional spool valves. So it makes sense to optimize the entire production process of these seated valves accordingly. HAWE Hydraulik uses the GHG protocol for the evaluation of the Product Carbon Footprint (PCF) and currently considers the cycle from the procurement of all materials to delivery to the customer. The high depth of added value in the HAWE production plants, the associated short transport routes plus a product design that generates little material waste in production, contribute positively to this.
