BorgWarner Logo

Many of the components needed to design and build fuel systems to meet upcoming EPA regulations are new to the marine industry. Proven automotive versions of these components have been in use for decades. Rather than recreating these components, we have elected to partner with one of the premier brands in advanced automotive fuel systems. This allows us to offer boat builders and tank manufacturers the components needed to comply with upcoming environmental regulations, all with the benefit of automotive quality standards. Perko is the exclusive distributor of BorgWarner marine canisters.

Our partner, BorgWarner, has been manufacturing carbon canisters for over 40 years. They supply many of the world’s largest automobile manufacturers and have attained the coveted Q1 quality rating from Ford. By partnering with BorgWarner we are able to offer products that have been tested to automotive standards for safety and reliability.

    Raval was founded in 2000 as the development and marketing facility for venting valves following 5 years of valve production by its parent company, Raviv ACS Ltd. For the first decade of its existence, the company was based at Kibbutz Revivim in the Negev Desert adjacent to Raviv which specializes in plastic injection molding. In 2002, as the company extended its activities in the European automotive market, a facility in Luxembourg was established.

    In recognition of the burgeoning East Asian automotive industry, a plant was established in Shanghai in 2007. In April 2007 an IPO for Raval was launched on the Tel Aviv stock market and as such, Raval assumed full control of the production facility for venting valves at Kibbutz Revivim. In 2002, as the company extended its activities in the European automotive market, a facility in Luxembourg was established.


    With the continuous expansion of our development, production and sales, the facility at Kibbutz Revivim could no longer offer sufficient space so in 2010 Raval moved to its present location in a suitable building in the Emek Sarah Industrial Zone of Israel.
