Fike Corporation was established since 1945, USA
The headquarter is places at Blue Springs, Missouri. From the beginning company was focused on implementation of industrial explosion and fire protection systems, based on gained experience.
Since that time, many branches have been launched all over the world (Belgium, France, Germany, Italy, Great Britain, Spain, Canada, Japan, Brazil, India, Bahrain, Malaysia.
In Czech Republic, official representative of Fike is VALWO s.r.o.
The most recognized Fike products are rupture panels and bursting disc (explosion offloading), active protection systems against
explosion (HRD/SRD) and passive – such as flame quenchers (flameless offloading) or other modern solutions as pinch valves or fast
activating valves. Common feature of all the equipment is, beside increasing the level of safety, significant increase of economic aspects – lowering the exploitation costs.
