Directional Valve Group ECO 80
Function
Safety
It is the customer's responsibility to decide on the required degree of safety for the system. All marks and
all types of directional control and proportional valves can fail and cause serious damage. It is therefore
important to analyze all aspects of the application. Proportional valves are used in many different
operating conditions and applications; therefore the manufacturer of the application is responsible for
making the final selection of the products and assuring that all performance, safety and warning
requirements of the application are met.
Cost-free repairs, as mentioned in Danfoss General Conditions of Sale, are carried out only at Danfoss or
at service shops authorized by Danfoss.
