Installation of the SAFEX valves should be done by a competent person that understands how to correctly setup the valves to meet the regulations. Because each machine has different joystick pilot pressures and main spool dynamics, hose burst valves cannot be purchased “pre-set” and ready to fit without adjustment.
The correct balancing of the SAFEX valve and machines main directional valve is essential and needs to be done on the machine. The opening of the SAFEX valve should lag behind the main directional valve while not affecting the machines stability and performance. This is achieved by matching each SAFEX valve to the machine on which it is installed, even machines of the same model may require individual fine tuning.
SAFEX manifolds are made from ductile iron rated to 400 Bar with nickel plating and suitable for machines with flows from 30 to 600 l/min.
