In the building of mechanical sequences, such as the sequence of extensions of a telescopic cylinder, the FCM end stroke valves represent an essential component. In rest position the valves interrupt the oil flow from port 1 to port 2. In the same direction, thanks to the poppet, they guarantee the pressure seal. Pressing the pushbutton allows free flow in both directions. FCM valves can also be used as mechanical unloading valves. The external body is made of high-strength steel and is protected against oxidation with zinc plating treatment. It is available as optional a zinc/nickel treatment in order to increase the resistance to corrosion in applications exposed to particular atmospheric conditions, such as maritime applications. The pushbutton is made of stainless steel to guarantee long life. Depending on the size, the FCM valves can work with flow rates up to 60 lpm(16 gpm) and pressures up to 350 bar (5075 PSI).
