They are easy toinstall and connect, as they only require a single tube.Note: The length of the interconnecting tube must remainshort if quick response times are required.PPPSSSBleed sensorrelayBleed sensorrelayBleed sensorrelayDirectactingBallrollerCat’swhiskerSpecificationsMinimum Pre-Travel at 6 barPXFA12• ......................................................... .040 (1 mm)Maximum TravelPXFA12• ...................................................... .110 (2.8 mm)Minimum Operating Force at 90 PSI (6 bar)PXFA12• ......................................................... 11 oz.
