3 M MAIN FEA ATURES Compac ct design Steering g assist bra ake valve (by using a single peda al only the correspond ding rear wheel w will brake) Only on ne valve control 4 whe eels brakes Two ind dependent feeding f acc cumulator Two ind dependent cross c split circuits c ava ailable(in ca ase of breakage of one e hose, one e rear and front brake on the e opposite site s are ope erated) Two ind dependent front f and rear circuits s available (in ( case of breakage o of one hose e, one axle is operated) o Large oil o displacem ment availa able A wide pressure se etting range is availab ble Trailer brake b valve e pilot port available Fully fre ee mountin ng position on the vehicle Mainten nance free D DESCRIP PTION The main fe T eature of the brake valve it s the capacity to o maintain essentially equalized pressure on all brakes ev ven if a little misalignments on brake b pedalls. The S6T powered brak T ke valve ne eeds a lowe er pedal fo orce than a standard master cylinder and it i can supply an a unlimite ed oil quanttity to opera ate the brakes wheel cylinders. T This valve is s being sup pplied to the e customerrs already set s accordin ng to the te echnical datta required. The brake circuit T c bleed ding is generally not requested r (raccomand ded only to o improve the t reaction tiime). All the connections are A e on the same side make m it imm mediately ad daptable on n whatever type of cab and vehicle.. A these fea All atures mak ke this valve e particularrly suitable for medium m and large e vehicles.
