  • Safim Spa - Master cylinders without booster
    piston area and stroke Available on single and double circuts Step bore master cylinders These master cylinders have a step bore piston with special valves fitted internally which regulate their operation The brake fluid in the vehicle can be displaced by the larger diameter piston in large volumes but at low pressure The valves are regulated in such a way that once a pressure level has been reached at which the brakes friction surfaces are in line filling pressure the larger diameter piston is being gradually inhibited allowing the smaller diameter piston to take over Thus high brake pressures can be obtained without excessive efforts For the reasons explained above these master cylinders do not meter out a specific fluid volume but a variable one depending on the type of brake system brake clearances etc Products S6 Power Brake valves S6 Power brake valves Modular Type S6 Power brake valves E Type S6 Power brake valves Compact Type S6 Power brake valves T Type Master Priority Valves Open centre circuit Close centre circuit Master Cylinders Master cylinder without booster Master cylinder with booster Open centre booster Open centre booster with accumulator Closed centre boosters for brake fluid Closed centre booster

  • Safim Spa - Trailer Brake Valve for tractor with mechanical brakes
    must be considered in order to allow the full pedal stroke while the trailer brake valve is at the end of his stroke The valve with mechanical piloting cod 203440 have already the stroke compensator integrated into the valve The braking synchronization between the tractor and the trailer can be obtained by changing the piloting lever ratio Hydraulic piloting trough pressure emitter In this case is used a trailer brake valve with hydraulic piloting combined with a pressure emitter The pressure emitter is a device installed on the tie rod to actuates the tractor mechanical brakes and it creates an oil pressure into the pilot circuit proportional to the load received The braking synchronization between the tractor and trailer can be obtained by changing the trailer brake valve piloting ratio The piloting ratio is defined by the diameter of the pilot piston Products S6 Power Brake valves S6 Power brake valves Modular Type S6 Power brake valves E Type S6 Power brake valves Compact Type S6 Power brake valves T Type Master Priority Valves Open centre circuit Close centre circuit Master Cylinders Master cylinder without booster Master cylinder with booster Open centre booster Open centre booster with accumulator Closed centre
