  • Application Considerations: Pneumatic or Electric Brakes & Clu
    What are the main differences between pneumatic brake and clutch assemblies versus electric brake and clutch assemblies? Pneumatic clutches and brakes use air cylinders to actuate and provide the normal force to transmit torque. They require 30-80 PSI of a clean compressed air...
  • Standards for Clutch/Brake Systems - Control Reliable Valves
    When operating and controlling a pneumatic clutch or brake device on a mechanical power press, it is common and most often required to use a control reliable double valve (a.k.a. double valve, dual valve, press safety valve, etc...). Double valves are designed to provide SAFETY for the operators
  • Brake Upgrades Lower Maintenance Costs (.pdf)
    The reliability maintenance team at the fine papers division of a major multinational paper producer recently discovered an alternative to the maintenance and repair aggravation they were experiencing from the pneumatic dual disk brakes on their slitter/sheeter lines and offline paper winders
  • How to Silence Squealing Pneumatic Brakes
    Because pneumatic brakes running in an industrial environment have historically been prone to generate unpleasant noise for machine operators, brake manufacturers like DFE spent significant engineering time researching methods to counter the problem of squealing brakes.
  • Electropneumatic Cylinders
    , a pneumatic brake, and an electronic controller. Continuous monitoring of rod position and velocity, combined with positive stopping action of the brake, ensures accurate positioning. The system allows up to 32 user-defined set points for each of eight programs. It interfaces to I/O devices such as computers
  • Case Story- Oil Drilling Rig
    Each brake system consists of a Dellner Brakes type SKD 2x100 hydraulic pressure applied disc brake working on an 1160 mm (45.7 in) diameter disc and a pressure intensifier system. The brakes are actuated with up to 150 bar (2,180 psi). of hydraulic pressure that is generated through a pneumatic
  • Hellenic Navy - Gun Boats
    in) or 950 mm (37.4 in) brake discs. The brakes are pressurized with a pneumatic-hydraulic pressure intensifier. Brake torque generated is approx. 200 kNm (1,770,000 lbf-in) depending on disc size and the applied pneumatic pressure. The purpose of the brakes is to quickly stop the propeller to change
  • AHTS Tug Ship, Maersk
    a pneumatic to hydraulic pressure intensifier system. The brake system develops brake torque of up to 284 kNm (2,513,600 lbf-in) per shaft.
