FEATURES

  • Flow capabilities exceed competitive designs
  • Externally adjustable for precise pressure settings
  • Rugged cast iron construction
  • Automotive style pedal feedback

2100 Series Values

The valves are available in single circuit (2101) and parallel circuit (2102) configurations and are capable of modulating output pressures to a maximum of 3,500 psi (24,133 kPa).

FEATURES

  • Spool sleeve design allows for easy serviceability
  • Large supply and return ports provide high flow capabilities
  • Externally adjustable to provide precise pressure settings
  • Standard pilot apply (optional on the 2101 series)
  • A number of pedal and switch options are available

Hydraulic Adjusters

Carlisle’s automatic adjusters are used for in-line adjustment of high-displacement hydraulic brakes, such as wet brakes. The adjuster functions to maintain running clearance at each brake application. In drum brake applications, the adjuster also compensates for clearance reduction due to thermal contraction of the brake.

FEATURES

  • Rugged cast iron construction
  • Available in single and dual circuit configurations
  • Capacities range from 3.5 to 15 CU in
  • Piston replacement kits available

Standard & Boosted Master Cylinders
