L Series Modular Stacking Valve System

The "L" Series is a manifold system made up of modular valve blocks which are stacked together and fixed with tie rods.
 
FEATURES
Truly Modular
Modular design allows a machine manufacturer to offer multiple options on a single machine without having to stock or machine separate manifolds.
Compact
Excellent flow and pressure characteristics in a space-saving package.
High Pressure
Most control modules are rated for 5000 psi.
Time Saving Solutions
Modular design affords simple to complicated circuit solutions, eliminating the time and cost needed to design and machine a manifold or hard-pipe in-line controls.
Wide Array of Control Options
Pressure controls, directional controls and combination modules are offered.
  • Pressure Control Modules
    • Direct acting and hydraulically dampened for smooth, quiet control.
  • Directional Control Modules
    • Solenoid and check valves are of a metal to metal seat design, providing leak-free performance.
    • Solenoid coils are rated for 100% continuous duty.
FUNCTION
The HYDAC "L" Series Modular Stacking Valve System offers a multitude of control modules that are stacked in series and fixed with two tie rods to form an integrated manifold. The manifolds may then be mounted as stand-alone packages, or as "on-board" controls for HYDAC "CA" or "HP" power units.
There are three general types of modules which are used in building a manifold: Base Modules, Control Modules, and End Modules.
The base module can be piped with SAE O-ring ports for remote mounting or flange-mounted to a HYDAC power unit. Control modules include a wide selection of both pressure and solenoid control valves. The end modules cap the assembly and can include other hydraulic accessory components such as pressure switches and accumulators.
Features, such as 100% continuous-duty coils and leak-free solenoid and check valves, make the "L" Series ideal for extended clamping and load holding applications.
