Normally closed, modulating element with pilot source from port 1

Capacity: 120 gpm480 L/min. | Cavity: T-19A
LRJA : Normally closed, modulating element with pilot source from port 1
Technical Features [ + ]

Normally closed modulating elements with an internal orifice between port 1 and port 3 can be used as a main-stage relief valve. The valve can be controlled remotely using a pilot relief or pilot solenoid valve.

  • A tuning adjustment (models configured with an L control) is available to vary the pressure drop across the compensator to increase/decrease flow within +/-25% of setting. This option is only available with the D spring option (50 psi [3,5 bar]).
  • All ports will accept 5000 psi (350 bar).
  • Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components. See the CONFIGURATION section for all options. For further details, please see the Materials of Construction page located under TECH RESOURCES.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
