Design and manufacture hydraulic valves for your control application.

Features
  • Feeding unit diverts flow directly in steering systems and working hydraulic systems at low pressure drop, which is a good substitute for pilot pump.
  • Pilot valve supply unit is suitable for machinery without pilot pump, energy saving.
  • Pilot volve supply unit with accumulator provides an instantaneous flow rate up to 40 L/min, much higher than that supplied by a pilot pump (10 L/min), thus improving flexibility and efficiency.
  • Hydraulic valve is equipped with four solenoid valves to direct oil flow through P and F Port (inlet and outlet).
Applications
  • Loader
  • Bulldozer
  • Hoisting machinery
  • Agricultural machinery
  • Material handling machinery
