Pilot Operated, Spool Type, Inversely Controlled, SAE-10 Cartridge – PDB10PZ-08/-09

SAE-10-Cartridge-PDB10PZ-08

The PDB10PZ is a pilot-operated, spool type proportional pressure relief valve.

If the pressure at port 1 exceeds the setting defined by the electrical signal, the pilot poppet opens. Then, the oil flows from behind the main spool to tank port 2. The resulting pressure differential causes the main spool to lift against the return spring. Therefore, it allows the flow from port 1 to port 2.

What’s more, as a function of the electrical signal, it is possible to steplessly change the relief pressure at port 1.

Furthermore, the control of the valve is invertible. With decreasing control current the pilot poppet closes, the main stage follows the pilot stage. It also creates a counter-pressure at port 1.

Features:

  • Reduces cavitation
  • External surfaces zinc-plated and corrosion-proof
  • A good stability across the whole pressure and flow range
  • An excellent dynamic performance
  • Hardened and ground internal valve components to ensure minimal wear and extended service life
  • The coil seals protect the solenoid system
  • Also, a low pressure drop due to CFD optimized flow path
  • And adjustable throughout flow range
