Description

Pilot-Operated Check Valve. Check valves operate on slight differential pressure. Free flow is permitted in the direction of the arrow, positive check in the opposite direction. Reverse flow can be achieved by reaching the required pilot pressure at port (3).

Features and Benefits
  • For hydraulic applications only
  • Air pilot valves have secondary seal on pilot piston stem.
  • A vent hole in the body between the piston seal and stem seal prevents mixing of pilot media and the system media
