Q max. l / min (GPM) 40 (11)
P max. bar (PSI) 420 (6092)
Size 7/8-14 UNF
Description
  • Valve enables motion sequence of hydraulic actuators

  • Pressure relief function protecting the actuator against overloading and pressure peaks

  • Integrated check valve acting as an anti-cavitation valve and by-pass valve

  • Spring chambre is connected to external drainage (port 3)

  • No influence of back pressure in port 2 on cracking pressure

  • Setting can be performed during machine operation = leak free closing of adjustable element

  • Wide range of relief pressure setting up to 420 bar (6100 PSI)

  • In the standard version, the valve is zinc-coated for 520 h protection acc. to ISO 9227
