Air bleed and start-up valve

Capacity: 4 - 50 gpm15 - 200 L/min. | Cavity: T-3A
NQEB : Air bleed and start-up valve
Technical Features [ + ]

Air-bleed and start-up cartridges are used to purge air trapped in the system to help reduce power requirements and facilitate pump priming during the start-up of blocked center circuits.

  • Air-bleed and start-up valves require a minimum of 4 gpm (15 L/min.) flow rate and 80 psi (5,5 bar) system pressure.
  • The valve will re-open when system pressure falls below 25 psi (1,7 bar)
  • After air has been purged, closing times vary from approximately 12 seconds at 4 gpm (15 L/min.) to 0.5 seconds at 50 gpm 200 L/min.).
  • 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.
