Automatic Shutoff Valve Decouplers, One-Handed Operating Handle

Automatic Shutoff Valve Decouplers for Single and Double Acting Systems  Decouplers are a convenient, self-contained package that includes quick connect couplings, accumulator, filters, pilot operated check valve and an over pressure relief valve.  Contains a robust pilot operated check valve with a 1:5 pilot to check ratio for proven long term reliability.  Internal 25 micron filters for added protection of the pilot operated check valve through ports A1, A2, A3, A4 and C1. Additional filtration at port B1. No filtration at remaining ports.  Integral accumulator available in three operating pressure ranges.  SAE female external ports and manifold mounting (bottom and rear) connections.  Single acting pallet circuits require 2 hoses to the Operating Handle for pressure release. For single hose systems see the Manual Shutoff Valve Decoupler.  Additional filtration available through the use of manifold mount and in-line filtration. Filter kit model # 62-5600-05 (for in-line mounting) or 62-5600-06 (for manifold mounting).

NOTE: These automatic shutoff valve decouplers and operating handle must be used with a suitable pump which includes a 4 port/3 position, P-blocked center ("A" & "B" connected to tank) directional control valve for operation of single or double acting systems. See the pump convenience package for the pump model of your choice, “Pallet Decoupler (two hose)” in section J. One automatic shutoff valve decoupler can be used to operate only one double acting or one single acting circuit. For operation of a single acting circuit, plug the decoupler outlet port "B" (as shown in the schematic).
