Pallet Decouplers-Manual Shutoff
7250 psi maxFor Single-Acting Systems
Allows disconnecting a fixture from its power source before machining. Ideal for pallets and rotating fixtures where a fluid feed line is impractical. The manual-shutoff version is for single-acting systems only. Pallet Decoupler includes Shutoff Valve, male Quick Disconnect, Accumulator, Pressure Gauge, and Pressure-Relief Valve. This compact assembly fits easily on almost any fixture (pressure gauge can be turned horizontal for an even-lower profile). This Pallet Decoupler can be used with any of the standard Electric or Air Power Units.
Opreration
1. Remove protective cap from male Quick Disconnect on decoupler. Clean coupling components if necessary.
2. Connect hydraulic hose, with female Quick Disconnect, to the Pallet Decoupler. The power unit should be in unclamped mode (depressurized) before connection.
3. Open Shutoff Valve on decoupler to unclamp fixture.
4. After unloading and reloading the fixture, actuate power unit to clamp.
5. After pressure gauge shows proper clamping pressure, close Shutoff Valve on decoupler.
6. Switch power unit to unclamped mode.
7. Disconnect hose and replace protective cap on male Quick Disconnect. Hose can be connected to the optional safety support while not in use.
Design Considerations & Safety Precautions
Use Pallet Decouplers only with the power-workholding components, because all components must have zero leakage. The decoupler's Accumulator compensates for pressure variations due to temperature changes. This decoupler is equipped with a Pressure-Relief Valve to protect the fixture and Accumulator from extreme temperature increases.
Mounting
Fasten to fixture with two 1/4" or M6 socket-head cap screws. Mount in any position, horizontal or vertical. 1/4" BSPP port. Do not use NPT fittings.
Optional Safety Support
This support has a dummy connection for the female Quick Disconnect, for use after the hydraulic hose is disconnected from the Pallet Decoupler. An integral limit switch ensures that the fixture can be moved only if the hose has been correctly removed from the decoupler and attached to the safety support.
