Valve Type: 24VDC 2-Position 3-Port Normally Open

Recommended to run a continuously connected or single hose supply decoupled system where, the pressurized time exceeds the unpressurized time. Operator interface is by remote pendant or can be wired into a machine controller.

NOTE: Should not be used with palletized systems as the valve is energized to unclamp. The unclamped time will be excessive, causing the valve to run hot.

Valve Type: 24VDC 2-Position 3-Port Normally Closed "Dump Pump"

Single Acting Decoupled Systems Valve installed with a control pendant to power systems using the Self-closing Decoupler and Tombstone Top Plates. Commonly called a "dump pump" and uses a momentary contact pendant switch. When preset pressure is reached the control valve automatically shifts and dumps pressure back to tank. Operator interface is by remote pendant or can be wired into a machine controller.

Single Acting Live systems. Use with Manual Pallet Decouplers, Tombstone Top Plates and Self-Closing (single hose) Decouplers Operator interface is by remote pendant or can be wired into a machine controller.

NOTE all decoupled valves are de-energized when not in use to avoid heat build up between cycles.

Warning: The use of spool valves invalidates the warranty on VektorFlo® pumps.

NOTE: Contact factory for custom pump configurations.
NOTE: Voltages listed are input to control box for pump motor. All solenoid valves use 24 VDC control voltage supplied by the transformer internal to the pump control box. Wiring of control valves supplied with pump is not required.
NOTE: Solenoid valves configurations are supplied with one valve control pendant with a 6 ft. cable. For additional pendants order from the chart.
NOTE: See pump manual to calculate the required electrical service for your specific application.
NOTE: All 115VAC single phase pumps require a 20 AMP dedicated service electrical connection for proper operation and service life.
