Product Description

This valve may be used either to unload pump pressure during periods of low demand or as a sequence valve to prevent flow
to a secondary circuit before a pre-set pressure is reached in the primary circuit.
The valve is normally closed and opened by pilot pressure on the end of an adjustable spring loaded spool. When used as an
unloading valve, the external pilot pressure diverts the pump flow through the valve to the reservoir thus allowing the pump to
idle at almost zero pressure. For sequencing, the valve is located in the secondary circuit and opened by pilot pressure from
the primary circuit.

Internal or External drain or pilot.

Adjustable pressure settings.
