NOTE: DATA MAY VARY BY CONFIGURATION. SEE CONFIGURATION SECTION.

This vent-to-shift diverter valve is a 2-position, 3-way cartridge that is normally open from port 3 to port 4. When

port 1 is vented, the pressure differential between port 3 and port 1 exceeds the spring force causing the valve to

shift, thereby connecting port 3 to port 2.

TECHNICAL FEATURES

This valve is not bistable; it is capable of modulating between the two positions shown.

Vent flow out of port 1 is pressure compensated and is listed in Technical Data.

There must be a pressure source at port 3, relative to port 1, to shift the valve.

One application of this valve is to be used in pairs to select between 2 motors or pumps.

One pilot valve may be used to vent multiple diverter valves if blocking checks are used at port 1 of each diverter. If blocking checks are not used there will be

interaction between high and low pressure legs of the circuit.

The vent-to-shift function is self cleaning and therefore insensitive to contamination.

Hardened spool and sleeve provide consistent and low spool leakage rates and excellent wear characteristics.

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.
