Technical features

This is a vent-to-shift, 2-position, diverter valve that is normally closed. 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 with ports 2 and 4.

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 bypass divider/combiner valves in a limited-slip tractive circuit. Closed, the oil must go through the divider/combiner valves. Open, there is a large path around the divider/combiner valves for efficient high speed operation.
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.
