NOTE: DATA MAY VARY BY CONFIGURATION. SEE CONFIGURATION SECTION.
This valve is a 2-way, 2-position proportional throttle. Pilot pressure at port 1 opposes the spring and creates a
variable metering orifice between port 2 and 3 that is proportional to the pressure at 1. The force balance of the flow
forces, spring and pilot pressure results in a degree of partial self-compensation as the load pressure changes.
Pressure at port 4 directly opposes pressure at port 1.
The valve uses a dual-path design. Ports 2 and 3 incorporate a double-port area.

TECHNICAL FEATURES
These valves may be pressure compensated by an external, modulating, logic element. Use LR_C-XHN for a bypass circuit or LP_C-XHN for a restrictive circuit.
The valve provides a degree of self-compensation and may be used as a flow control. To increase the accuracy of flow control, an external, modulating, logic
element can be used to maintain a constant flow over a wider range of flows and pressures. See performance curves for additional information.
The optional L control is a stroke adjustment that limits maximum flow.
Ports 1 and 4 should be limited to 500 psi (35 bar).
Pressure at port 4 directly opposes pressure at port 1.
Accurate pressure compensated control requires that a constant pressure differential be maintained across the valve.
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.
