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

This valve is a 2-way, 2-position proportional throttle. Ports 2 and 3 are normally closed. Pilot pressure at port 1

creates a 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.

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.

Ports 1 and 4 should be limited to 500 psi (35 bar).

Pressure at port 4 directly opposes pressure at port 1.

An optional tuning adjustment (L control) is offered to vary the pilot pressure required to control flow. The tuning adjustment provides a means to manually increase

or decrease flow at a given pilot pressure. The adjustment range is 50 - 300 psi (3,5 - 20 bar), 100 psi (7 bar) Standard Setting.

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.
