Technical specifications

This valve is a 2-way, 2-position proportional throttle. Ports 2 and 3 are normally closed. 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.

  • 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.

  • U6N ISO 07: Throttle, low capacity
  • U6S ISO 05: Throttle, low capacity
  • U6X Throttle, low capacity
  • U7B Throttle, low capacity with bypass
  • When installed in Sun's standard T-52A line mount manifold, plug unused ports and expect higher pressure drops.
