FTCAZCN - 2-way, pilot shifted, dual path, proportional throttle with position switch

Part Number: FTCAZCN

Manufacturer: Sun Hydraulics

DESCRIPTION:

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 metering passage is self-compensating.

This valve uses a dual path design, Ports 2 and 3 incorporate a double port area.

This valve incorporates a position switch to provide confirmation that the valve is closed.

  • This cartridge is supplied as a sealed, factory set unit and is not field serviceable. Any tampering will violate the product warranty.
  • Position switch is CE approved.
  • When torquing this cartridge into its cavity, a crow's foot wrench or similar will be required since the position switch precludes the use of a deep socket wrench.
  • 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.
  • An optional protective cover, with mounting hardware included, may be ordered separately. See kit number: 991-043.
  • 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.
