The Sun Hydraulics DRAXLCN (DRAXLCN) is a normally-closed, direct-acting 2-way directional cartridge with an external drain, designed as a pilot unloading valve. This component is utilized to sense pressure in one circuit and subsequently switch or unload a valve in another circuit. When the pressure at port 1 surpasses the valve's set threshold, the spool shifts to connect port 2 to port 3. The pilot area at port 1 and the spring chamber drain at port 4 are positively sealed to ensure reliable operation. The valve exhibits minimal spool leakage between work ports 2 and 3, measuring less than 20 drops per minute (1.4 cc/min). It functions equivalently to a hydraulic pressure switch without modulating. Featuring Sun Hydraulics' floating style construction, this design minimizes potential binding of internal parts due to excessive installation torque or variations in cavity/cartridge machining. The DRAXLCN fits into cavity T-21A and belongs to series 1, with a capacity of .5 gpm (2 L/min) and can handle a maximum operating pressure of up to 5000 psi (350 bar). The valve's maximum leakage upon reseat is limited to 20 drops per minute, with reseating occurring at 85% of the set pressure. The DRAXLCN has specific installation requirements: a hex size of .78 inches (22.2 mm), installation torque ranging between 30 - 35 lbf\u00b7ft (41 - 47 Nm), an internal hex size adjustment screw of .532 inches (4 mm), and a locknut hex size of .916 inches (15 mm) requiring torque between 80 - 90 lbf\u00b7in (9 -10 Nm). Weighing approximately .30 lb (.15 kg), this model includes a Viton seal kit for enhanced durability and performance in various hydraulic applications.

The normally-closed, direct-acting 2-way directional cartridge with external drain is a pilot unloading valve used to sense pressure in one circuit to switch or unload a valve in a different circuit. When pressure at port 1 exceeds the setting of the valve, the spool shifts to connect port 2 to port 3.
- The pilot area (port 1) and the spring chamber drain (port 4) are positively sealed.
- There is spool leakage between the work ports (ports 2 and 3)of less than 20 drops/min (1,4 cc/min).
- The valve is designed to not modulate and is the equivalent of a hydraulic pressure switch.
- 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.
