The Sun Hydraulics DRAXLAV (DRAXLAV) is a normally closed, direct-acting 2-way directional cartridge with an external drain that functions as a pilot unloading valve. It is designed to sense pressure in one circuit and 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 securely sealed, minimizing leakage between work ports 2 and 3 to less than 20 drops per minute (1.4 cc/min). This valve acts similarly to a hydraulic pressure switch without modulation capabilities. The DRAXLAV model incorporates Sun's floating style construction, which minimizes potential binding of internal parts due to excessive installation torque or variations in cavity/cartridge machining. It fits into cavity T-21A and belongs to Series 1, offering a capacity of .5 gpm (2 L/min) and a maximum operating pressure of up to 5000 psi (350 bar). The valve's reseat capability is set at 85% of its setting, with a maximum leakage rate upon reseat of 20 drops per minute. For installation, the valve requires a hex size of .78 inches (22.2 mm) and an installation torque between 30-35 lbf-ft (41-47 Nm). The adjustment screw has an internal hex size of .532 inches (4 mm), while the locknut requires a hex size of .916 inches (15 mm) with a torque specification of 80-90 lbf-in (9-10 Nm). The model weighs approximately .30 lb (.15 kg) and uses Viton seal kits for optimal performance.

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.
