The Sun Hydraulics DRAYLAV (Material Number: DRAYLAV) is a normally open, direct-acting 2-way directional cartridge with an external drain, functioning 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 block port 2 from port 3. The pilot area at port 1 and the spring chamber drain at port 4 are positively sealed, ensuring minimal leakage between work ports 2 and 3, with a maximum leakage rate of less than 20 drops per minute (1.4 cc/min). This valve acts as a hydraulic pressure switch without modulation capabilities. The DRAYLAV model incorporates Sun's floating style construction, reducing the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. It fits into cavity T-21A and belongs to Series 1 with a capacity of .5 gpm (2 L/min). The maximum operating pressure for this valve is rated at 5000 psi (350 bar), with a reseat capability of 85% of the setting. The valve hex size measures .78 inches (22.2 mm), while installation torque ranges between 30 - 35 lbf ft (41 - 47 Nm). The adjustment screw features an internal hex size of .156 inches (4 mm), and the locknut has a hex size of .5625 inches (15 mm) with a torque range of 80 - 90 lbf in (9 -10 Nm). The model weighs approximately .30 lb (.15 kg) and utilizes Viton seal kit number: 990021006 for maintenance purposes.

The normally-open, 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 block port 2 from 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.
