The Sun Hydraulics DRAYLCV (DRAYLCV) is a normally-open, direct-acting 2-way directional cartridge with an external drain, functioning as a pilot unloading valve. This valve is adept at sensing pressure in one circuit to switch or unload a valve in another circuit. When the pressure at port 1 exceeds the set value, the spool shifts to block port 2 from port 3. It features sealed pilot area port 1 and spring chamber drain port 4, ensuring minimal spool leakage between work ports 2 and 3, recorded at less than 20 drops/min (1.4 cc/min). The DRAYLCV operates akin to a hydraulic pressure switch without modulation and utilizes Sun's floating style construction to reduce internal binding risks due to excessive installation torque or machining variations. This valve fits into cavity T-21A and belongs to Series 1 with a flow capacity of .5 gpm (2 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It has a maximum valve leakage at reseat of 20 drops/min and reseats at 85% of its setting. The hex size for the valve is .78 inches (22.2 mm), with an installation torque ranging from 30 to 35 lbf-ft (41 to 47 Nm). The adjustment screw requires an internal hex size of .532 inches (4 mm), while the locknut has a hex size of .916 inches (15 mm) with a torque requirement of 80 to 90 lbf-in (9 to 10 Nm). Weighing just .30 lb (.15 kg), the DRAYLCV is compact yet robust, suitable for applications requiring reliable pressure sensing and unloading capabilities in hydraulic systems.

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.
