DG5V-7-6C-T-P7-H-80-JA

The DG5V-7-6C-T-P7-H-80-JA valve is produced by Vickers within the DG5 Two-Stage Directional Valves series for hydraulic automation systems that require precise directional control of high-pressure fluid. It uses spool type 6, which keeps port P closed while ports A and B are connected to T when centered, allowing controlled depressurization during standby. The unit handles a maximum flow of 300 L/min (80 USgpm) so it can supply large cylinders and motors without excessive pressure loss. Operating pressure in ports P, A, B, and X may reach 350 bar (5000 psi), while the T port is limited to 210 bar (3045 psi) to protect return components. Pilot pressure can also be applied up to 350 bar (5000 psi) to ensure secure spool shifting under load. A control volume of 7.28 cm³ (0.44 in³) between chambers C and e defines the pilot oil requirement for each stroke. The spring-centered direct-current version weighs 9.1 kg (20.0 lb). Environmental protection is rated at IP65, guarding internal parts against dust and low-pressure water.

Electrical actuation is provided by a 24 V DC solenoid, enabling direct connection to common machine controllers. The coil draws 30 W, allowing compact power supplies to support continuous energization. Winding insulation conforms to Class H, and the assembly is encapsulated to Class F, giving the coil elevated thermal endurance. A duty cycle of 100 % ED permits uninterrupted holding without premature insulation fatigue. Reliable operation continues when supply voltage falls to 90 % of nominal, which helps the system ride through brief undervoltage events. The valve remains functional at ambient temperatures down to −20 °C (−4 °F), making it suitable for cold-storage or outdoor equipment. When the coil is energized at 110 % of rated voltage, allowable enclosure temperature rises to 70 °C (158 °F), establishing the upper thermal limit for cabinet design. These electrical and thermal limits complement the hydraulic capabilities described earlier and define safe operating conditions for the DG5V-7-6C-T-P7-H-80-JA in automated fluid-power circuits.
