Product Overview
▔▔The Atos DHZE-A-073 is a high-performance, direct-operated, digital proportional directional valve designed for precise direction and speed control of fluid flow in modern hydraulic systems. Operating without integral dynamic position feedback, the DHZE series combines standard industrial performance with advanced digital electronics, offering exceptional repeatability, durability, and seamless system integration.
Key Advantages
▔▔-
Digital Electronics Integration: Features factory-preset digital drivers that ensure optimal performance, linear response, and reduced wiring setup.
Compact & Robust Design: Built according to ISO 4401 size 06 standard, ensuring universal interchangeability and easy installation.
High Flow & Pressure Ratings: Capable of handling operating pressures up to 350 bar and flow rates optimized for demanding industrial automation.
Precision Control: Delivers smooth acceleration, deceleration, and high-frequency positioning for hydraulic actuators.
Rugged Construction: Zinc-plated or phosphated coils and bodies provide superior corrosion resistance in harsh operational environments.

FAQ
▔▔Q1: What does the "-A" designation signify in the Atos DHZE-A-073 model code?
A: The "-A" suffix indicates that the valve is equipped with integrated digital electronics (driver) mounted directly on the valve, requiring no external driver card for basic operation.
Q2: What is the main difference between the DHZE-A-071 and DHZE-A-073 models?
A: The main difference lies in the neutral center spool position:
DHZE-A-071: In the neutral position, all ports (P, A, B, T) are blocked.
DHZE-A-073: In the neutral position, port P is blocked, while work ports A and B are vented/connected to tank port T.
