ATOS DHI-0713-23 HYDRAULIC DIRECTIONAL VALVE MANIFOLD AT3

The ATOS DHI-0713-23 is a subplate-mounted directional control valve manifold from the high-performance AT3 series. It is designed for precise and reliable control of hydraulic actuators (cylinders or motors) in industrial and mobile machinery.

Decoding the Part Number: DHI-0713-23

• DHI: This signifies it is a Directional control valve, Hydraulic actuated (pilot-operated), with integrated Inductive spool position transducers (sensors). These sensors provide electrical feedback on the valve spool’s position for closed-loop control and diagnostics.

• 07: Indicates the nominal size, corresponding to NG7 / CETOP 5 (DIN 24340). This defines the port sizes, flow capacity, and mounting interface.

• 13: Specifies the spool type. In this case, “13” is a 4/3 way valve (4 ports, 3 positions) with a closed-center spool in the neutral position. When not actuated, all ports (P, T, A, B) are blocked, holding the actuator firmly in place.

• 23: Denotes the type of pilot actuation. “23” typically means dual electromagnetic pilot valves (solenoids) with a manual override. It operates on a standard 24V DC supply.

Key Features and Specifications

1. Type & Function: 4/3 (4 ports, 3 positions) closed-center, proportional directional control valve.

2. Mounting: NG7 subplate mountable (ISO 4401-05-*-0-94 standard). This allows for easy installation and removal from a hydraulic manifold block.

3. Actuation: Proportional, electrically controlled. The main spool is shifted by two proportional solenoids (pilot valves). The electrical input signal (typically 0-10V or 4-20mA) proportionally controls the spool’s displacement, which in turn proportionally regulates the flow rate and direction to the actuator. This allows for precise control of actuator speed and smooth, controlled movements.

4. Feedback: Equipped with integrated inductive position transducers (LVDT type) on the main spool. This provides continuous, real-time electrical feedback of the spool’s exact position to the controller, enabling accurate closed-loop control and machine monitoring.

5. Flow Rate: As an NG7 valve, its maximum flow capacity is typically in the range of 40-50 liters per minute (L/min), depending on system pressure. Exact ratings should be verified from the official datasheet.

6. Maximum Operating Pressure: Standard for this series is up to 350 bar.

7. Manual Override: Includes emergency/manual override plungers for testing or moving the actuator in case of power failure.
