Product Details

The ATOS SDHZE-A-073-L5 10S is part of the ATOS SDHZE-A family of direct-operated electrohydraulic proportional directional valves. The SDHZE-A design uses positive spool overlap and is intended for open-loop directional and flow control applications. It operates together with an external electronic driver that supplies the proportional solenoid with the required current.

The SDHZE-A series uses an ISO 4401 mounting interface and is available with different spool characteristics and electrical configurations. ATOS documentation identifies L as the linear flow characteristic and L5 as one of the available spool configurations.

Description

The ATOS SDHZE-A-073-L5 10S proportional valve is designed for applications requiring continuously adjustable hydraulic flow and directional control.

Its proportional solenoid allows the hydraulic spool position to be controlled according to an electrical command signal from a suitable external amplifier/driver. The positive-overlap spool design makes the valve suitable for open-loop control applications where proportional adjustment of actuator direction and speed is required.

The valve is commonly applicable to industrial hydraulic machinery, automation systems, machine tools, presses and other hydraulic equipment requiring controlled actuator movement.

ATOS documentation specifies SDHZE size 06 valves with a maximum pressure of 350 bar. Maximum flow depends on the specific spool and configuration; therefore, the exact flow rating for L5 should be confirmed from the applicable ordering code/datasheet before being quoted as a product-specific value.

Important: Do not select a replacement based only on the basic SDHZE-A model number. Coil option, spool configuration, connector, seals and other ordering-code details must match the original valve.

Applications

The ATOS SDHZE-A-073-L5 10S can be used for:

• Industrial hydraulic machinery

• Hydraulic automation systems

• Machine tools

• Hydraulic presses

• Manufacturing machinery

• OEM hydraulic equipment

• Material handling machinery

• Hydraulic actuator speed control

• Directional and proportional flow control

• Industrial production lines

How It Works

1. A command signal is sent to an external proportional valve driver.

2. The driver supplies controlled current to the ATOS proportional solenoid.

3. The solenoid moves the hydraulic spool proportionally.

4. Spool displacement controls hydraulic flow through the valve.

5. The connected hydraulic actuator can therefore be controlled for direction and speed.

FAQ

What is the ATOS SDHZE-A-073-L5 10S?

It is a direct-operated electrohydraulic proportional directional valve from ATOS, designed for open-loop directional and flow control.

Does the SDHZE-A have an LVDT sensor?

No. The SDHZE-A is the version without an LVDT position transducer. ATOS offers the separate SDHZE-TID family with an LVDT transducer and integrated digital driver.

Does it require an electronic amplifier?

Yes. The SDHZE-A operates with an external/off-board electronic driver that controls the proportional solenoid.

What mounting interface does it use?

The SDHZE-A uses an ISO 4401 mounting interface.

What is the maximum pressure?

For the SDHZE size 06 version, ATOS documentation specifies a maximum pressure of 350 bar. The allowable pressure at individual ports and the complete operating conditions should be checked against the applicable datasheet.

What does L5 mean?

In the ATOS ordering system, L identifies the linear spool characteristic, while 5 identifies a particular spool type/size configuration. The exact hydraulic flow characteristics should be verified from the applicable ATOS technical table.

Can I replace another proportional valve with SDHZE-A-073-L5 10S?

Not automatically. The mounting interface, spool configuration, flow requirement, pressure, coil, connector, electrical driver and hydraulic circuit must all be checked before replacement.

Related ATOS Models

• SDKZE-A series

• SDHZE-TID

• SDKZE-TID

• SDPZE-A

The SDHZE-A is the size 06 family, while SDKZE-A is the size 10 family.

Alternative Models

For applications requiring integrated electronics and position feedback, the ATOS SDHZE-TID family may be considered. It incorporates an LVDT position transducer and on-board digital driver, making it a different configuration from SDHZE-A.

Alternative selection must be confirmed according to the hydraulic circuit, electrical command signal, flow requirement and existing valve configuration.
