ABB DP Series Spring Return Pneumatic Actuators – DP020SR to DP2700SR

ABB DP Series Spring Return Pneumatic Actuators are presented in this product listing as a group of thirteen model references for industrial valve automation and pneumatic actuator sourcing. The available model selections are DP020SR, DP035SR, DP050SR, DP075SR, DP110SR, DP160SR, DP255SR, DP435SR, DP665SR, DP1000SR, DP1200SR, DP1800SR and DP2700SR.

This variable product page helps industrial purchasing teams, maintenance engineers and system integrators identify the exact model required for an existing installation. Each model is listed as a separate selectable reference. Customers should verify the original equipment label and relevant technical documentation before ordering.

ABB DP Series Spring Return Pneumatic Actuators Overview

Spring return pneumatic actuators are commonly used in industrial automation systems where a pneumatic mechanism moves a valve or other mechanical device during normal operation. A spring mechanism provides movement toward a defined return position when pneumatic driving pressure is removed, subject to the actuator design and installation.

This type of actuator arrangement can be considered for automated valve systems that require a defined response to the loss of pneumatic supply. However, the required return direction and final valve position must be established by the engineering specification. A spring return actuator should not automatically be described as fail-open or fail-closed without confirming the complete valve assembly.

The ABB DP Series Spring Return Pneumatic Actuators listing groups thirteen references for purchasing convenience. The model numbers are preserved exactly as supplied, without converting them into assumed torque ratings or making claims about interchangeability.

For maintenance projects, selecting the exact replacement reference is especially important. An actuator with a similar housing or series name may have different mounting dimensions, spring characteristics, output connections or accessory requirements.

ABB DP Spring Return Pneumatic Actuator Models

The following model options can be configured as individual WooCommerce variations. Select the required model from the product options and provide the quantity when requesting a quotation.

Note: The numerical sections of these model references are not presented as verified torque, cylinder size or pressure values. All technical ratings require model-specific documentation.

How Spring Return Pneumatic Actuators Work

A spring return pneumatic actuator combines pneumatic movement with a mechanical spring return mechanism. During normal operation, the pneumatic system supplies pressure to drive movement in the required direction. When the pressure is removed, the spring mechanism can move the actuator toward its designed return position.

The final response of the connected valve depends on the actuator arrangement, mounting orientation and valve design. For example, the same general spring return concept may be applied to different valve safety requirements. Therefore, the complete actuator and valve assembly must be reviewed before defining the intended loss-of-air position.

In an industrial replacement project, the spring arrangement should be checked along with the actuator output requirements. A model with an insufficient or unsuitable return mechanism may not meet the intended application requirements.

Product Features and Important Selection Factors

Pneumatic Actuation

Pneumatic actuators use compressed air as their operating medium. The actuator must be selected for the available supply pressure and the mechanical requirements of the connected equipment. The actual operating pressure for each DP model should be verified.

Spring Return Arrangement

The spring return configuration is intended to provide a defined return movement when pneumatic pressure is unavailable. The return direction and operating characteristics are configuration-dependent and should be confirmed for each model.

Model-Specific Selection

The thirteen available references allow purchasing teams to identify the exact model requested. They should not be treated as interchangeable without confirming manufacturer specifications, mounting dimensions and the requirements of the installed valve.

Accessories and Supply Scope

Pneumatic actuator installations may involve solenoid valves, position indicators, limit switches, positioners and mounting hardware. Whether any accessory is included depends on the actual product configuration and quotation. Please specify the required supply scope.

Industrial Applications

Spring return pneumatic actuator arrangements are used in different valve automation environments. Potential applications include process valve operation, automated isolation systems and equipment requiring a defined mechanical return action.

• Oil and Gas: selected automated valve applications subject to engineering approval.
• Chemical Processing: pneumatic valve automation and replacement projects.
• Water Treatment: suitable automated flow-control and isolation equipment.
• Power Generation: process valve and auxiliary system automation.
• Industrial Utilities: maintenance and replacement of pneumatic actuator assemblies.

These are general application categories rather than confirmed approvals for each DP model. The required valve function, installation conditions and applicable technical requirements must be reviewed before selecting an actuator.

ABB DP Series Spring Return Actuator Selection Guide

Begin with the complete original model number. For example, DP020SR and DP035SR are separate references and should be selected individually. Do not substitute one model for another solely because both belong to the same product listing.

Next, confirm the required output characteristics and pneumatic supply conditions using the applicable technical documentation. The actuator must be suitable for the valve’s operating requirements, including the expected movement and mechanical resistance.

Review the mounting interface, drive connection and available installation space. Existing accessories should also be identified, particularly when replacing an actuator installed with a solenoid valve, limit switch assembly or position indicator.

Finally, confirm the required return direction and the intended valve position following loss of air. These details are important for equipment selection and must be established from the actual installation requirements.

Frequently Asked Questions

What models are included in this product listing?

This listing includes DP020SR, DP035SR, DP050SR, DP075SR, DP110SR, DP160SR, DP255SR, DP435SR, DP665SR, DP1000SR, DP1200SR, DP1800SR and DP2700SR.

What does spring return mean?

Spring return describes an actuator arrangement in which stored mechanical spring force provides movement toward a defined return position when pneumatic driving pressure is removed. The resulting valve position depends on the complete configuration.

Are all thirteen DP models interchangeable?

No interchangeability has been established. Each reference requires its own technical and mechanical compatibility checks before being selected as a replacement.

Do the model numbers indicate exact torque values?

The numerical parts of the supplied model references have not been independently verified as torque ratings. Refer to the applicable manufacturer documentation for model-specific output information.

Are solenoid valves and limit switches included?

Accessory inclusion has not been confirmed. Please specify whether you require the actuator alone or an assembly with additional control and monitoring components.

How can I request pricing for several models?

Provide a list of the required model numbers, quantities, destination country and any original equipment information. Wuhan Yuli Automation can review the request and provide model-specific quotation details.
