Valve Automation Solutions

A Complete Guide to Automated Valve Control for Industrial Applications

Industry Insight | SDTORK Actuators

Modern industrial plants depend on accurate and reliable flow control. Whether the process involves water, steam, chemicals, oil, gas, air or other industrial media, valves regulate the movement of fluids and gases throughout the system.

As industrial operations become increasingly automated, manual valve operation is being replaced or supplemented by valve automation solutions that provide controlled, repeatable and remote operation. At the centre of many automated valve systems is an electric actuator, which converts electrical energy into controlled mechanical movement.

For industries looking for reliable valve automation solutions in India, selecting the right actuator and control configuration is an important engineering decision. The solution must match the valve type, torque or thrust requirement, operating environment, duty cycle and control system.

What Are Valve Automation Solutions?

Valve automation refers to the use of an actuator and associated control equipment to operate an industrial valve automatically.

Instead of manually opening or closing a valve, an automated system allows the valve to be operated through an electric, pneumatic, hydraulic or other actuation mechanism.

A typical automated valve system can include:

• Industrial valve

• Electric actuator

• Gear mechanism, where required

• Control panel or local control station

• Position feedback

• Limit and torque switches

• Power supply

• PLC, DCS or SCADA interface

• Communication and monitoring equipment

The actual configuration depends on the valve, process requirements and required level of automation.

A reliable industrial valve automation system therefore needs to be designed as a complete solution rather than simply selecting an actuator from a catalogue.

Why Do Industries Need Valve Automation?

Industrial processes increasingly require reliable and repeatable valve operation. Manual operation can become difficult when valves are located in remote areas, installed in demanding environments or operated frequently.

Valve automation can support:

Remote Operation

Automated valves can be controlled from a designated location, reducing the need for operators to access individual valves.

Process Control

Automated operation can provide consistent opening, closing or positioning according to the process requirement.

Operational Efficiency

Automation can reduce repetitive manual intervention and improve coordination between different process systems.

Position Monitoring

Depending on the actuator configuration, position feedback can provide information about valve status to operators or control systems.

Reliable Operation

A correctly selected actuator can provide repeatable movement within its specified operating conditions.

These advantages make valve automation an important part of modern industrial flow-control systems.

Types of Valve Automation Solutions

Different valve designs require different forms of movement. This is why actuator selection must begin with understanding the valve.

The three major electric actuation categories are quarter-turn, multi-turn and linear actuation.

Quarter-Turn Valve Automation

Quarter-turn actuators provide rotary movement for valves and dampers that require limited angular rotation.

They are commonly used with suitable:

• Butterfly valves

• Ball valves

• Plug valves

• HVAC and industrial dampers

SDTORK's Quarter-Turn Electric Actuators are designed for rotary applications and are available in different configurations for industrial environments.

Quarter-turn actuator selection should consider the valve's operating torque, duty requirements, operating time and control method.

Multi-Turn Valve Automation

Multi-turn actuators are designed for valves that require multiple rotations to complete their travel.

Typical applications include suitable:

• Gate valves

• Globe valves

• Multi-turn valve systems

SDTORK's range includes the SD-3000 Series Multi-Turn Electric Actuators, developed for multi-turn valve applications. The series is available in different torque and control configurations and can be used in industries such as water, marine, energy, chemical, power, HVAC and general process applications.

Multi-turn actuator selection requires careful consideration of valve torque, thrust, travel, operating speed and duty cycle.

Linear Valve Automation

Some industrial valves and process equipment require linear rather than rotary movement.

Linear electric actuators produce controlled linear motion and can be applied to suitable:

• Globe valves

• Gate valves

• Control valves

• Dosing equipment

• Damper applications

SDTORK's Linear Electric Actuators include configurations for applications requiring controlled linear movement.

For higher-thrust applications, the SD-3000 + LTU Series provides a multi-turn actuator combined with a linear transmission unit for suitable valve applications.

Electric Valve Automation vs Manual Operation

Manual valves can be suitable where operation is infrequent and the valve is easily accessible.

Automated valve solutions become more useful where there is a requirement for frequent or remote operation.

They can support:

Frequent Operation
Repeated manual operation can require significant operator time.

Remote Operation
Valves installed in difficult-to-access locations can be operated from a designated control point.

Modulating Control
Some processes require valves to operate at intermediate positions rather than only fully open or fully closed.

Control-System Integration
Automated valves can form part of wider plant automation systems.

Position Feedback
Actuator feedback can help operators and control systems understand valve position and operating status.

The right approach depends on the process and project requirements.

Important Factors When Selecting Valve Automation Solutions

Selecting an actuator should begin with understanding the complete application.

Valve Type

The actuator must provide the movement required by the valve.

A butterfly valve typically requires quarter-turn movement, while a gate valve may require multi-turn operation.

Torque or Thrust

Rotary actuator applications are generally evaluated using torque, while linear applications require thrust.

The required output should be based on the valve manufacturer's specifications and actual operating conditions.

Duty Cycle

The frequency and duration of operation influence actuator selection.

A frequently operated modulating application can have different requirements from an occasional open-close application.

Operating Environment

Industrial installations can expose actuators to:

• Dust

• Moisture

• Temperature variations

• Corrosive conditions

• Outdoor environments

• Potentially hazardous atmospheres

The actuator enclosure and protection configuration must be appropriate for the installation.

Control Method

The required control method should also be established before selecting the actuator.

Depending on the application, requirements may include:

• Local operation

• Remote operation

• On-off control

• Inching

• Modulating control

• Position feedback

• PLC integration

• SCADA integration

The actuator should be compatible with the intended control architecture.

Smart Valve Automation and Industrial Control Systems

Valve automation is increasingly becoming part of larger industrial control systems.

Modern facilities may use PLC, DCS and SCADA platforms to monitor and control equipment throughout the plant.

An appropriately configured electric actuator can act as the field-level interface between the control system and the physical valve.

Depending on the actuator and application, features can include position feedback, local control, electronic positioners and other control accessories.

This means the actuator does more than operate the valve. It can also provide useful operating information to the wider automation system.

Weatherproof and Flameproof Valve Automation

Different industrial environments require different actuator protection configurations.

Weatherproof Actuators

Weatherproof actuators are designed for appropriate applications where protection from environmental exposure such as dust and moisture is required.

SDTORK's product range includes weatherproof electric actuators in quarter-turn and multi-turn configurations. For example, the SD-3000 Series is available with IP65 protection, with higher protection configurations available within the range.

Flameproof Actuators

Applications involving potentially hazardous atmospheres require appropriately specified and certified equipment.

SDTORK provides flameproof electric actuator configurations for suitable hazardous-area applications. Selection should always be based on the hazardous-area classification, applicable certification and project specifications.

The Importance of Correct Actuator Sizing

One of the most important parts of valve automation is correct actuator sizing.

An actuator that is too small may not generate sufficient output to operate the valve reliably. Oversizing can also increase system cost and may not be appropriate for the application's operating characteristics.

Important selection inputs can include:

• Valve size

• Valve type

• Operating torque

• Breakaway torque

• Seating torque

• Thrust

• Valve travel

• Operating time

• Process pressure

• Temperature

• Duty cycle

A professional valve automation solutions provider should consider these parameters before recommending a suitable actuator.

Why Application Engineering Matters

Every industrial automation project has its own operating conditions.

A valve used in a water-treatment plant can have very different requirements from a valve installed in an oil and gas facility. Similarly, a simple on-off application can have very different actuator requirements from a modulating application.

This is why application engineering is important.
