Electric Ball Valve Applications Advancing Kazakhstan’s Oil & Gas Industry

A Successful Field Application Case in Kazakhstan

Introduction: Electric Ball Valves in Modern Oil & Gas Operations

In today’s oil and gas industry, electric ball valves play a critical role in ensuring safe, efficient, and precise control of gas and liquid media. Especially in natural gas production and processing, valves must deliver fast response, reliable sealing, stable control signals, and seamless integration with existing PLC and DCS systems.

As oil and gas operators worldwide seek cost-effective yet high-performance alternatives to traditional European brands, Chinese industrial valve manufacturers are increasingly proving their technical maturity and field adaptability.

This article shares a real on-site application case from Kazakhstan, demonstrating how Fleyenda electric ball valves successfully replaced legacy European brands without requiring any changes to the customer’s control system.

Customer Background: EMG Oil & Gas in Kazakhstan

EMG Oil & Gas is a subsidiary of Kazakhstan’s largest state-owned oil and gas group, with a history spanning over 100 years. The company’s core business includes:

• Geological exploration

• Oil and gas field development

• Oil and gas production

• Oil and gas preparation and treatment

Located in the Atyrau region, one of Kazakhstan’s most important oil and gas hubs,the customer operates more than 20 oilfields and production facilities.

Historically, their projects relied heavily on well-known European valve brands such as AUMA, ROTORK, and KITS, including both automated and manual valves.

The Challenge: System Compatibility with Existing PLC & DCS

As part of their cost optimization and localization strategy, EMG Oil & Gas decided to introduce Chinese-brand electric ball valves into their oil and gas facilities.

However, a major technical concern emerged:

• All existing PLC and DCS systems were originally configured to work with AUMA and ROTORK actuators

• Any mismatch could require rewiring, logic modification, or even system downtime

• Field applications required both ON/OFF control and modulating (control) functions, depending on the production stage

System compatibility and operational flexibility became the key decision factors.

Fleyenda Solution: One Electric Ball Valve, Two Control Modes

Fleyenda provided electric ball valves designed for oil and gas applications, offering both:

• On-Off (Open/Close) control

• Modulating (Regulating) control

The key advantage was that both control modes are integrated into the same electric actuator, and the desired function can be activated through simple on-site parameter settings, without hardware changes.

To ensure absolute reliability, Fleyenda dispatched both a sales representative and a technical engineer directly to the oil production site in Kazakhstan.

On-Site Technical Support: Seamless Integration Without System Changes

During the field visit, the Fleyenda team worked closely with Embamunaigas’ technical engineers to:

• Connect the electric ball valves directly to the existing PLC and DCS systems

• Verify signal compatibility with AUMA and ROTORK configurations

• Guide on-site adjustment of control parameters for different operating phases

• Demonstrate switching between on-off and modulating control modes

Most importantly, all of this was achieved:

✅ Without changing any existing wiring
✅ Without modifying PLC or DCS logic
✅ Without interrupting ongoing production

The electric ball valves were successfully commissioned and ran smoothly under real oil and gas operating conditions.

Electric Ball Valves in Natural Gas Applications

In natural gas production and processing, electric ball valves are widely used for:

• Gas flow isolation and regulation

• Pipeline switching and safety shutdown

• Pressure and flow control in treatment units

• Automated remote operation in hazardous areas

Compared with manual valves, electric ball valves significantly improve:

• Operational safety

• Response speed

• Control accuracy

• Automation level

Fleyenda’s electric ball valves are engineered to provide tight sealing, stable torque output, and reliable electrical control, making them suitable for demanding natural gas environments.

Results and Customer Feedback

Thanks to the close cooperation between both teams, the project was completed successfully and received high praise from EMG Oil & Gas.

Following the initial electric ball valve deployment, the customer proceeded to place additional orders, including:

• More electric ball valves

• Manual valves for supporting systems

This cooperation marked an important step toward long-term replacement of European valve brands with reliable Chinese industrial valve solutions in Kazakhstan’s oil and gas sector.
