Zhejiang BIGTORK Valve Automation Co., Ltd. has successfully completed the ADNOC supplier pre-qualification process for two key product categories: Pneumatic Actuators and Hydraulic Actuators.

This milestone marks an important step in BIGTORK's expansion into the Abu Dhabi oil and gas market and strengthens our ability to support oil & gas operators, EPC contractors, valve manufacturers, distributors, and industrial customers across the Middle East.

As shown in our ADNOC supplier profile, BIGTORK is currently listed as "Pre-qualified" for：

The pre-qualification was established through a formal supplier and agency structure, with BIGTORK represented by an authorized UAE-based agent in the ADNOC supplier system.

ADNOC

A New Step into the ADNOC Oil & Gas Supply Chain

The Abu Dhabi National Oil Company (ADNOC) is one of the major energy companies in the Middle East, with operations covering upstream, downstream, trading, and other areas of the energy value chain.

For industrial suppliers, ADNOC operates a structured supplier registration and pre-qualification process. According to ADNOC's official Supplier Hub, companies seeking to do business with ADNOC Group first register as suppliers and then proceed to pre-qualification for eligible product or service groups.

ADNOC's pre-qualification process evaluates information such as relevant supply experience, applicable international standards, quality and HSE documentation, and available technical and operational resources.

For BIGTORK, completing this stage represents more than simply adding another supplier credential.

It is an important step toward establishing a long-term presence in the Abu Dhabi and Middle Eastern oil & gas valve automation market.

What Does ADNOC "Pre-Qualified" Mean?

For customers who are not familiar with ADNOC's procurement process, it is important to distinguish between supplier registration, pre-qualification, and final approved-vendor status.

ADNOC's supplier process includes registration followed by product/service-specific pre-qualification. Once the relevant registration requirements are fulfilled, suppliers can proceed to pre-qualification for eligible product or service groups.

In BIGTORK's current case, our supplier profile shows:

Supplier Status: Pre-qualified

Product Groups:

This means BIGTORK has successfully passed the current pre-qualification stage for these product categories.

It does not mean that BIGTORK is already claiming final ADNOC AVL approval for every project or application.

We consider this distinction important because transparency is essential when working with international oil & gas procurement teams.

Our next objective is to continue completing the applicable qualification, technical, inspection, testing, and project requirements necessary for future ADNOC-related opportunities.

Why BIGTORK Was Ready for ADNOC Pre-Qualification

The successful pre-qualification is supported by BIGTORK's existing manufacturing experience, quality management system, valve automation expertise, and international project capabilities.

ISO 9001 Quality Management System

BIGTORK maintains an ISO 9001 quality management system, supporting standardized manufacturing, inspection, quality control, and documentation processes.

The ADNOC supplier profile provided for this announcement also contains the relevant ISO 9001 certification documentation, with the certification information shown in the supplier system.

For oil & gas customers, a documented quality management system is particularly important because actuator performance must remain consistent across engineering, machining, assembly, testing, inspection, and final delivery.

Authorized UAE Agency Structure

BIGTORK's ADNOC supplier profile shows a formal Manufacturer / Associate relationship with an authorized UAE-based agent.

The supplier system records the agency relationship as:

Agency Type: Representation

and shows an agency expiry date of 16 July 2028.

This provides BIGTORK with a structured local representation model for supporting business development and supplier-related activities in the UAE.

The combination of a Chinese manufacturing base and local UAE representation allows BIGTORK to better support customers requiring communication between factory engineering teams, regional representatives, valve companies, EPC contractors, and project procurement teams.

Pneumatic and Hydraulic Actuators for Oil & Gas Applications

BIGTORK specializes in valve automation solutions covering pneumatic and hydraulic actuation technologies.

Our existing product portfolio includes pneumatic actuators, hydraulic actuators, linear actuators, Scotch yoke actuators, rack and pinion actuators, and customized actuator solutions.

For oil & gas applications, actuator selection is not simply about output torque.

Engineering teams may need to consider:

Valve type and size
Required torque or thrust
Operating pressure
Fail-safe requirements
Operating temperature
Corrosive environments
Emergency shutdown requirements
Open/close operating time
Manual override requirements
Fire protection requirements
Partial stroke testing
Control accessories
Installation environment

Applicable international standards

BIGTORK's experience in valve automation enables us to work with customers on actuator sizing, configuration, control accessories, and customized solutions for demanding industrial applications.

Our website currently presents dedicated product categories for both Pneumatic Actuators and Hydraulic Actuators, allowing procurement and engineering teams to identify the appropriate technology for different valve automation requirements.

Built for Demanding Oil & Gas Environments

Oil & gas facilities in the Middle East can present challenging operating conditions, including:

High ambient temperatures
Coastal and salt-laden environments
Dust and sand exposure
Corrosive atmospheres
Outdoor installation
Hazardous-area requirements
Emergency shutdown applications
Continuous or frequent valve operation

For these applications, actuator reliability depends on more than the actuator's nominal torque.

Material selection, sealing systems, surface protection, mechanical design, machining accuracy, testing, and control configuration all contribute to long-term performance.

BIGTORK continues to develop actuator solutions for demanding valve automation applications, including ESD, BDV, fire protection, partial stroke testing, quick shutdown, and other specialized control requirements.

Our approach is to evaluate the actual operating conditions of each project before recommending the actuator configuration.
