Oil and Gas

In the demanding environment of oil and gas processing, reliability and safety are non-negotiable. At Mark & Aira Valves, we expand our specialized inventory to include advanced flow control technologies designed for upstream, midstream, and downstream applications.

1. Trunnion Mounted Ball Valves

For high-pressure and large-diameter pipelines, our Trunnion Mounted Ball Valves offer superior stability. Unlike floating designs, the trunnion-style ball is supported by bearings, reducing operating torque and ensuring a tight seal even under extreme pipeline pressure. These are essential for gas transmission and heavy oil processing.

2. Double Block and Bleed (DBB) Ball Valves

Safety and integrity are paramount during maintenance. Our DBB Ball Valves provide a dual-barrier system in a single unit. By allowing the operator to bleed off trapped pressure between the two seating surfaces, these valves ensure a verifiable bubble-tight seal, making them the industry standard for critical isolation services.

3. Triple Offset Butterfly Valves

When zero-leakage is required in high-temperature or high-pressure steam and gas applications, our Triple Offset Butterfly Valves are the ideal solution. The unique geometry prevents friction between the seat and seal ring, significantly extending the valve’s life and reducing maintenance costs in refinery operations.

4. Through Conduit Gate Valves

Specifically engineered for the “piggable” pipelines common in the oil and gas sector, our Conduit Gate Valves feature a full-bore design. This minimizes pressure drop and turbulence while allowing for the easy passage of pipeline scrapers (pigs) and ensuring a smooth flow of crude oil and natural gas.

5. Swing Check Valves

To prevent backflow and protect expensive pumping equipment, we supply heavy-duty Swing Check Valves. Designed with a full-flow area and robust hinge pins, these valves respond automatically to flow changes, providing reliable non-return service in both horizontal and vertical pipeline orientations.

Advanced Automation and Actuation

Modern oil and gas facilities require precision control and remote operation capabilities. We provide cutting-edge actuation solutions to automate your flow control.

6. 3-Phase Electrical Actuators

Our 3-Phase Electrical Actuators are built for heavy-duty industrial environments. They offer high torque output and precise positioning for large-scale valves. These units are available in explosion-proof housings, meeting the strict safety certifications required for hazardous oil and gas zones.

7. Motorised Valves

Enhance your operational efficiency with our range of Motorised Valves. By integrating high-quality gate, ball, or butterfly valves with electric motors, we provide turnkey solutions for automated flow management, allowing for seamless integration into your facility’s SCADA or control system.
