Versatile Bore Options
Available in Full Bore and Reduced Bore configurations to match the system's flow and pressure requirements. This versatility allows you to tailor the valve to your specific application needs, ensuring optimal performance.
Customizable Options
The valve is available in a range of sizes and materials, including A694F52, A694F60, A694F65, A182F6A, A182F316, A182F347, and Inconel 625, allowing for customization based on specific industrial needs and environmental conditions.
Proven Reliability in Industrial Applications
Ideal for a variety of industries, including Oil & Gas, Chemical & Petrochemical, Power Generation, Water Treatment, and other high-pressure and general industrial applications. It is built to meet the rigorous demands of these industries, providing a reliable solution for critical pipeline systems.
What is the Double Block and Bleed (DBB) feature and why is it important?
Double Block and Bleed (DBB) allows the valve to block flow from both upstream and downstream sides simultaneously while providing a bleed port to vent or drain the cavity between the two seats. This is critical for maintenance safety and isolation in high-pressure pipeline systems, ensuring zero unintended leakage during servicing.
Is this valve compliant with international fire-safe standards?
Yes. The valve is designed and tested to meet Fire-Safe standards including API 607 and ISO 10497. These certifications confirm that the valve maintains structural integrity and continues to provide reliable sealing performance even when exposed to fire or extreme heat conditions.
What actuation types are compatible with this valve?
This valve supports multiple actuation methods, including manual handwheel, worm gear, electric actuator, and pneumatic actuator. It also features ISO 5211 direct mounting pads, making it straightforward to automate and integrate into existing control systems with minimal modifications.
What materials are available for different industrial environments?
The valve is offered in a wide range of high-performance materials including A694F52, A694F60, A694F65, A182F6A (Martensitic stainless steel), A182F316 (Austenitic stainless steel), A182F347, and Inconel 625 for extreme corrosion resistance. This range covers applications from standard oil and gas to highly corrosive chemical environments.
What is the difference between Full Bore and Reduced Bore configurations?
A Full Bore valve has an opening equal to the inner diameter of the pipe, allowing unrestricted flow and easy pigging operations. A Reduced Bore valve has a smaller flow path, which can be advantageous where space is limited or where slightly lower flow rates are acceptable, often at a lower cost and weight.
Which industries are best suited for this valve?
This valve is engineered for demanding industrial environments including Oil & Gas exploration and production, Chemical & Petrochemical processing, Power Generation plants, Water Treatment facilities, and general high-pressure industrial pipeline systems. Its robust construction and certifications make it suitable wherever safety, reliability, and longevity are required.
