Valves
Velan releases upgrades to its delayed coker isolation valves
A newly added lower tangential purge directs steam precisely to areas where coke accumulates in stagnant cavities, creating a loop‑flow around the ball for improved cleaning efficiency with a non‑plugging purge design.
An introduction to valves standards
Valves are essential components across industries such as oil and gas, power generation, water treatment and chemical processing. They regulate and/or isolate fluid flow, ensuring safe and efficient system operation. To guarantee reliability and performance, valves must conform to rigorous standards developed by organizations like the American Petroleum Institute (API), the American Society of Mechanical Engineers (ASME), the Manufacturers Standardization Society (MSS) and the International Organization for Standardization (ISO).
Digital Exclusive—Valve maintenance: An open and shut case?
Maintaining valves throughout a plant’s lifetime helps to preserve optimal performance, minimize supply disruptions and reduce environmental impacts; however, it can be challenging. Remote locations, extreme operating conditions and the often-aggressive properties of the fluids being transported can pose specific servicing and maintenance challenges.
