Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

The 362 Series is a three-way valve made for single-acting process valve applications, while the 562 Series is a four-way spool valve designed for double-acting process valves. The valves' high flow ...
