Easy control valve solutions: process control optimization through fail-safe vane actuators
Posted by John Butterfield | 06 February 2018
Optimal process control depends on multiple components working properly. However, positioners, actuators, and valves are the only pieces of equipment that move, which means they’re often the weak link of the loop. This movement causes problems such as hysteresis, stiction, and increased response time, reducing the overall control loop performance. Proper actuator selection is necessary to address these problems, because actuators are at the center of every moving part of the control valve.

Through conduit double expanding gate valves
Posted by David Sear | 07 November 2017
Through conduit gate valves are manufactured as per standard API 6D. These valves are preferred for dirty (suspended/abrasive) or fouling service because of the fact that, unlike normal gate valves, their wedge/gate (closure member) is not open to flow stream and so free from jamming or obstruction. These valves are suitable for onshore and offshore application and can be used for isolation purposes.

Posted by Roy van IJzendoorn | 26 September 2017
Multiport Selector Valves (MSVs) can play a key role to optimise engineering and management of production facilities, as well as testing of oil and gas wells. Conventional production manifolds are typically expensive, complex and difficult to maintain. Employing an MSV in place of many actuated valves can lead to several advantages, such as fewer automation systems; smaller, lighter and more reliable skids; overall lower cost for installation, commissioning, operation, maintenance and ownership.
Mitigating MOV stem nut failure through proper maintenance and wear measurement
Posted by Roy van IJzendoorn | 19 September 2017
A major problem with stem nut thread failure is that stem position is usually interpolated from the number of stem nut rotations. If the stem nut threads strip out, the stem nut will still turn but will give a false indication of position to the control room. Such a failure of control and indication on a valve could cause a critical safety or environmental incident. This paper reviews approaches to stem nut maintenance and introduces a more scientific approach to measure stem nut thread wear.
