Valves used in process safety applications remain static for much of their existence in a manufacturing or production process. Digital valve controllers can play an essential role in ensuring these valves operate as they should when called upon in an abnormal situation. For safety valves used in throttling applications, digital valve controllers enable precise control through accurate valve positioning to avoid process instability, which can lead to unplanned shutdowns.

by | Mar 17, 2025 | Safety, Valves, Actuators & Regulators | Update and bump: A LinkedIn post on this subject went viral, so I thought it would be worth sharing Riyaz Ali‘s thoughts on this subject again. Abstract Final Control Elements (Control valves or Safety Shut Down Valves) are the key components of any close loop control system, whether it is used for Basic Process Control Systems (BPCS) or for Safety Instrumented Systems (SIS).

Generally, depending upon the design of internal components of smart devices and their response to control change from the controller input signal, pneumatic parts like I/P (current-to-pressure transducer) and pneumatic relays are tailored to optimize control performance. There are a few types of pneumatic relay designs, each with features as listed below. Mechanical Balance Beam Design.

I’ve often written about how digital valve controllers improve control valve performance and ongoing maintenance. But how about on-off valves? In this Valve World Americas featured story, How Digitized On-Off Valves Improve Operations, Emerson’s Riyaz Ali explains how the:…data provided by smart on-off valves can be used to increase uptime, reduce maintenance costs, and improve safety. Riyaz opens the article by highlighting some examples where on-off valves can be found.
