In any industrial facility – from manufacturing plants to oil & gas refineries – valves play a critical role in controlling fluids and ensuring safe operations. However, like all mechanical equipment, valves are subject to wear and tear. A failed valve can lead to unplanned downtime, safety hazards, or costly production losses. That’s why a proactive maintenance program is essential. This article provides a detailed overview of industrial valve maintenance best practices aimed at keeping your valves (whether electric, pneumatic, manual, etc.) in top condition. We cover routine inspections, lubrication techniques, troubleshooting tips, and the use of predictive maintenance to address issues before they escalate.

The global push for clean energy has put hydrogen in the spotlight as a promising fuel and energy storage medium. From fuel cell vehicles to power plants, hydrogen applications are expanding rapidly. However, handling hydrogen – especially at high pressures (often 350–700 bar in storage and fueling systems) – presents a unique set of challenges. One critical component in any hydrogen system is the valve. Valves must withstand extreme pressures, prevent leaks of the tiny hydrogen molecules, and operate safely in a highly flammable environment. In this article, we explore the specific challenges engineers face when designing valves for high-pressure hydrogen service and the innovative solutions that have emerged to address these issues.

In 2003, Xi’an Jinzhu Modern Chemical Industry Co., Ltd. launched a new production line for HFC-134a refrigerant in Shaanxi Province, China. This facility – with an initial capacity of 5,000 tons per year – was part of China’s push to produce ozone-friendly refrigerants after the phase-out of CFCs. HFC-134a (1,1,1,2-tetrafluoroethane) is a widely used refrigerant gas, but manufacturing it is a chemically aggressive process. The production involves highly corrosive chemicals, including anhydrous hydrogen fluoride (HF) and other halogenated intermediates. From the outset, the Xi’an Jinzhu plant faced a critical engineering challenge: how to handle extremely corrosive process fluids reliably and safely. Valve failure in this process could lead to HF leaks – a grave safety hazard – or to costly downtime in a continuous chemical process.

Chemical processing plants deal with some of the most corrosive fluids in industry – acids, caustics, solvents, brine, and abrasive slurries can all wreak havoc on standard valves. Choosing the wrong valve material can lead to leaks, premature failure, or even dangerous accidents if a critical valve ruptures under corrosive attack. For B2B procurement managers and industrial engineers, selecting corrosion-resistant valves is both a safety imperative and a financial one (since unexpected downtime or environmental releases can be extremely costly). This article provides a guide to selecting the right valve materials and designs for the chemical industry, comparing options and highlighting key engineering considerations.
