Common Causes of Control Valve Stem Leakage and How to Prevent Them

Control valves are the workhorses of process control They regulate the flow of fluid to maintain the performance efficiency. Stem seal leakage is one such area of concern which can be very common in control valves. This will be inefficient, high maintenance and maybe even unsafe. 

What are the most common causes of control valve stem leaks

Valve Stems Packing Control Valve Steam Leakage One of the most common causes of control valve steam leakage is degradation of the valve stem packing. With wear and use, the packing material can break down under severe operating conditions with leak as a result. This can be prevented, however, by periodic checking of the valve packing and replacing it when necessary. 

Valve stem leak prevention and how to maximize performance

Outside of prevention and repair works there are several things you can do to help prevent the leaking. First and foremost, keep in mind the actual operating conditions of the valve. Oil rig on land is subjected to various external environments, and factors including elevated temperature, high pressure, corrosive fluids and abrasive media can accelerate valve packing wear. 

Knowing how control valve stem leaks develop and what to do about them

In addition to typical causes of control valve stem leaks, the following factors should be considered in a complete analysis. Besides wear and tear and incorrect installation, factors such as over travel of the stem, frequent cycling, poor lubrication may also cause the leak of the stem. 

Reducing control valve stem leakage for increased productivity and cost savings

Focusing on avoiding work over rig is particularly important when you consider that it can impact cost savings. Leakages at control valves can lead to losses in power, process efficiency and pose environmental risks. 

Field-proven solutions for reducing the risk of control valve stem leaks 

stem leaks of control valve is a very common problem that can effect the efficiency and safely of industrial facilities'. By learning the source of stem leaks, and how to prevent them, you can lower down time, improve productivity and save money.
