How to Troubleshoot and Maintain Pressure Regulators

By Jonathan (Jon) Kestner |

Following a five-step process enables better outcomes for fluid system control Most often, operators and technicians will interact with components like ball valves or needle valves when adjusting a system’s operation. However, just as important to the effectiveness of a system are the pressure regulators that work to deliver steady pressure, so these common valves can perform their function. Pressure regulators are complex fluid system components that require careful thought during system design, installation and operation to realize safe, trouble-free performance. A regulator’s main purpose is to maintain steady pressure in a fluid system application. However, a regulator’s ability to reliably perform that function can become compromised over time and may require investigation to determine if the regulator itself is the problem or if another system issue is to blame. Issues such as the following are most commonly related to the regulator’s seat, diaphragm and poppet: Pressure leakage across the seat when closed Loss of pressure control Fluid leakage to atmosphere These issues do not necessarily mean the regulator needs to be replaced. The regulator can likely instead be maintained to prolong its life and reduce its…
