What must a valve capable of functioning safely under CNG conditions do?

A valve that can function safely under compressed natural gas (CNG) conditions must be able to withstand pressures that are significantly higher than normal operating conditions. CNG is stored and transported at very high pressures, typically ranging between 2,000 to 3,600 psi, depending on the application and regulations. For the valve to operate safely and effectively within a CNG system, it must have a pressure rating that exceeds the maximum expected operational pressure. This ensures that the valve will not fail or leak under standard operating conditions, which is critical for safety and reliability in CNG applications.

In addition to pressure rating, valves must also adhere to other factors such as material compatibility and design integrity, but the ability to withstand high pressures is a fundamental requirement for their safe operation in CNG systems.
