What should valves, valve packing, and gaskets be designed to withstand?

Valves, valve packing, and gaskets in a compressed natural gas (CNG) delivery system are critical components that must function reliably across various operating conditions. They need to be engineered to handle the full range of pressures and temperatures that can occur during operation. This ensures that they can effectively seal the system and prevent leaks, which is crucial for safety and efficiency.

Designing these components to withstand only ambient environmental conditions, extreme vacuum conditions, or solely maximum temperature conditions would impair their performance and the safety of the entire system. Ambient conditions do not account for the varying and often extreme pressures and temperatures that can occur while the CNG is being transported and utilized. Therefore, ensuring that valves, packing, and gaskets are built to manage the complete spectrum of operational pressures and temperatures is essential for maintaining system integrity and preventing failures.
