Can the tapered plugs in tapered plug gas valves be interchanged?

In the context of tapered plug gas valves, the correct understanding is that the plugs are specifically machined and mated to their respective bodies. This precision in manufacturing is crucial because the tapered design creates a specific sealing surface that ensures a tight and reliable closure when the valve is in the closed position. Each plug is made to fit its matching valve body to ensure optimal performance, prevent gas leaks, and maintain safety standards.

If the plugs were interchanged with those from other valves or even other plugs of the same type, it could lead to improper sealing. This increases the risk of gas leaks, which could pose significant safety hazards. Therefore, the integrity of the valve's operation hinges on the compatibility of the tapered plug with its designed body, underscoring the importance of not interchanging these components.
