What component needs to be replaced after installing a new valve plate on a reciprocating compressor?

After installing a new valve plate on a reciprocating compressor, it is essential to replace the suction valves. The reason for this is that the valve plate and the suction valves have complementary functions in the compressor. When a valve plate is replaced, it is often due to wear or damage that can affect the operation of the compressor, potentially altering the dynamics of how the suction valves perform.

Suction valves can experience wear that might not be immediately visible but can lead to decreased efficiency or failure. Since the entire sealing and operational integrity of the compressor rely on both the valve plate and the suction valves working correctly, it is advisable to replace the suction valves alongside the valve plate to ensure optimal performance and prevent any potential issues arising from degraded components.

Discharge valves, while they also play an important role in compressor operation, do not need to be replaced as frequently unless they are observed to be worn or damaged during inspection. Thus, the focus on replacing the suction valves ensures that the compressor will operate efficiently after a new valve plate installation.

In summary, replacing suction valves after valve plate installation is a best practice to maintain the compressor's performance and reliability.
