Zusammenfassung:	Apparatuses and methods overcoming the technical challenges in actuating valves of reciprocating compressors used in oil and gas industry are provided. A valve assembly includes an actuator, a shaft, a collar and a thrust bushing. The actuator is configured to generate a displacement. The shaft configured to receive a rotating motion caused by the displacement and to penetrate inside a compressor body of the reciprocating compressor. The collar is located close to a location where the shaft penetrates inside the compressor body. The thrust bushing is located between the collar and the compressor body. The rotating motion actuates a valve closing member of a valve inside the compressor body.
