A valve for a reciprocating machine is disclosed. The valve includes a seat provided with flow apertures therein. A valve closing member is adapted to co-act with the seat for selectively closing and opening the flow apertures. A cage is connected to the seat and forms a guide, in which the actuation stem of a valve closing member is slidingly engaged and guided.

Fully actuated valve for a reciprocating machine and reciprocating machine including said valve

It is disclosed a valve () for a reciprocating compressor, comprising a valve body () which comprises a seat () and a guard (), the seat () and the guard () developing substantially parallel to a valve plane (A). The valve () also comprises a hydraulic apparatus () with pistons () and a hydraulic circuit () provided with a first portion () which is made by additive manufacturing technology according to digital 3D design data.
