Multiway valve with a removable exhaust wall

A multiway valve for controlling the flow of a pressure medium from a delivery port to one of an exhaust port and a supply port, said multiway valve comprising:

• a valve housing having an axial bore and a plurality of steps forming a plurality of inner chambers, wherein said plural inner chambers are respectively connected to at least one delivery port, at least one exhaust port and at least one supply port;
• a spool arrangement operatively arranged for switching a flow pressure medium between said at least one delivery port and one of said at least one exhaust port and said at least one supply port, wherein said spool arrangement comprises two valve spools having mutually facing inner ends, said two valve spools being arranged coaxially and in tandem in said axial bore, each of said two valve spools being independently slidable within said axial bore;
• at least one drive piston corresponding to each of said two valve spools, wherein said at least one drive piston is axially movable in response to a control pressure for axially shifting a corresponding one of said two valve spools,
• one of said plural inner chambers comprising a common exhaust chamber arranged proximate said inner ends of said two valve spools at a central area of said axial bore and comprising a connection for said at least one exhaust port;
• and
• a removable exhaust wall operatively arranged between said inner ends of said two valve spools for directing an exhaust stream from each of said two valve spools to said at least one exhaust port.
