PNEUMATIC OPERATION VALVE

摘要

PURPOSE:To reduce the size of a pneumatic operation valve and enable the connecting direction of an air supply pipe of being determined arbitrarily by forming a control air supply inlet in the axial side face of a casing which can be turned with respect to a main body. CONSTITUTION:A pneumatic operation valve has a control air supply port 7 formed on the axial side face of a casing 5 which contains a piston 1 as it can be slided therein. the casing 5 can be turned with respect to main body 5. The air supply pipe can thereby be connected to the side of the casing and reduced in vertical length thereof, and pipes can be arbitrarily connected to each other on the plane of 360 deg. turning direction of the casing. The designing of the object equipment controlled by such valve will not be restricted by piping of the air supply pipe.
