Valve having junction type housing

A valve having a junction type housing, the housing comprising a valve hole through which a valve rod moves, a plurality of ports which are in communication with the valve hole, and a substantially flat mounting surface to be mounted on a sub-plate, wherein

• the housing comprises an upper first housing member and a lower second housing member which are divided by a dividing surface including a center axis of the valve hole, a plurality of connecting holes extending perpendicular to opposed joint surfaces of the housing members and a plurality of connecting pins which are fitted into opposed connecting holes are formed in the opposed joint surfaces of the housing members such that the connecting holes and the connecting pins are opposed to each other, the connecting holes and the connecting pins functions as positioning mechanisms and connecting mechanisms, solder is applied to inner surfaces of the connecting holes and/or outer surfaces of the connecting pins to fix the connecting pins and the connecting holes to each other, thereby integrally connecting the first housing member and the second housing member with each other in a state in which they are positioned.
