Abstract
A process for the manufacture of a solenoid operated valve of the double valve seat type ensures that the stroke distance of a ball valve between two valve seats is accurately provided. The ball valve is positioned on a portion of a first valve seat member, and a first jig is mounted on the ball valve. The jig is pressed until an end surface thereof and an abutting surface of the first valve seat member are contacted, thereby forming a first valve seat. The ball valve then is positioned on a portion of the second valve seat member, and a second jig is pressed toward the ball valve until an end surface of the second jig abuts an abutting surface of the second valve seat member, thereby forming a second valve seat. The abutting surfaces of the two valve seat members are abutted, and the two valve seat members are assembled.
