Abstract: A slow start valve has a first valve member for opening and blocking a flow passage between an inlet port and an outlet port and a second valve member for opening and blocking a flow passage between the outlet port and an exhaust port, both being integrally formed in a spool without adopting a poppet construction, wherein the actuation of the spool by force of compressed air causes slow supply, quick supply and exhaust. Compressed air supplied via a solenoid three-way valve causes a piston to move downward along with the spool in contact therewith and then compressed air supplied via a passage causes the spool to move further downward, a second valve opening being immediately shut off with the second valve member.

Abstract: In a miniature solenoid valve having a valve casing with a valve chest and a plurality of flow passages in communication with said valve chest formed therein; a valve body movably received in said valve chest for controlling the communication between the valve chest and said passages; and a solenoid provided adjacent to said casing for moving said valve body by means of a plunger, the casing is formed with an opening in communication with the valve chest, the solenoid is removably received at one end of the solenoid in the opening and the valve casing and the solenoid are secured together by means of fixing means including fixing pins passing through the casing and solenoid.
