ABSTRACT:
A panel mounted control valve including a housing having a bore with a valve seat formed in the bore. An axially and rotatably movable actuating member which has a valve member thereon is mounted in the bore for movement therein. A nut member is threadably mounted on an end portion of the actuating member and moves axially to compress or decompress a spring which biases the valve member to closed position. A slot is formed in the housing and the walls of the slot are located adjacent opposed flat portions on the nut member to prevent the nut member from rotating but permitting it to move axially.
