A slide valve and coupler assembly for controlling flow in one line when attached only to that line and for controlling flow in a fluid line correction between two lines when coupled between those two lines, comprising, in combination, (a) a slide valve comprising: (1) a valve housing having a fluid inlet and a fluid outlet and means for attaching a first line to one of the inlet and outlet; (2) a first fluid flow passage through the housing between the fluid inlet and the fluid outlet; (3) at least one slide valve member; (4) guide means in the housing for guiding the slide valve member into a position across and closing off the passage to fluid flow and away from that position, leaving the passage open so that fluid flow can proceed past the valve; (5) the slide valve member being carried on and reciprocable into and away from said closed position along said guide means; and (b) a coupler comprising: (1) a coupler housing having a fluid inlet and a fluid outlet and means for attaching a second line to one of the inlet and outlet; (2) a second fluid flow passage through the coupler housing between the fluid inlet and the fluid outlet; (3) a first recess for receiving at least the slide valve member-containing portion of the slide valve housing; the first flow passage through the valve housing and the second flow passage through the coupler housing being in alignment when the valve housing is in the first recess; (4) at least one second recess abutting and beside the first recess, receiving the slide valve member in a position away from the flow passage through the slide valve housing; (5) operating means for sliding the slide valve member, when the valve housing is inserted in the first recess, between said positions across and closing off the flow passage through the assembly, and away from and opening the flow passage through the assembly; and (6) retaining means on said operating means connecting with the valve housing when the operating means is operated to slide the slide valve member to said opened position; and retaining the slide valve to the coupler; whereby the slide valve member controls flow in the first line when the slide valve housing is attached only to that line, and controls flow in the first and the second lines when the slide valve housing is inserted in the first recess of the coupler, and the assembly is attached to the first and second lines.
