Abstract
The hydraulic selector valve has a cock with pipe unions and a rotary plug with one or more bores, working against a seat between a flow position and one shutting off two or more unions from each other, together with a non-return valve. This valve (13, 14), is accommodated in one or more of the bores (12) in the plug (7). The plug can be spherical, while the non-return valve has a ball working between a seat and a stop limiting its movement in the other direction, a spring being fitted between stop and ball to thrust the latter against the seat.
