A compact valve and actuator includes a housing with a cylindrical bore which is open on one end of the housing and substantially closed at the second end except for an inwardly extending coaxial inlet tube. A cylindrical slide member is concentrically received between the outside of the tube and the inside of the bore and is provided with a piston-forming flange which is restricted in axial movement by a stop ring also located around the slide member midway of the bore. The second end of the bore and the stop ring form ends of a cylinder for the aforementioned piston-forming flange of the slide member. The slide member further includes valving apertures which cooperate with the stop ring to communicate fluid received via the inlet tube either to the open end of the bore, or via apertures in the stop ring to a by-pass.

A valve suitable for mounting in an aircraft for controlling fluids for agricultural spraying, said valve comprising: a housing provided with a bore defining a cavity having a substantially closed end except for a tubular member extending coaxially into said cavity from said end for providing a fluid flow passage, and a slide member having a first end received coaxially between said bore and said tubular member forming an actuating means toward said substantially closed end of said cavity, said slide member being closed on its second end and having side openings to form valving means with said tubular member for providing selective communication of fluid between said tubular member and said bore in accordance with the axial position of said slide member.
