Abstract

PURPOSE:To prevent a flow duct from submerging and adhering of a particulate, by providing a valve body, an inlet and an outlet of a fluid and a hydraulic pressure actuation type valve, and by applying a coat of tetrafluorothylene to a base body and a flow duct which touches the fluid of a directional control valve. CONSTITUTION:A pilot signal is applied into a gateway 8 and then applied to the lower part f a piston 12 in a piston chamber 6, which pushes the piston 12 upward against compression force of a spring component 16. As a valve stem 14, therefore, secured with a piston 12 in a body is moved upward as well and a protrusion 13a of a valve plug 13 at the lower part of the valve stem 14 is separated from a valve seat 32, paint or a solvent entered into a fluid duct 4 through a fluid gateway 5a from a hydraulic coupling instaled on a flluid inlet 5 is passed through a fluid outlet 4a first, then reached to a fluid exhaust duct 37 through a gateway 41 and a central opening 40 of a base body B and led to a spray gun.
