Scott 11 FLUID VALVE APPARATUS ABSTRACT OF THE DISCLOSURE A fluid valve apparatus has a spool mounted for movement within a spool cavity of a body, the body having inlet and outlet ports therein. The spool has a spool closure portion which is adapted for seating against the outlet port when positioned thereagainst. The spool closure portion is responsive to fluid pressure acting on the spool which cooperates with the spool so as to displace the closure portion against the outlet portion to improve sealing therewith. The apparatus is particularly adapted for manufacturing by plastic injection, which provides a low cost, lightweight, corrosion resistant, easily adaptable valve assembly particularly for use in controlling liquid flows in medium bore pipes as used in forest fire fighting.
