<p>An improved valve construction comprising a molded valve body including a plurality of body sections (2a, 2b) each having a generally flat inner surface (3), and the inner surfaces (3) are disposed in contiguous relation along an interface. Each inner surface (3) is formed with a plurality of recesses (513, 24) that mate with and complement recesses (5-13, 24) in the inner surface of the other body section (3) to form a valve chamber (6) and a connecting fluid piston chamber (24) for receiving an actuator piston (23). A spool valve (20) disposed within the valve chamber (6) for sliding movement therein to control fluid flow to an external operating member (not shown), upon sliding movement of the piston (23) by pressurized fluid within piston chamber (24).</p> |
