ABSTRACT:
The float operated control valve includes a one-piece molded plastic valve body having a valve chamber, a first cylindrical extension defining an inlet chamber in communication with the valve chamber, a second cylindrical projection defining an outlet chamber in communication with the valve chamber and disposed at right angles to the first cylindrical projection and a third cylindrical projection having a cylindrical passage in which a plunger is slidably mounted. The plunger has a valve member mounted on one end thereof within the valve chamber for engagement with a valve seat surrounding a passage between the inlet chamber and the valve chamber. A diverter plate is disposed at an angle to the axis of the first and second cylindrical projections for diverting the fluid entering the valve chamber from the inlet chamber toward the outlet chamber. An apertured plate is detachably mounted in the inlet chamber for providing turbulence to reduce the pressure and to prevent the passage of large particles which would damage the valve member.
