ABSTRACT:
A homogenizer comprises a homogenizing valve mounted to a pump block. Sets of three suction valves and discharge valves are positioned in valve bores in opposite faces of the block. Each of the valve bores has a hemispherical termination. The hemispherical termination of a pump chamber is formed in an adjacent surface of the block and is in communication with the valve bores through oblique conduits. The pump cylinder is formed in a packing box mounted in the block by bolts extending through the block. Integral valve assemblies removable as units are positioned in the valve bores. A pressure sensor is coupled to a discharge manifold through an isolating piston.
