Abstract
A sludge pump valve for use in pumping systems which pump aggressive, abrasive, and corrosive liquids containing granular material, pumped over long distances and at high pressures, employs a pair of elastic sealing elements provided, respectively, with spherically configured convex and concave surfaces that mate along a spherical contact surface during valve closing to effect leak-free seal of the valve, the arrangement being such that valve is made more maintenance free and has a longer service life.
