BUENO diaphragm valve quality comes from its half centuries of PTFE diaphragm technology

Diaphragm valves consists of a valve body with two or more ports, an elastomeric diaphragm, and a "weir or saddle" or seat upon which the diaphragm closes the valve. The valve body may be constructed from plastic, metal, wood or other materials depending on the intended use.
BUENO has experience over 50 years of development and manufacturing of diaphragm valve and all of its parts.
