Fabri-Valve C45 DFV

The C45 DFV (Drilling Fluid Valve) met the demand for heavy duty replaceable seats – and with that we changed everything. Production expectations were raised. Drilling fluid systems functioned more efficiently and effectively.

The basic Fabri-Valve C45 features a solid ductile iron or carbon steel body with an integral cast metal seat. However, this valve is most often used with the patented, pop-in style replaceable seats, which are available in a variety of rubbers, polyurethane, UHMW-P, TFE, and hard-faced metal. The pop-in seats feature a much larger cross section and seating area than conventional knife gate valve seats thus providing a seating surface far removed from the flow stream. Replaceable seats offer a unique advantage, abrasion resistance, long seat life, and the convenience of easy seat replacement.
