Manual Fill Float Collars

Type 700-PVTS Davis Float Collars come equipped with a flat concrete surface and load distributor plate for landing and sealing cement plugs. They normally are offered with pin and box thread con-nections, but are also available with double-box connections. Both of these designs embody the positive-seal, PDC drillable Davis PVTS spring-operated plunger-type valve molded in place with high strength concrete. When a back-pressure valve is not desired or required in a float collar, Davis has available the Type 701 Baffle Collar (not shown). This collar allows fluid low in either direction and provides a strong concrete surface to land and seal cement plugs. It is often run in tandem with the Davis Type 501 DV-PVTS double-valve, down-jet float shoe.
