Davis 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.
