Plunger type model F drill pipe float valves

Plunger type model F drill pipe float valves

Description: 
This Float Valve is normally installed in a standard bore-back of the bit sub, to provide fluid flow control at the bottom of the drill stem. It also prevents backflow of cuttings from plugging the drill bit jets while making connections.
Plunger-Type Float Valves: 
Model F-Plunger Type Standard
The Model F is a plunger-type float valve that provides a positive instantaneous shut off, providing constant fluid control while drilling. The Model F is a reliable and economical selection under standard drilling operations.
Flapper-Type Float Valves:
Model G-Flapper Type Standard
The Model G is a flapper-type float valve that, when opened, offers an unobstructed bore through the float valve. The uniquely designed flapper closes rapidly to prevent shavings from entering the drill string when circulation stops and also assists primary BOP equipment in maintaining internal pressure control. The valve will fully open when the first joint is raised from the hole, preventing pulling wet joints.
