Product Description

Product Description

Float valve sub

Description:
Float valve Sub is an important tool in petroleum exploration and drilling engineering. The float valve sub is connected at upper part of drill bit. The float valve sub is near the bit connecting thread. The float valve sub can also be used at different necessary position of drill string when required. The main application is, when connected with single piece pipe, it prevents mud from coming in and up blocking the hole. When blowout takes place, blowout in drill string will be avoided because nozzle is closed automatically by valve cap of the float valve assembly. The working pressure of float valve is supposed to be 5000psi or 10000psi. Float valve sub has two types:

Model F is a plunger-type float valve that provides a positive instantaneous shut off, providing constant fluid control while drilling. This plunger-type float valve is a reliable and economical selection under standard drilling operations.

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.
