The working pressure of float valve is supposed to be 5000psi or 10000psi. Float valve sub has two types:
The 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.
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.
