Kelly Cock Valve Upper And Lower - China

price: contact company for price

The MDX Ball Type Kelly Valve provides a quick, sure shutoff

in the drill string that can repay the cost of the valve

quickly in the mud savings and kick protection.This valve

can be used as either an upper or lower kelly cock. It has

an exclusive corrugated spring to insure a positive seal.

Standard pressure rating is 10, 000 pound test, but higher

pressure ratings are available on special order. The ball is

stainless steel, and closes easily. The MDX Kelly valve is

full-opening, so it does not interfere with the running of

tools such as core barrels or survey instruments. Its

streamlined O.D. is the same as the tool joint O.D.

Upper Kelly Valve:The MDX Kelly Valve is also available with

left-hand threads for use as an upper kelly cock. When used

between the kelly and swivel, it provides a positive means

for shutting off flow in the drill string at any time. The

inline body design will not hang up on the cat line or

interfere with operations.

Lower Kelly Valve:When used as a lower kelly cock, the MDX

Kelly Valve provides a closure to stop mud loss when the

kelly is disconnected from the drilling string. Just close

the valve before disconnecting and mud in the kelly and

hoses stays there. With the cost of oil mud, biopolymers and

other costly drilling fluids, the valve can pay for itself

quickly. The rig floor and substructure stays much cleaner

and safer as well. Its streamlined O.D. allows it to pass

through the blowout preventer smoothly.
