Upper top drive valves
5,000 psi, 10,000 psi & 15,000 psi
Intended for using as part of the upper power drive system for prompt overlap and pressurization of the drilling instrument tube channel in drilling the oil and gas wells, and also in maintenance and emergency works. (Mechanized control).
Using between the kelly and swivel 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 catline or interfere with operations.
