One piece kelly valves

5,000 psi, 10,000 psi & 15,000 psi

Designed for automatic overlap and pressurization of the drilling instrument tube channel in drilling oil and gas wells, and also in maintenance and emergency works.

When this valve is removed from the string, the internal parts are accessible for easy field repair. The smooth outside diameter allows this valve to be run anywhere in the string.
