  • Kelly Cock: API Compliant Kelly Valve for Well Control

Short Description:

Our Kelly cocks (Kelly valves) are critical well control components, including kelly valves, poppet check valves, and dart check valves. The kelly valve consists of an upper and lower cock: the upper connects to the top of the kelly (left-hand thread), and the lower connects to the bottom (right-hand thread). Both are ball-type valves with identical construction.
High-pressure fluid components are designed and manufactured to strict standards including API 6A, API 16C, API 5L, ANSI/ASME, and NACE MR0175. These products offer exceptional performance, interchangeability, high pressure resistance, reliable sealing, long service life, and stable quality. All outlet connection dimensions are in inches, ensuring compatibility with international products.
