The Api Kelly Valve, also known as a Kelly Cock or Drill Pipe Safety Valve, is engineered to allow the free passage of drilling fluid without pressure loss during oil and gas operations. This valve can function as an upper Kelly valve to control blowout pressures or as a lower Kelly valve to prevent drilling fluid loss when the Kelly is disconnected. It is available with pressure ratings of 5,000psi, 10,000psi, or 15,000psi, making it suitable for high-pressure drilling environments where safety and fluid control are critical.
Constructed for durability, the valve is typically made from high-grade alloy steel to withstand corrosive drilling fluids and extreme pressures. Standard industry designs include full-bore openings to minimise pressure drop, with typical temperature ratings ranging from -20°C to 120°C depending on the application. The valve’s compact design ensures compatibility with most drilling rig setups, and its manual operation allows for quick engagement in emergency scenarios.
This product is primarily used in onshore and offshore drilling rigs for oil, gas, and geothermal exploration. Buyers include drilling contractors, oilfield service companies, and energy exploration firms that require reliable pressure control solutions. The valve is typically supplied as a standalone component, with trade terms such as FOB or CIF negotiated per order. Confirm packaging, lead time, and compliance with API 7-1 or 7K standards with the supplier before finalising an order.

Before ordering, verify the valve’s pressure rating and compatibility with your drilling rig’s Kelly system. Request the supplier’s test certificates for pressure and temperature ratings, and confirm whether the valve meets API 7-1 or 7K standards. Insist on documentation for material composition and manufacturing processes to ensure compliance with safety regulations.
Discuss logistics details such as lead time, which may vary based on order volume and customisation. Clarify Incoterms (e.g., FOB or CIF) to determine responsibility for shipping costs and risk transfer points. Payment terms, such as TT or LC, should also be agreed upon in advance to avoid delays. Request packaging specifications to ensure the valve arrives without damage, as improper handling can compromise its integrity.
Conduct a pre-shipment inspection to verify dimensions, material quality, and pressure-test results. Ask for a third-party inspection report if required by your procurement standards. Ensure the supplier provides a certificate of conformity and a mill test report for the alloy steel used. For offshore applications, additional non-destructive testing (NDT) may be necessary to confirm structural integrity under marine conditions.
