- Compact Design: The compact and robust design saves space, allowing easy installation in tight working environments while providing full bore flow for unrestricted fluid movement and tool access.
- High-Pressure Rating: The standard working pressure is 5000 psi (350 bar), with optional configurations available for 3000 psi (210 bar) or 10,000 psi (700 bar) applications.
- Sealing Mechanism: The Kelly valve utilizes metal-to-metal sealing between the ball and seats, ensuring a reliable seal at both high and low pressures. The floating ball and seat design reduces the required torque for valve operation.
- Threaded Connections: Available with threaded connections in accordance with API 5B standards or GOST 633, allowing easy integration into the tubing string.
- Corrosion-Resistant Materials: Internal components are made of corrosion-resistant stainless steel. Optional materials complying with NACE MR01-75 standards are also available.
- Easy Maintenance: The valve is designed for quick disassembly and repair in the field, ensuring minimal downtime during workover operations.
Sizes and Dimensions:
- Available sizes range from 2 3/8″ to 4 1/2″, with corresponding lengths and weights:
- RKH-2 3/8 NU: Length 230mm, Weight 12kg
- RKH-4 1/2 NU: Length 380mm, Weight 55kg
- Additional sizes available upon request.
Applications:
- Workover Operations: Designed for use in well workover operations, providing reliable sealing and protection against fluid backflow in emergencies.
- High-Pressure Environments: Ideal for high-pressure drilling and completion applications, ensuring safe and efficient operation.
