A Flow Line Check Valve is an essential component in high-pressure piping systems that prevents backflow and ensures smooth directional flow of fluids. It is used in various industrial applications, including oil and gas extraction, high-pressure processing, and wellbore operations.
This valve comes in two main types:
Flapper Check Valves: Designed to allow flow towards the wellbore and block reverse movement using a flapper mechanism. These are available as top-entry or in-line configurations.
Dart Check Valves: Equipped with a dart mechanism controlled by a spring, where forward fluid pressure opens the dart, and reverse pressure forces it against the seat, preventing backflow.
Built to withstand extreme pressure conditions, the Flow Line Check Valve is manufactured from forged high-strength alloy steel with a nitrile-butadiene rubber-coated internal baffle for enhanced durability. Its American standard thread and union connection facilitate easy installation and secure operation.
These check valves are particularly beneficial for isolating completion fluids, handling high-pressure processing, and conducting rig equipment repairs. They can also be customized for sour service conditions in compliance with NACE MR0175 standards, ensuring compatibility with challenging environments.
The Flow Line Check Valve is designed for durability and high performance in extreme working conditions. Below is a detailed table outlining its technical specifications:
Prevents Backflow: Ensures directional fluid movement by stopping reverse flow automatically.
High Pressure Tolerance: Designed for pressures up to 15,000 psi, making it suitable for extreme industrial applications.
Multiple Connection Types: Available with Union, BOX thread, and Pin thread connections for easy installation.
Corrosion-Resistant Design: Manufactured from forged alloy steel for superior durability.
Enhanced Sealing Performance: Nitrile-butadiene rubber-coated internal baffle extends the valve's service life.
Compliance with Standards: Meets API 6A and NACE MR0175 requirements for safe operation in sour environments.
Flapper & Dart Variants: Provides flexibility for different operational needs.
