Top Entry Ball Control Valve Features
The Top Entry Ball Control Valve is an innovative solution tailored for the oil and gas industry, focusing on reduced operational effort and simplified maintenance. Here are the detailed features that highlight its design and functionality:
1. Dual O-Ring Seals: This design ensures a tight seal around the stem area, preventing any potential leakage and maintaining the integrity of the valve.
2. Blow-out Proof Stem: A critical safety feature that guarantees the stem remains sealed under all pressure conditions, providing reliable operation and preventing accidental release.
3. Backup Metal-to-Metal Sealing: In the unlikely event that the primary soft-seat materials are compromised, such as in a fire scenario, the metal-to-metal sealing acts as a secondary barrier to ensure shutoff capability.
4. Integral One-piece Body: The valve's body is constructed as a single piece, offering the same structural rigidity as the pipeline itself, which ensures consistent performance and durability.
5. O-Ring and Gasket Seal Combination: This combination provides an additional layer of protection against leakage at the body connection area, further enhancing the valve's sealing performance.
6. Floating Spring-loaded Seats: These seats are designed to maintain a seal even at low pressures, ensuring the valve's effectiveness across a wide range of operating conditions.
7. Emergency Sealant Injection Fitting: This feature allows for external intervention in the event of a seat leak. By injecting a sealant, operators can quickly address the issue and restore the valve's sealing capabilities.
