Side Entry Trunnion Ball Valves: Designed for Severe Service and High-Pressure Isolation
Unmatched Reliability for Hydrocarbon Service
We specialize in supplying Side Entry Trunnion Ball Valves designed to conform strictly to the API 6D pipeline valve standard. These valves are engineered as robust, severe-service components capable of withstanding the demanding requirements of the onshore and offshore Oil and Gas, Oil Refining and Processing, and Petrochemical industries.
Our side entry design provides consistent, reliable, and swift zero-leakage shut-off, making these valves the ideal, high-integrity solution for critical isolation and Emergency Shutdown (ESD) applications in hydrocarbon service.
🔑 Key Features and Design Advantages
Our Side Entry valves are preferred in the industry due to their inherent strength and superior sealing performance under extreme conditions:
Robust Trunnion Support: The trunnion-mounted design anchors the ball, absorbing pressure thrust and ensuring low, predictable operational torque even at maximum pressure ratings.
Zero Leakage Shut-Off: Designed and tested to exceed the most rigorous standards, providing consistent and reliable sealing (up to Class VI).
High-Pressure Capability: Capable of withstanding continuous operation at extremely high pressures, up to ANSI #2500 full rating.
In-Line Maintainability: The side entry construction often allows for easier access to the valve seats and seals, simplifying scheduled maintenance.
Firesafe Certified: Compliance with API 6FA ensures operational integrity and containment during external fire events.
