4-inch Trunnion Ball Valve Core

This API 6D trunnion-mounted ball valve core is designed for long-distance pipelines and oil-gas processing stations. The core surface undergoes Electroless Nickel Plating (ENP) for superior corrosion resistance. Its trunnion structure effectively distributes fluid pressure loads on the seals, ensuring low operating torque even at 5,000 psi. Combined with precision grinding technology, this core maintains tight sealing integrity over thousands of cycles, making it a cornerstone of industrial fluid control systems.
