Design Details: Trunnion mounted ball valves are designed in accordance with API6D. A trunnion ball valve has additional mechanical anchoring of the ball at the top and the bottom making them more suitable for larger and higher pressure pipelines. All valves are equipped with vent and drain lines (Double Block and Bleed), and sealant lines for both stem and seats to allow external intervention to prevent seat or stem leakage.
