3 piece trunnion mounted ball valves are designed manufactured to provide maximum service life and dependability. All ball valves are full ported and meet the design requirements of American Petroleum Institute standard API 608&API 6D British standard BS 5351 and generally conform to American society of Mechanical Engineers standard ASME B16.34 valves are available in a complete range of body/bonnet materials and trims.
The 3 Piece trunnion mounted ball valves with Spring Return Pneumatic Actuator is engineered for precise flow control in various industrial applications. This valve is equipped with a trunnion-mounted ball, ensuring stable operation even under high-pressure conditions. The three-piece design allows for easy maintenance and installation, making it a reliable choice for complex piping systems. The integrated spring return pneumatic actuator offers automated control, ensuring the valve returns to its default position upon loss of air supply, enhancing safety and operational efficiency.
This valve is ideal for industries such as oil and gas, petrochemical, and power generation, where reliable and responsive flow control is essential.
This forged steel 3-Piece Trunnion Mounted Ball Valves are ideally suited for pipeline and other applications within the global energy infrastructure where zero leakage positive shutoff is critical. API Monogrammed and compliant with all relevant industry specifications, C&C trunnion mounted ball valves are an ideal component to any piping network.
