Frequently Asked Questions
-
What is the dual-drive operation feature in this ball valve?The dual-drive operation combines an electric actuator for automated control and a worm gear for manual operation during emergencies. This ensures the valve remains fully controllable under all conditions, including power failures or system malfunctions.
-
What are the advantages of the top entry design?The top entry design allows technicians to inspect, repair, and maintain the valve without removing it from the pipeline. This significantly reduces system downtime, lowers maintenance costs, and simplifies servicing in confined or hard-to-reach installations.
-
Why is a trunnion-mounted ball design preferred for high-pressure applications?A trunnion-mounted ball design mechanically anchors the ball at both the top and bottom, ensuring stable pressure distribution across the valve. This makes it ideal for high-pressure and large-diameter pipeline applications where floating ball designs may not provide sufficient support.
-
How does the bi-directional sealing ensure leak-free performance?The bi-directional sealing mechanism creates a tight seal regardless of the flow direction. It maintains consistent, low-torque operation even under extreme pressure conditions, preventing any fluid or gas leakage and ensuring long-term reliable performance in critical pipelines.
-
What materials are available and what sizes does this valve come in?This valve is available in sizes ranging from 2" to 64", covering a wide range of pipeline requirements. Material options include ASTM A216 WCB carbon steel, Stainless Steel, and Duplex stainless steel, making it suitable for corrosive, high-temperature, and chemically aggressive environments.
-
How does the emergency shutoff feature enhance pipeline safety?The built-in emergency sealing device activates quickly during critical situations such as sudden pressure surges or system failures. It provides an immediate leak-free seal, minimizing the risk of hazardous fluid or gas release and ensuring the safety of personnel and infrastructure.
