A Ball Valve is a type of flow control device commonly used to regulate the flow of liquids or gases through a pipeline. It operates by using a spherical disc (the "ball") that has a hole through the center. When the valve is open, the hole aligns with the flow direction, allowing fluids to pass through. When the valve is closed, the ball is rotated so that the hole is perpendicular to the flow, blocking the passage and stopping the flow.

From high temperatures to shield tunneling, NDV's special ball valves meet all challenges.

The NDV special application ball valve series is designed to address various processes according to strict environmental conditions or specific requirements. This series includes high-temperature valves, metal-seated ball valves, Y-type 3-way ball valves, ball valves for shield tunneling, and top-entry ball valves.

Types of Special Application Ball Valves
High-Temperature Valves: Suitable for use in extreme high-temperature environments. They are made with heat-resistant materials, providing stable performance.
Metal-Seated Ball Valves: Ideal for environments requiring high durability and longevity. The use of metal seats achieves excellent sealing performance under high temperature and pressure.
Y-Type 3-Way Ball Valves: Optimal for fluid direction change or mixing. A single valve can perform multiple functions.
Ball Valves for Shield Tunneling: Special valves used in shield tunneling methods for tunnel construction. They are designed to withstand tough working environments.
Top-Entry Ball Valves: Feature an easy maintenance design. Internal parts can be replaced or maintained without disassembling the valve body.

Applications
The NDV special application ball valve series is suitable for use in various industrial sectors, including energy, chemicals, mining, and construction. Each valve is optimized for specific processes or environmental conditions, ensuring efficient and reliable fluid control.

These valves utilize advanced technology and innovative designs to meet the needs of projects facing specific challenges or environmental conditions. With NDV's special application ball valves, optimal performance and durability are assured in any situation.
