Product Specification

Titanium Electric V-Port Ball Valves: Gr1 and Gr2, 8-Inch, Class 150, DN 15-250 for Water Supply

Product Introduction:

A ball valve regulates fluid flow by rotating a spherical ball with a central hole. Renowned for its straightforward design, ease of operation, and exceptional sealing capabilities, the ball valve is extensively used in industrial pipeline systems across oil, natural gas, chemicals, power generation, and water treatment sectors. Key features include:

• Quick Operation: 90-degree turn for fast open/close action.
• Reliable Sealing: Effective sealing even under high pressure and temperature.
• Durability: Long-lasting performance due to high-quality materials for the ball and seal.
• Minimal Fluid Resistance: Especially with full bore designs.
• Versatile Connections: Available in flanged, threaded, and welded options.

Ball valves are integral to industrial production, public utilities (e.g., water supply and HVAC systems), and automated control systems when paired with electric or pneumatic actuators. They can be categorized by structure (e.g., floating, trunnion-mounted, and resilient-seated), bore type (full bore and reduced bore), and stem design (top-entry and side-entry). They are made from various materials including stainless steel, carbon steel, brass, and titanium alloys, selected based on specific operational conditions and media. Overall, ball valves are essential for optimizing system efficiency and ensuring reliable and safe operations in both industrial and civilian applications.

A floating titanium ball valve features a ball that is not fixed but allowed to float within the valve body. This design allows the ball to move slightly under pressure, ensuring a tight seal against the outlet end’s sealing surface.

Main Features of Ball Valves:

• Minimal Fluid Resistance: The resistance coefficient is equivalent to that of a pipe segment of the same length.

• Simple Structure, Compact Size, Lightweight: Ball valves are designed for ease, being both compact and lightweight.

• Reliable Sealing: Ball valves commonly use plastic materials for sealing surfaces, offering excellent sealing performance and suitability for vacuum systems.

• Ease of Operation: A 90° rotation is all that is needed to fully open or close the valve, allowing for efficient remote control.

• Convenient Maintenance: The straightforward design and removable sealing rings facilitate easy disassembly and replacement.

• Isolation of Sealing Surfaces: When fully open or closed, the ball and valve seat sealing surfaces are isolated from the medium, preventing erosion during passage.

Applications of Three-Way Titanium Ball Valves:

Three-way titanium ball valves find diverse applications across various industrial sectors due to their unique properties:

• Chemical Industry: With titanium's excellent corrosion resistance, these valves are ideal for managing corrosive substances such as acids, alkalis, and oxides in chemical production processes.

• Aerospace Field: Thanks to their lightweight and high-strength characteristics, three-way titanium ball valves are widely used in aerospace hydraulic and fuel systems, meeting the demanding requirements of aircraft.

• Food and Pharmaceutical Industries: Titanium's non-toxic nature and lack of contamination make these valves a preferred choice for fluid control in food processing and pharmaceutical applications.

• Petroleum and Natural Gas Industry: They are essential in controlling the flow and pressure of fluids during the extraction, transportation, and processing of petroleum and natural gas, ensuring system safety and stability.

• Marine Engineering: Their resistance to seawater corrosion makes them suitable for marine applications, including fluid control systems in subsea pipelines and offshore platforms.

Common Connection Methods for Titanium Ball Valves:

• Flange Connection: Ideal for medium to high-pressure systems, this method uses flanges and bolts to join the valve and pipeline, offering robust sealing, reliability, and ease of disassembly for maintenance.

• Threaded Connection: Best suited for small-diameter, low-pressure systems, threaded connections (e.g., NPT, BSP) are simple and easy to use but are not recommended for frequent disassembly.

• Welded Connection: Available as butt-welded or socket-welded, this method is used for high-temperature, high-pressure, and corrosive media systems. It provides a permanent, leak-proof connection and is ideal for applications requiring maximum sealing and stability.

• Quick-Connect Couplings: These allow for rapid assembly and disassembly, making them suitable for applications with frequent installation and removal needs, though they are generally used for low-pressure systems.

• Clamp Connection: Utilizing clamps to attach the valve to the pipe, this method is preferred for high sanitary requirements, such as in the food and pharmaceutical industries, and allows for easy assembly and disassembly without special tools.

• Socket Connection: This involves inserting the pipe into the valve's socket end and securing it by welding or bonding, suitable for small-diameter systems, offering good sealing and mechanical strength.
