WCB Two-Piece Flanged Floating Ball Valve

Zhongguan Valve's WCB Two-Piece Flanged Floating Ball Valve utilizes a mature two-piece bolted connection structure, designed to provide a highly reliable shut-off and control solution for industrial piping networks. As a seasoned WCB ball valve manufacturer, we produce ball valves ranging from DN15 to DN600, supporting various flange sealing surfaces such as RF, FF, and RTJ.

The Zhongguan Valve WCB Two-Piece Flanged Floating Ball Valve is a typical 90° angle opening and closing device. Its two-piece design allows for maintenance of the internal seals and ball by removing the side bolts without affecting the overall pipeline structure, effectively reducing system operation and maintenance costs.

Core Design Features: Split-piece structure: The WCB Two-Piece Flanged Floating Ball Valve body consists of a main valve body and a secondary valve body, facilitating maintenance and parts replacement.

Floating Ball Design: Under medium pressure, the ball shifts and presses firmly against the sealing ring at the outlet, ensuring reliable sealing performance.

Anti-Blowout Stem: The stem features an inverted design to prevent blowout during abnormal pressure increases, enhancing operational safety.

Diverse Standards: Supports multiple standard systems such as ANSI, DIN, and GB, meeting engineering needs in various regions worldwide.

4. Why Choose Zhongguan Valve?

19 Years of Industry Experience

We have over 19 years of experience in valve manufacturing, with two major production bases in Tianjin and Wenzhou. The Tianjin base focuses on the northern water conservancy valve supply chain (primarily cast iron materials), while the Wenzhou base, located in northern China's "Pump and Valve Capital," focuses on the southern industrial valve supply chain (primarily cast steel and stainless steel).

Strict Quality Inspection System

We insist that every WCB Two-Piece Flanged Floating Ball Valve must pass the following tests before leaving the factory:

1.5x Strength Test: Ensures no deformation or leakage in pressure-bearing components.

Sealing Performance Test: Performs dual airtightness and watertightness tests according to standards to achieve zero leakage.

Operating Torque Verification: Ensures smooth operation after on-site installation, extending actuator life.

Deep Customization Services

Special Operating Conditions: Stainless steel (CF8/CF8M) materials are available to withstand highly corrosive environments.

Installation Optimization: Extended valve stem design is available for buried pipelines.

Safety Protection: Optional handle with locking device to prevent accidental operation.

Manufacturing Equipment and Technological Advantages

We possess a complete production line, including precision CNC machine tools, large valve pressure testing machines, specialized equipment for bushing installation, and a fully automated spraying line. This ensures that the machining accuracy of the WCB two-piece flanged floating ball valve is controlled at the micron level, thereby improving the fit between the valve seat and the ball and reducing operational wear.

Frequently Asked Questions (FAQ)

Q: What is the difference between WCB and stainless steel materials? 

A: WCB is a carbon steel material, suitable for non-corrosive industrial media (such as water, oil, steam), with high strength and cost-effectiveness; stainless steel (such as CF8/CF8M) is mainly used for highly corrosive media such as acids and alkalis.

Q: Can your ball valves be matched with automatic actuators? 

A: Yes. Our WCB two-piece flanged floating ball valve can be equipped with a high-platform design conforming to ISO 5211 standards, facilitating direct installation of pneumatic or electric actuators.

Q: What is the typical service life of a ball valve? 

A: Under standard operating conditions, our valves are designed for a service life of over 10 years. Furthermore, due to their two-piece design, replacement of wear parts (such as seals) is simple, greatly extending the overall service life.
