Wafer Butterfly Valve

Wafer Butterfly Valve

Wafer-style butterfly valve, a 90-degree rotary flow control valve for industrial pipelines

Wafer-Type Rubber-Lined Butterfly Valve

The wafer-style vulcanized butterfly valve represents an outstanding example of integrated seat and body design. Utilizing an advanced high-temperature, high-pressure vulcanization process, high-performance rubber is securely bonded to the valve body's inner cavity and the disc's outer surface, completely isolating the medium from metal components—making it particularly suitable for highly corrosive applications. This vulcanization process effectively eliminates common issues found in traditional valves, such as seat stretching, deformation, and detachment during frequent cycling. The seamless bond between the seat and body not only enhances sealing stability but also significantly reduces friction between the disc and seat as well as operating torque, thereby extending the valve's service life.

Wafer-Type Soft-Seated Butterfly Valve

The Wafer-Type Soft-Seated Butterfly Valve is a cost-effective, easy-to-maintain valve featuring a soft seal. It utilizes a detachable, core-less (soft-backed) rubber seat design with a tongue-and-groove configuration; this ensures the seat is securely anchored to the valve body—preventing deformation—while also facilitating convenient in-line replacement. Its lightweight wafer-style structure, excellent sealing performance, and ultra-low operating torque make it a preferred choice for fluid control and water system piping. It is widely used in water treatment plants, power plants, steel mills, and the paper, chemical, and food industries for water supply, drainage, and gas pipeline applications.

Wafer-Type Backrest-Seated Butterfly Valve

The Wafer-type backrest-seated butterfly valve is a compact, mid-performance fluid control solution. It is a robust industrial valve designed specifically for demanding operating conditions. By rotating an internal disc to regulate flow or provide shut-off, the valve functions as a precision on/off switch within piping systems. Its hard-backed seat design effectively prevents deformation and reduces operating torque, thereby significantly extending service life in harsh environments. For systems transporting clean water or air at ambient temperature and pressure, the concentric hard-backed soft-seated wafer butterfly valve offers a more cost-effective alternative.

FAQ

Frequently Asked Questions

How do I scientifically select the right valve?

Selection requires a comprehensive assessment of operating conditions, fluid characteristics, and pressure requirements. You must determine the valve's function—whether for shut-off, regulation, or check (non-return) purposes—to match it with the most suitable type and material, ensuring it meets system needs.

What should I do if a valve leaks during operation?

If a leak is detected, immediately shut off the flow of the medium. Inspect the gaskets, seals, and check for any debris. Contact the manufacturer for repairs regarding seal issues; serious faults, such as valve body cracks, require replacement or professional after-sales handling.

What is the typical lead time for custom (non-standard) valves?

Standard models are available from stock. Custom orders typically take 15 to 45 days, depending on complexity. For urgent orders, we recommend communicating in advance so the manufacturer can coordinate expedited production.

How should the correct valve material be selected?

The selection is based on the corrosiveness of the medium and the temperature.For highly corrosive environments, 304 or 316 stainless steel is recommended; for conventional media such as water, oil, and gas, cast iron or carbon steel can be used, balancing cost and operating conditions.

What does the manufacturer's after-sales service usually include?

Services cover selection guidance, installation and commissioning, and warranty repairs. Top-tier manufacturers provide rapid response times and on-site support to ensure stable production operations.
