China Suppliers - Concentric Wafer Type Butterfly Valve with Aluminum Lever from Factory

China's wafer-type butterfly valves are essential fluid control equipment widely used in industrial pipelines. These valves are designed with a simple structure, making them compact, lightweight, and ideal for installations in tight spaces or where pipe distances are short. With a quick 90-degree rotation, they enable rapid opening and closing, ensuring efficient flow control with minimal fluid resistance. Ideal for various applications, these valves are commonly found in petroleum, gas, chemical industries, water treatment facilities, and cooling water systems in thermal power stations. As leading suppliers and factory manufacturers in China, we offer high-quality wafer-type butterfly valves that meet the demands of modern industrial operations.

Frequently Asked Questions

What is a resilient seated butterfly valve?

A resilient seated butterfly valve features a flexible rubber or elastomer seat that creates a reliable, bubble-tight seal against the valve disc, preventing leaks and ensuring excellent sealing performance in various pipeline systems.

What are the common applications for these valves?

Because of their versatility and reliable sealing, these valves are widely used across multiple industries including HVAC systems, water and wastewater treatment, food service, chemical processing, and fire control systems.

What is the difference between wafer and lug style body designs?

Wafer style valves are sandwiched between two pipe flanges, making them lightweight and cost-effective. Lug style valves feature threaded inserts (lugs) allowing them to be bolted directly to the flange, which makes them suitable for dead-end service and easier pipeline maintenance.

How do I choose the correct seat material?

Seat material selection depends heavily on the media, temperature, and pressure of your application. EPDM is excellent for water and HVAC applications, while materials like Viton or PTFE are preferred for handling harsh chemicals and higher temperatures.

Can resilient seated butterfly valves be automated?

Yes. Our butterfly valves come equipped with an ISO-5211 mounting pad and stem, making it simple to install pneumatic, electric, or hydraulic actuators for fully automated operation.

What maintenance is required for these valves?

Routine maintenance typically involves inspecting the rubber seat and disc for signs of wear or degradation, checking the actuator's functionality, and periodically cycling the valve to prevent the disc from sticking to the seat over time.
