Waits Valve U-Type Recirculating Water Butterfly Valve is a manufacturer, factory, and supplier of automatic recirculation valves used for pump protection. The automatic recirculation valve used for pump protection is a multifunctional valve whose main purpose is to always pass through the predetermined minimum flow rate of the centrifugal pump. This is very important because centrifugal pumps can overheat, corrode, and cause permanent damage when idling. The automatic recirculation valve or automatic flow check valve used for pump protection is a special form of lift check valve installed downstream of the boiler feedwater pump. Achieve minimum flow during low flow operation.
The Waites valve durable U-Type Recirculating Water Butterfly Valve is a type of valve whose butterfly valve disc is mounted on a rod located between two flanges. The valve disc rotates around the rod to open or close the valve. These valves are commonly used in multiple industries such as chemical, pharmaceutical, and food processing. If you want to learn more about U-shaped butterfly valves, then you have come to the right place. We are a professional valve supplier

The U-Type Recirculating Water Butterfly Valve is widely used in various occasions due to its versatility and efficiency. They are commonly used in situations involving the flow of liquids and gases, including water treatment, chemical processing, and food and beverage processing. They are also used in HVAC systems, marine applications, and fire protection systems.

In water treatment plants, the U-Type Recirculating Water Butterfly Valve is used to control the flow rate of water at various stages of the treatment process. In chemical processing plants, they are also used to control the flow of chemicals at different stages of the production process.
In food and beverage processing plants, the U-Type Recirculating Water Butterfly Valve is used to control the flow of liquid in pipelines and storage tanks. They are highly suitable for such applications as they are easy to clean and maintain, and can handle liquids of different viscosities.

Automatic recirculation valve pump protection function
1. The automatic recirculation valve is driven by its own medium and is the minimum flow protection device of the centrifugal pump.
2. Cast steel and forged steel valve bodies
3. Pipeline connection: flange
4. Completely mechanical structure, relying on its own medium to control the valve, energy-saving and low-cost.
5. The main circuit has a check valve function.
6. It has the function of a flow sensor.
7. The bypass adopts a multi-stage vortex pressure reducing structure, which is resistant to cavitation and erosion.
8. Leakage level: ANSI V
9. DN25~DN300,PN6.4~32MPa,Class 300~2500LB
