UD Series soft sleeve seated butterfly valve is Wafer pattern with flanges ,the face to face is EN558-1 20 series as wafer type.

U-shaped butterfly valve is a type of rubber seated butterfly valve, which is characterized by a unique U-shaped valve disc design. This design allows smooth, unimpeded flow of fluid through the valve, minimizing pressure drop and reducing energy consumption. The rubber seat on the disc ensures a tight seal, preventing any leakage and ensuring efficient operation of the valve. U-shaped butterfly valves are often used in situations where strict closing and reliable sealing are required. It is suitable for use with a variety of fluids, including water, natural gas, petroleum and chemicals.

One of the main features of the U-shaped concentric butterfly valve is its simplicity and ease of operation. It fully opens or closes the valve by rotating the disc through a 90-degree angle. The disc is connected to the valve stem, which is operated by a lever, gear, or actuator. This simple mechanism makes the U-shaped butterfly valve easy to install, operate and maintain. In addition, the valve’s compact size makes it suitable for installations with limited space.

U-shaped resilient butterfly valves are used in a variety of industries, including oil and gas, water treatment, chemical processing, power generation and HVAC. In the oil and gas industry, it is commonly used in pipelines that control the flow of crude oil, natural gas, and other petroleum products. In water treatment plants, U-shaped butterfly valves are used to regulate water flow in various treatment processes. In chemical processing plants, valves are used to control the flow of different chemicals. In power plants, it is used to control the flow of steam and other fluids. In HVAC systems, U-shaped butterfly valves are used to control the flow of air and water in heating and cooling systems.

U-shaped butterfly valve is a versatile and reliable valve that is widely used in various industries. Its unique U-shaped disc design and rubber seat ensure a tight seal and smooth fluid flow. The valve is easy to operate and maintain and is widely used in the oil and gas, water treatment, chemical processing, power generation and HVAC industries. Whether controlling the flow of water, air, oil or chemicals, U-shaped butterfly valves have proven to be an efficient and effective solution.

Characteristics:

1.Correcting holes are made on flange according to standard, easy correcting during the installation.
2.Through-out bolt or one-side bolt used. Easy replacing and maintenance.
3.The soft sleeve seat can isolate the body from media.

Product operation instruction

1. Pipe flange standards should conform to butterfly valve standards; suggest using welding neck flange, specialized flange for butterfly valves or integral pipe flange; do not use slip-on welding flange, supplier must agreed before user can uses slip-on welding flange.
2. The use of pre-installation conditions should be checked whether the use of butterfly valves with the same performance.
3. Before the installation user should clean the sealing surface of valve cavity, make sure no dirt attached; simultaneously clean the pipe for welding slag and other debris.
4.When installing, the disc must be in closed position to ensure that the disc do not collide with the pipe flange.
5. Both valve seat ends act as flange seal, extra seal is not needed when installing the butterfly valve.
6. The butterfly valve can be installed at any position (vertical, horizontal or tilt). Butterfly valve with big size operator may need bracket.
7. Collide when transporting or storing the butterfly valve may cause butterfly valve reduce its sealing ability. Avoid butterfly valve disc from bumping to hard objects and it should be open at 4 ° to 5 ° angle position in order to maintain sealing surface from damaging during this period.
8. Confirm correctness of flange welding before installation, welding after installation of the butterfly valve may cause damage to the rubber and preservation coating.
9. When using butterfly valve operated by pneumatic, the air source should maintain dry and clean to avoid foreign bodies from entering pneumatic operator and affect working performance.
10. Without special requirements noted in purchasing order of the butterfly valve can only be mounted vertically and for interior use only.
11. Case of disorder, reasons should be identified, troubleshooted, should not knock, hit, prize or lengthen the lever operator by arm of force to forcibly open or close the butterfly valve.
12. During the storage and unused period, the butterfly valves should kept dry, sheltered in shade and avoid harmful substances surrounding from erosion.
