Key Features:

1. Tilting Disc Design:

   • The valve features a tilting disc that pivots on a hinge or trunnion, allowing smooth and efficient flow in one direction while ensuring quick closure to prevent backflow.

   • The disc design minimizes pressure drop and turbulence, optimizing system performance.

2. Cylinder Actuator:

   • Equipped with a pneumatic or hydraulic cylinder, the valve can be remotely or automatically controlled.

   • The cylinder allows for precise opening and closing of the valve, enabling integration into automated systems and reducing the need for manual intervention.

3. Flanged Connection:

   • The flanged design ensures easy installation and secure connection to pipelines, making it suitable for high-pressure and high-flow applications.

   • Flanges are typically designed to meet industry standards (e.g., ANSI, DIN, or JIS) for compatibility with existing systems.

4. Reliable Sealing:

   • The tilting disc provides a tight seal even under low-pressure conditions, preventing leakage and backflow.

   • Optional bidirectional sealing is available for specific applications.

5. Durable Construction:

   • Made from high-quality materials such as stainless steel or carbon steel, the valve is designed to withstand harsh environments, including high pressures, temperatures, and corrosive fluids.

6. Quick Response:

   • The tilting disc and cylinder actuator work together to ensure fast closing action, reducing the risk of water hammer and protecting downstream equipment.

Applications:

• Oil and Gas: Used in pipelines and pumping systems to ensure unidirectional flow and prevent backflow.

• Water and Wastewater Treatment: Installed in pumping stations and distribution systems for reliable flow control.

• Power Generation: Utilized in cooling systems, steam lines, and condensate recovery systems.

• Chemical Processing: Suitable for handling corrosive fluids and maintaining flow direction in automated processes.

• Marine and Shipbuilding: Used in ballast systems and seawater applications where automated control is required.

Operation:

• When fluid flows in the correct direction, the tilting disc opens, allowing unimpeded flow.

• The cylinder actuator can be used to control the opening and closing of the valve, providing precise flow regulation.

• When flow stops or reverses, the disc quickly returns to its closed position, sealing the valve and preventing backflow.
