Pn16 ANSI 150lb BS5153 DIN Cast Iron Wcb Non-Return Swing Check Valve

Product Description

The swing check valve is a common type of check valve, which is characterized by the disc rotating around the axis outside the valve seat, and opening and closing are achieved by the swing of the disc. It is mainly used to prevent fluid backflow and is suitable for occasions with large flow and low pressure drop. The following is a detailed introduction to the swing check valve:
1. Working Principle
The disc of the swing check valve is fixed in the valve body by a hinge or shaft. When the fluid flows forward, the fluid pressure pushes the disc to open and allow the medium to pass; when the fluid stops or flows in the reverse direction, the disc closes quickly under the action of gravity or fluid reverse pressure to prevent the medium from flowing back.
 2. Main Features
- Low flow resistance: When the disc is fully opened, the flow channel is unobstructed and the fluid resistance is small.
- Wide range of application: It can be used for a variety of media such as water, oil, and gas.
- Simple structure: The disc and seat are simple in design and easy to maintain.
- High pressure resistance: It is suitable for medium and high pressure pipeline systems.
- Large flow: Suitable for large flow occasions, the valve disc has a large opening angle and the flow channel is unobstructed.
3. Application scenarios
Swing check valves are widely used in the following fields:
- Water supply system: Prevent water backflow when the water pump stops, protect the water pump and pipeline.
- Oil and gas pipelines: Prevent medium backflow and ensure pipeline safety.
- Chemical industry: Pipeline systems used for corrosive media, the material can be stainless steel or other corrosion-resistant materials.
- HVAC system: Prevent hot or cold water backflow and maintain normal operation of the system.
- Sewage treatment: Used in sewage pipes to prevent sewage backflow.
