Stainless Steel Flange End Foot Check Valve
Stainless Steel Flange End Foot Check Valve - H42 Model
This stainless steel foot check valve, model H42, is designed for industrial use and is commonly installed at the bottom of pump suction pipes to prevent backflow of the medium into the water source. It features a flanged connection type, making it suitable for various piping systems. The valve operates under low pressure and is ideal for applications involving water or other industrial liquids.
Key Features:
- **Material**: Made from high-quality stainless steel, ensuring durability and resistance to corrosion.
- **Structure**: Lift-type design, which allows smooth operation and efficient flow control.
- **Function**: Acts as a check valve, preventing reverse flow when the pump is turned off.
- **Pressure Rating**: Available in PN 1.0, 1.6 MPa or 125lb, 150lb.
- **Size Range**: Suitable for DN32 to DN300.
- **Packaging**: Packed in wooden crates for safe transportation.
- **Origin**: Manufactured in Shanghai, China.
- **Trademark**: KQ – known for reliable quality and performance.
- **Certification**: Complies with ISO Quality Management System standards.
- **HS Code**: 8481804090.
The foot valve is equipped with multiple inlet holes and reinforcing ribs on the cover, reducing the risk of clogging and improving overall efficiency. It is widely used in industrial applications, including water treatment, oil, and chemical processing.
**Working Principle**
The foot valve consists of a cover, disc, bushing, and seal ring. When the pump is running, the flowing medium opens the disc, allowing fluid to pass through. Once the pump stops, the pressure in the outlet pipe closes the disc immediately, preventing any backflow. This mechanism ensures smooth pumping and minimizes water loss.
