Flange Stainless Steel DN150 Check Valve OEM 2500LB Pressure

Flanged Check Valves Introduction

Flange check valve is a valve that automatically opens and closes the valve disc by the flow of the medium itself to prevent the medium from flowing back. It is also called a non-return valve, a one-way valve, a reverse flow valve, and a back pressure valve. A check valve is an automatic valve. Its main function is to prevent the medium from flowing back, to prevent the pump and the drive motor from reversing, and to release the container medium. The check valve can also be used on the pipeline that provides supply to the auxiliary system where the pressure may rise to exceed the system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).

Check Valve Materials of main parts

Structural features of the check valve

1. Short structure length, its structure length is only 1/4~1/8 of the traditional flange check valve

2. Small size and light weight, its weight is only 1/4~1/20 of the traditional flange check valve

3. The valve disc closes quickly and the water hammer pressure is small

4. It can be used in horizontal or vertical pipelines and is easy to install

5. The flow channel is unobstructed and the fluid resistance is small

6. Sensitive action and good sealing performance

7. The valve disc has a short stroke and a small closing impact force

8. The overall structure is simple and compact, and the shape is beautiful

9. Long service life and reliable performance
