Principle of h62f double by-pass PVC check valve:

1. Model h62f double by PVC check valve principle size: 1/2 "- 2", interface mode: tooth mouth, flat mouth.

2. Standards: ANSI sch80 (American Standard), BS (British Standard), DIN (German standard), JIS (Japanese standard), Thailand standard (Thai Standard), CNS (Taiwan standard)

3. Model h62f double by PVC check valve has 6 characteristics:

a. The product has obtained NSF National Health Association certification and passed ISO 9001:2008 quality certification.

b. The model h62f double by makes the PVC check valve have exquisite appearance, smooth surface, fine processing and full flow design.

c. The valve is made of all plastic, non rusting and anti-corrosion. When assembling the valve, it does not use any silicone lubricant, which is hygienic and non-toxic, and can be applied to most media.

d. Model h62f double by PVC check valve EPDM sealing ring, with good sealing performance and strong corrosion resistance.

e. The two-way double command design is convenient for maintenance. When the equipment pipeline in the front section does not have to stop working, the ball valve can be closed, the command can be removed, and the engineering maintenance in the rear section can be carried out.

f. Model h62f double by PVC check valve can be quickly assembled with special tools, and the loading and unloading are simple.

g. Model h62f double by PVC check valve vertical installation, flow from bottom to top, when installing, please identify the direction of the arrow, that is, the direction of fluid flow.

4. The products are widely used in chemical industry, electronics, metallurgy, electroplating, irrigation, sewage treatment, circulating water engineering, aquatic products breeding, civil construction and other industries.

5. Model h62f double by PVC check valve principle:

Model h62f is a valve that automatically opens and closes the valve disc by making the PVC check valve flow itself, which is used to prevent medium backflow. It is also known as check valve, one-way valve, reverse flow valve, and back pressure valve. Model h62f double by PVC check valve principle belongs to an automatic valve, which is mainly used to prevent medium backflow, reverse rotation of pump and drive motor, and discharge of container medium. The check valve can also be used to supply the auxiliary system whose pressure may rise above the system pressure.

The function of this type of valve is to allow the medium to flow in only one direction and prevent the reverse flow. The valve works automatically. Under the pressure of fluid flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the fluid pressure and the self weight of the valve disc act on the valve seat to cut off the flow.

The main function of plastic spring check valve is that the water hammer pressure is very small, the valve clack stroke is short, the valve clack is light, and it has spring assisted closing, and the closing speed is very fast. The structure is short in length, small in volume and light in weight, which brings great convenience to the installation, handling, storage of valves and the layout of pipelines, and can save a lot of materials and reduce the cost.
