The upper handwheel is controlled to open, and the inlet and outlet are flange type. Blue on the outside can also be made into other colors. The shell is made of ductile iron. The figure on the right shows an upright installation state, with the water inlet below. There are clear markings on the valve body indicating the direction of water flow, product specifications, diameter, and pressure rating

2、 How much does a multifunctional three in one check valve cost

The price of a multifunctional three in one check valve is mainly determined by the following factors:

1. Caliber, what is the required caliber. This caliber is usually the corresponding caliber of the pipeline. The inner diameter of the pipeline can be expressed in millimeters.
2. Pressure levels: There are three common pressure levels: 10 kilograms, 16 kilograms, and 25 kilograms;
3. Shell material: cast iron HT200 or cast iron QT450. Product starting price: DN50 three in one multifunctional check valve unit price is 220 yuan.

4、 Working principle of multifunctional three in one check valve

The multifunctional three in one check valve is a recommended valve for the outlet of the water pump. When the water pump stops working, it can quickly check back to prevent water hammer. When the pump is initially running, the valve disc opens due to the underwater thrust, and the valve opens. At the same time, the spring quickly closes under the spring force. As the water flow decreases and almost stops, the valve disc fully closes the three in one multifunctional check valve. There is no phenomenon of water reflux or backflow, which prevents the occurrence of water hammer as water does not reflux or backflow, resulting in no movement.

5、 Main technical parameters of multifunctional three in one check valve：

Installation and commissioning of multifunctional three in one check valve

1. Rotate the handwheel clockwise to cut off the conveyance of the medium.

The opening degree of the multifunctional three in one check valve can be adjusted to control the delivery of water volume.

3. The multifunctional three in one check valve supports the installation of both vertical and horizontal pipelines, and can function properly in both vertical and horizontal installations.

4. During installation, it is necessary to flush the pipeline. Pipeline flushing is a basic requirement for many pipeline equipment before installation. And install a filter, a T-shaped filter, in front of the valve.

5. It is necessary to keep the direction of water flow consistent with the direction indicated on the valve body of the multifunctional three in one check valve.
