Cast steel electric flange valve installation and maintenance

Many people do not quite understand that the installation and maintenance of cast steel electric flange valve are due to pay attention. Now, Huashan Valve will do an introduction for everyone to help you better understand the installation and maintenance of cast steel electric gate valve.

First of all, Z941H-16 cast steel electric flange valve installation and maintenance should pay attention to the following matters:

1. Handwheels, handles and transmissions are not allowed to lift, and collisions are strictly prohibited.

2. The double gate valve should be installed vertically (ie the valve stem is in the vertical position and the handwheel is at the top).

3. The gate valve with bypass valve should open the bypass valve before opening (to balance the inlet and outlet pressure difference and reduce the opening force).

4. The gate valve with transmission mechanism shall be installed in accordance with the product instructions.

5. Lubricate at least once a month if the valve is frequently used.

Z941H-16 cast steel electric flanged valve has the following advantages:

1. The fluid resistance is small, the sealing surface is affected by the brushing and erosion of the medium.

2. It is easier to open and close.

3. The flow direction of the medium is not limited, no spoiling, no pressure reduction.

4. Simple body, short structure length, good manufacturing process, and wide application range.

The disadvantages of the gate valve are as follows:

1. It is easy to cause erosion and scratches between the sealing surfaces, and maintenance is difficult.

2. Large size, opening requires a certain space, long opening and closing time.

3. The structure is more complicated.
