Installation

The key point of valve service life is valve installation. Improper installation may reduce valve performance. If proper attention is paid during installation, the reliability of valve operation will be improved. It is very important to confirm whether the valve is in good working condition before the valve is installed. The following common requirements are helpful to avoid subsequent problems of the valve.

a. Remove valve protective articles carefully and check the objects and labels.

b. Attention must be paid to the special warning labels attached to or along with the valves and appropriate measures must be taken.

c. Check the flow direction sign of the valve. If the flow direction is indicated, the valve should be installed according to the flow direction.

d. Installation should clean the inner cavity and sealing surface, check whether the packing is tightened and whether the connecting bolts are tightened evenly.

e.Valves should be installed in accordance with the allowable working position, and attention should be paid to the convenience of maintenance and operation.

f. Rotating the handwheel when opening or closing, it is not advisable to use other auxiliary levers.

g. If it is feasible to conduct open-close-open cycle operation through the valve operator to check whether the valve performance is normal, but avoid valve damage in operation;

h. Before installing the valve, check whether the pipeline connected with the valve is positioned correctly, and whether it is clean.

i. After installation, regular inspection should be carried out to remove the dirt in the inner chamber, check the sealing surface and check the wear and tear of the stem nut.

Notes

1. Unless valves need to be inspected and installed,it is recommended not to remove the valve cover. 

2. If the valve must be placed outdoors,it should be supported without contact with the ground or road surface and protected by a waterproof cover.
