Forged Steel Gate Valve

1. Before installation, check the valve name plate and valve body information to ensure the valve is suitable for the intended service.

2. Before installation, remove the flange cover and the protective film on the flange sealing face, inspect the bore and the flange sealing surface, remove any dirt with a clean soft cloth, use an anti-corrosive cleaning liquid to clean if necessary, and never use any other chemical products.

3. Inspect the flange gasket (including ring gasket) sealing surface and ensure it is in acceptable condition for installation.

4. After cleaning the valve and before installation, open and close the valve one time. Ensure the valve operates smoothly. If abnormal operation is experienced, stop the operation and inspect the valve stem and valve bore for any obstructions that may be preventing normal operation.

5. After successfully cycling and assuring the proper operation of the valve, return the valve to the closed position until installation is complete. If for any reason the valve must remain in the open position, ensure the valve sealing surfaces are protected.

1. Position the valve into the pipe or the flange connection; ensure that any stress caused by improper pipe alignment is relieved first. Valves are not intended to be a means of aligning improperly fitted pipe.

2. Install the valve using qualified piping standards and practices. Valves marked with flow direction must be installed in line with the piping flow.

3. The recommended orientation for slab conduit gate valves is upright with the valve in a horizontal line with the hand wheel positioned vertically above the valve centerline.
