Use of The Product

1 The operating pressure shall not exceed the pressure in the product performance specification table and the operating temperature of the product.

2 When the valve is installed horizontally, the valve should be supported accordingly, especially to prevent the large-diameter valve driver from damaging the valve due to gravity.

3 When cleaning the pipeline, the valve should be in a fully open state.

4 Valves with cleaning pipes should be cleaned regularly (preferably once a week), and the specific cycle depends on the specific working conditions;

5 Take measures to prevent long-term violent vibration of the valve on the pipeline to avoid fatigue failure and leakage of the valve.

6 The valve must not replace the packing under pressure, and the upper sealing structure is not a reason for the user to replace the packing under pressure.

7 The design of this valve has not carried out life calculation, test and fatigue strength check, and the user must regularly check and replace it during use.

8 The design of this valve does not consider the seismic load, and the manufacturer is not responsible for the consequences caused by this.

9 The valve must be protected when installed in the open air.

10 During the use of the valve, the stem, stem nut and bearing should be lubricated once a week to ensure that the valve can be opened and closed flexibly.
