Direction for use

1 The valve is the indispensable valve is industry pipeline,please pay attention to the symble of the valve and the nameplate if them accord with the working demand. 

2 .Make sure that the valve is clean and the default caused during the delievery has been solved  before installation.

3.Be sure that the valve be clean after installation, oil should be put in periodically
