Regulating valve many times often caused by the quality in used, not because the regulator itself but the regulating valve installation that caused by improper use, such as installation environment, installation position and direction due to reasons such as caused by improper or line is not clean. So the regulator in the installation should pay attention to when using the following aspects:

1. the regulator belongs to the field instruments for environmental temperature should be in 25 ~ 60 ℃, relative humidity 95% or less. If it is installed in the open air or high temperature applications, waterproof, cooling measures should be taken. Where there is the source to stay away from source or increase the antivibration measures.

2.the regulator shall generally be installed vertically, special circumstances can tilt, such as the Angle is very big, or too much weight on the valve when the valve itself should increase support protection.

3. install regulator pipe generally do not too high above the ground or floor, height is greater than 2 m in pipe should try to set up the platform, facilitate the handwheel operation and easy maintenance.

4. the regulator before installation for pipeline cleaning, eliminate dirt and welding slag. After installation, to ensure that no residue in the body, should also again to the valve and clean, the access into the medium should make all open valve, in order to avoid impurity stuck. After using the handwheel institutions, should be restored to the original neutral position.

5. in order to make the valve in case of failure or repair can continue to make the production process, the regulator should add by-pass pipe, at the same time also should pay special attention to, the regulating valve installation position whether accord with the requirement of technological process.
