Install regulator should pay special attention to the following:
(1) regulating valve should be installed in horizontal pipe runs vertically, in special cases need level and tilt when installation, generally to increase support,
(2) when the nominal diameter of regulating valve and pipe diameter is not at the same time, should connect with sloper,
(3) the installation site should have good environmental conditions and environmental temperature should be in 25 ~ 55 degrees,
(4) avoid installed in places that have requirements of vibration source, otherwise necessary antivibration reinforcement measures should be taken,
(5) when installation, must make the arrow on the body or flange pointing in the direction of medium,
(6) before the installation, it is necessary to carefully remove the pipe welding slag and other sundry; After the installation, should make the valve core is in the biggest opening, and the pipe and valve cleaning again, prevent sundry jam and damage the throttling parts,
(7) pneumatic control valve should be installed in easy to maintain, repair,
Straight pipe (8) before the valve should be as long as possible,
(9) export piping application 3 ~ 5 pipe diameters of straight pipe,
(10) in order to ensure that the regulator and regulating system failure does not affect the production and safety accidents occur, are generally need to install the bypass and the bypass valve, regulating valve, the cut-off valve installation, for high temperature, high pressure, easy cold, viscous medium, and the installation guide deluge valve, bypass valve cannot be installed in the valve, in order to avoid the bypass valve leakage to the regulator of corrosive medium,
