1, should be installed in horizontal pipe runs vertically, in special cases need horizontal or inclined installation, general should increase support, from the carton board and wall of heat preservation box should be parallel to the wall of the garden,
2, should be installed near the ground or floor, so that lies in the maintenance, the fitted with valve positioner or the handwheel institutions, should guarantee the observation, adjustment and operation and convenience,
3, usually set the by-pass line, in order to switch to the automatic control system failure or maintenance regulator with manual operation, not to stop production,
4, equipped with a handwheel, also can be omitted by-pass line: manual operation, also can be used to limit the opening of the valve, when to stop using the handwheel institutions must be restored to its original neutral position, and automatic control system on the rails,
5, when installation, should make the medium flow in direction indicating valve body,
6, regulator to deal with pipeline cleaning dirt before installation, welding slag, after installation, the valve fully open, the pipeline, valve, etc for cleaning and testing of each joint sealing,

Low temperature regulating valve by pneumatic diaphragm actuators and low temperature resistant, two-seat valves in two parts, the regulator to the signal input pneumatic diaphragm actuator air chamber pressure, generate thrust, by connecting rod drives the valve core, valve core position changes make the valve flow, cross-sectional area changes of medium flow rate adjustment,

Low temperature regulator is single, two-seat regulator deformation of the product, it is different from normal temperature regulator is adopted on the long neck type bonnet, makes the packing work at room temperature, suitable for 60 ~ 250 degrees low temperature of the medium under strong condition (such as liquid oxygen, liquid nitrogen, etc.) of adjustment, in order to ensure the accuracy, must with the valve positioner,
