Reliable operation in order to ensure that the regulator, the regulating valve in use can take preventive maintenance measures, including adjusting valve in installation and use of a series of preventive measures, this can also be called daily maintenance, can generally through the following points,

1. The first checks to support and security situation
Install regulator is the best position to make the travel direction of the stem at the top of the actuator to the valve body in a vertical plane, if the regulator must be installed on the valve stem horizontal mobile location, or the movement of the valve stem direction and horizontal plane has a certain Angle, you should put actuator support, to make every parts of regulating valve in the natural state, and regulator of fixed and support measures, must be checked regularly, for use in explosive dangerous places the regulator and the related attachment should check the safe operation of the situation, for example, sealing cover are tight, the operation situation of safety barrier, power supply, etc., insures the safe running of the regulating valve and related accessories can,

(2) removal, to prevent foreign matter to enter
To check connections of regulating valve pipe presence of rust, welding slag, dirt, etc., found that after should keep clear of in time, if among the accumulation of the regulating valve and pipeline, the side valve upstream of the regulator should be considered easy to install the filter device, easy to penetrate in the process of medium hard sundry occasions, be sure to install a permanent filter, because the regulator in closing, a small piece of rust or welding slag was enough to destroy the valve seat sealing surface grinding well, affect the normal operation,

3. Preventive maintenance, check the source and power supply
Many occasions to dust covered with plastic or rubber around the valve stem packing box and the guide parts, presence of corrosive gas or liquid droplets occasions to the use of special protective measures, the commonly used anti-corrosion bag by the regulator, but should pay attention to not affect its operation, the pneumatic control valve of the film room although not consume air, but if the air supply system containing water, oil and other impurities, can make the valve positioner, the malfunction of the relay, and other attachment plug and must therefore be regular inspection on gas source and power supply, ensure the air clean, dry, reliable power supply,

4. Transport and warehousing
Regulator in the assembly and painting and install actuator as required, the handwheel, accessories such as locator, to prevent foreign matter into the regulator, connecting the regulator of all air interface to plug, connecting flange mount shield, to pay more attention to each connection, easy to damage any outstanding annex, the fitting should be removed, with regulator separate packing and transportation, regulator application special bracket, prevent loose, to ensure that the overall vertical position or a horizontal position, if the long distance transportation, had better use strong wooden shipment,
