    CS400 Pressure Reducing Regulators

    Application

     

    The CS400 Series direct-operated, spring-loaded regulators have been engineered to fit a multitude of pressure reducing applications including commercial and industrial installations. It can be used for natural gas, artificial gas, liquefied petroleum gas, air and other gases. With its stable performance, large film pressure regulating, high pressure regulating precision, it is very suitable for combustion machines, burners and other direct combustion equipment.


    Main features

     

    • Material: Cast Aluminum+Cast iron

    Springs: Steel

    Diaphragms: Synthetic Rubber

    Operating temperature:  -20~60

    Connection : Threaded connection


    Principle of Operation

     

    Through the action of the pusher post assembly, lever and valve stem, the valve disk moves closer to the orifice and reduces gas flow. If demand downstream increases, pressure under the diaphragm decreases. Spring force pushes the pusher post assembly downward, the valve disk moves away from the orifice and the gas flow increases downstream as the regulator opens in response to the decreased pressure underneath the diaphragm.

    Installation notice

    The CS400 Series regulators may be installed in any position. However, the spring case vent should be pointed downward. If the vented gas will be piped to another location, use obstruction-free tubing or piping at least equal in size to the vent and the end of the vent pipe must be protected from anything that might clog it. 

    Before installation, the pipe shall be purged to clean the impurities in the return stroke of the pipe, so as to prevent impurities from entering into the valve cavity and causing the voltage regulator can not work normally.

    During installation, the air flow direction shall be the same as the arrow direction marked on the valve seat.


    Pressure adjustment:

     

    After the installation, screw down the plastic cover on the valve body, and then use a  screwdriver to adjust the pressure spring cover inside, clockwise rotation, export pressure increases, counterclockwise rotation, export pressure decreases.


    Maintenance


    Regularly check whether the pipeline is blocked, and check the pressure gauge in front of the pressure reducing valve to ensure it is working normally etc.

    To remove the dirt periodically . If there is problem with the regulator, please contact the manufacturer for feedback and support, and conduct for maintenance and testing if necessary. Use of a relief valve upstream or downstream of these regulators is recommended.


    Warning!

    All installation and maintenance operation must be carried out solely by qualified personnel!
