What are the types of control valve

        The control valve is composed of two main components: valve body assembly and actuator assembly (or actuator), divided into four series: single seat control valve, double seat series seriescontrol valve, sleeve series control valve and self control valve series.

       Four types of valve variants can lead to many differentapplications of the structure, each structure has its special application, characteristics, advantages and disadvantages.Although some control valve than other valve has wideapplication, but the control valve does not apply to all conditions,to construct the enhanced performance, reduce the cost optimal solutions.

     Type

    Control valve body types, commonly used through single seat,through two seater, angular, diaphragm, small flow, three links,eccentric rotation, butterfly, sleeve type, ball and so. In thespecific choices, do the following considerations:

    The main consideration based on the choice of flow characteristics and unbalanced force.

When the fluid medium is a suspension of high concentration of abrasive particles, hard materials to the internal valve.

    As the medium is corrosive, as we choose simple valve.

    When the medium temperature, high pressure and great change,should choose the valve core and valve seat materials,temperature, pressure changes in the small valve.

     The flashing and cavitation produced only in liquid medium. In the actual production process, steam and air will form a vibration and noise, shorten the life of the valve, so the choice of valve should be to prevent the valve steam and cavitation.
