General information Self-operated Pressure Controller Type PCV 39-02 Self-operated Pressure Controller Type PCV 39-02
Self –Operated pressure control valve is a useful device to fix pressure of line on an adjusted set point. Its adjustable pressure range is 0.2…6 bar and size varies from DN15 to DN80. Its nominal pressure is PN16 or PN25 and its maximum temperature is 350°C. This device is made based on DIN standards. 39-02 valve is useful for steam lines.

Function Self-operated Pressure Controller Type PCV 39-02 Self-operated Pressure Controller Type PCV 39-02
Type 39-02 steam pressure reducing valve controls the output pressure and keep it in the special set point automatically. The valve is normally open and as the output pressure increases, it gets gradually closed.  The correct direction of steam in the valve is indicated by one arrow on its body. Output pressure is conducted to actuator via condensate chamber and connection pipe then entered to diaphragm surface. This force is transferred to the plug by rod and changed the distance between seat and plug .in this way pressure is fixed at adjustment set point. This device has an accordion piece which balances input and output pressure and also it works as a mechanical seal. This valve is self-operated and it does not need any extra force.
