Pressure Control Valve PCV 10-23

 :Working Range : Self – Operated pressure control valve is a useful device to fix pressure on an adjusted set point. Its adjustable pressure range is 0.1…28 bar and 3~400Psi. Its size varies from DN15 to DN100 or 1/2″ to 4″. Its nominal pressure is PN16 to PN40 and working class is 150/300. Its maximum temperature is 350°c or 662° F. This device is made based on DIN or ANSI standards. 10-23 valve is usable for liquid, non-flammable gases and steam lines.

  Function : Type 10-23 steam pressure reducing valve controls the output pressure and keep it on the special set point automatically. This valve is normally open and when output pressure increase, it gets gradually closed. This valve is proper for all fluids apart from inflammable gases. The correct direction of steam in the valve is indicated by one arrow on its body. Output pressure is conducted to actuator via control line (via condensation chamber and connection tube, if fluid is  steam) then inter to the diaphragm and this force is transferred to the plug by the rod and changed the distance between seat and plug, in this way pressure is fixed on the adjustable set point. This device has two accordion pieces. One of them balances input and output pressure differences and other one works as a mechanical seal. This valve is self-operated and does not need any extra forces.

 Installation : This valve is only suitable for installation in horizontal pipelines. The flow direction in the valve must be corresponded wit the arrow on its body and the actuator of device must be installed upside-down. Before pipeline designation, pay attention to the input and output size and distance of valve from consumer. To protect the valve from pipeline condensation, the pipeline must be installed with a moderate slope to the flow direction or you can use a steam trap. After installation, you have to be sure that valve is not pressed in pipeline. According to the decreasing pressure in the output of valve, it is recommended to choose bigger diameter for output side of valve. To adjust pressure on the set point, use pressure reducing nut. To protect diaphragm from steam and extra temperature, a condensation chamber is used. Before startup, this chamber must be fulfilled with water. If valve is heavy or it is pressed in the line, you can use a supportive stand to avoid vibration. To prevent unwanted pieces entrance to the valve, use a proper strainer in its input side.
