Excess Pressure Control Valve PCV 10-35

Working Range : Excess Pressure Control Valve is a useful device to fix pressure on an adjusted set point. Its adjustable pressure range is 1~10bar and 14.5 ~ 145Psi. It is produced from DN125 to DN150 size, based on DIN standard. Its nominal pressure is PN16 to PN25 and in 6″ size based on ANSI. Working class is 150# or 300# and maximum working temperature is 350℃ or 662°F.  10-35 valve is usable for liquid, non-flammable gases and steam lines.

Function: Type 10-35 steam pressure reducing valve controls the output pressure to keep line pressure in the special set point automatically. This valve is normally closed and as the input pressure increases, it gets gradually open. This valve is suitable for all fluids apart from inflammable gases. The correct direction of steam in the valve is indicated by one arrow on its body. Position of plug and free area between the plug and seat controls the rate of steam flow. This function is performed by a pilot valve and adjustment it on special set point. The extra Pressure behind pilot valve is transferred to the actuator of master valve through triode ways, then rod transmits this pressure to plug. As a result of this action, the position of seat and plug is changed and pressure stays in the adjusted set point. This valve is a self-control valve and it does not need any extra force. Its repair and adjustment is so easy, has high accuracy and PTFE sealing.

Installation : Excess Pressure Control Valve is only suitable for installation in horizontal pipelines. The flow direction in the valve must be corresponding with the arrow on its body and the actuator of device must be installed upside-down. Before pipeline designation, pay attention to accordant of valve size to the flow rate and adjustment rang. In the steam line, to protect the valve from pipeline condensation, the pipeline must be installed with a moderate slope to flow direction or also you can use a steam trap in the pipeline. After installation you have to be sure that valve is not pressed in pipeline. To adjust pressure on the set point, use a regulating nut. 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 suitable strainer in its input side.
