TDW STOPPLE® Plugging Machines serve as temporary block valves installed anywhere in a piping system. They are used to isolate a section of line for repairs or additions without interruption of service. The STOPPLE Plugging Machine consists of three major sections: a hydraulic cylinder or jackscrew, a plugging head housing, and a plugging head. Operation of the hydraulic STOPPLE Plugging Machine is easy due to the location of the control valve, which is positioned at the lower end of the hydraulic cylinder. The hydraulically operated control bar has a direct reading scale visible to the operator, enabling him to know the plugging head position at all times. The TDW STOPPLE Plugging Machine is available for pipe sizes 4" (DN 100mm) and larger. Its maximum operating temperature is 180°F (82°C). |
