The calibration of PT 100 sensors in bottom outlet valves, which has to be performed in the course of re-validating process equipment, can be a problem in many cases. The valve has to be removed from the reactor and has to be taken to the workshop where it has to be disassembled in order to remove the PT 100 from inside the valve stem.
The stocked Pfaudler valve series AMA/APA-BT provides an easy removal of the PT 100. The PT 100 can be removed from the side. Without any additional tools due to the smart design of the connection between the pneumatic elements or the hand wheel and the valve stem. The valve does not need not be removed from the reactor or disassembled for this purpose.
All components have been designed to avoid the need of additional adjustment work after the reinstallation of the PT 100. And the valve is still absolutely tight of course.
lt was especially important to the Pfaudler developers to keep the space required for removing the PT 100 as small as possible. This is to ensure that the PT 100 can also be easily removed under the normal conditions prevailing under a reactor, namely, where room is extremely limited.
Furthermore a stocked conversion kit comprising of a few parts only is available to retrofit existing valves with the option to remove the PT 100 sensor from the side. Again, the bottom outlet valve does not need to be removed from the reactor for this purpose.
Thus, Pfaudler offers not only the most·compact and light-wejght glassteel bottom outlet valve available on the market, but also one of the most maintenance-friendly ones.
Due to the modular construction, options like diverse temperature and glasstesting probes and air actuator extensions etc. can be realized easily, even subsequently.
