1.2 Product Description
The Welker
AP-3
Adjustable Probe is designed for use in systems where it is desirable to insert and retract the probe while the
pipeline remains pressurized. When used with a pipeline isolation valve, the AP-3 can be safely inserted and retracted manually
without interfering or venting pressure when operating pressure is reduced to the appropriate level.
Welker may custom design the AP-3 to suit the particular application and specifications of each customer.
