Self restrained dismantling joint stroke 50mm type steel PF
DN50-1200
The self restrained dismantling joint Type PF for wafer type valves (without flanges) allow the installation or removal of an equipment between two fixed flanges of a pipeline.
The large stroke sliding system reachs a 50 mm displacement to permit installing and removing the equipment.
For this type of self restrained dismantling joint the locking system to the pipeline is made by the tie bars and the gland.
Range
The self restrained dismantling joint Type PF exists in a range from DN40 to 1200, PFA10 or PFA16.
