PROBLEM TO BE SOLVED: To provide a two-part liquid reaction type piping member made of a resin excellent in chemical resistance, heat resistance, solvent resistance, oil resistance and low elution performance of an organic material and a metal ion, and also an impact resistance strength. SOLUTION: A flow path 8 is formed inside a valve body 1 made of a hollow cylindrical two-part liquid reaction type resin (DCPD), a roughly disc-shaped top flange 6 extruded to the outer periphery is provided on the top, a bearing recessed part 7 keeping the lower end part of a system 4 inserted is provided on the bottom, a seat ring 2 made of a hollow cylindrical FKM is formed on the inner circumference surface of the valve body 1 so as to be integrated with the valve body 1, the upper end part of the system 4 made of SUS 403 turnably supported by the valve body 1 and the seat ring 2 is placed so as to be protruded from the center of the top flange 6 provided on the top of the valve body 1, the lower end part is inserted into the bearing recessed part 7 to be fixed to the warm wheel 9 of the gear box of a valve operation device, and a valve element 5 made of a circular PVDF is placed in the center inside the valve body 1 to be attached to the system 4 passed through the center of the valve element 5 so as not to be turnable.
