ABSTRACT:
Disclosed herein is a valve for regulation of a fluid consisting essentially of fluid passage members attached integrally to both sides of a valve casing by means of frictional pressure-welding. The above casing includes a back pressure chamber and the spacing between the fluid passage members and the back chamber define stay chambers inside the joint sections at both sides which mitigate shock and damaging effects by hydraulic inertia to the valve, and prolong its life.
