PURPOSE: A pressure control valve of a high pressure pipe in a generating station is provided to prevent the abrasion and damage of a piston and a housing and smoothly control vapor pressure. CONSTITUTION: A pressure control valve of a high pressure pipe in a generating station comprises a housing and a piston. The housing is formed by laminating a plurality of disk type metal plates through a brazing process, wherein a metal plate has a maze type through hole(152) and a protrusion(153). A cylindrical supporting element(180) is inserted into the central through hole of the housing. The supporting element has a plurality of vapor passage holes(190) and a piston passage hole.
