PURPOSE: A pressure regulating device for a descaler valve is provided to prevent excessively fast opening and closing of a valve and thus to reduce impacts. CONSTITUTION: A pressure regulating device for a descaler valve comprises a main body(10), a plunger(20) which is movably installed in the main body and opens/closes a flow path between first and second hole(12,14), and a flow rate regulating unit(70) which regulates the amount of working fluid discharged from the main body. The flow rate regulating unit includes a regulating pipe(72) which is installed in the second hole and has an inlet(72a) and an outlet(72b) and a regulating member(74) which is movably installed in the regulating pipe and opens/closes a flow path between the inlet and the outlet. |
