Gas pressure regulator

Gas pressure regulator Product detail

Overview

RBE1821 gas pressure regulating valve is an energy-saving pressure regulating valve that does not need external energy, but only relies on the pressure change of the medium to be adjusted to achieve automatic adjustment and stable pressure difference. It can be applied to gas pressure regulating systems, mainly for gas or gas pressure regulation.
