Bayan Fully stainless steel type self-pressure regulating valve consists of valve body, valve seat, valve core parts etc., is a kind of energy saving product without requiring external energy but only relying on the adjusted medium's own pressure change to automatically adjust pressure, widely used in corrosive liquids, gases and steam such media as pressure control devices.
