Pressure Regulating Valve Working Principle

A pressure regulator is a valve that automatically cuts off the flow of a liquid or gas at a certain pressure. Regulators are used to allow high-pressure fluid supply lines or tanks to be reduced to safe and/or usable pressures for various applications.

Gas pressure regulators are used to regulate the gas pressure and are not appropriate for measuring flow rates. Flowmeters, rotometers or mass flow controllers should be used to accurately regulate gas flow rates.
