Pressure Regulators

Pressure regulators monitor and control the pressure of gas and liquid passing through a system by opening and closing valves in order to match the flow of the fluid to the demand for it. Regulators are used to allow high-pressure fluid lines to be reduced to safe and usable pressures; a build-up of pressure could cause the line or tank to burst, which would be very dangerous for nearby personnel.

Industry Information

Pressure Regulators

Regulators have valves that open and close to allow the right rate of flow and pressure and, like pressure sensors or level transmitters, are often equipped with alarms to alert operators when the pressure exceeds predetermined safety levels. They are usually built from high grades of stainless steel or brass with an attached gauge and plastic or metal nut that can be turned to manually close the valve. Pressure regulators are widely used across many industries. In agriculture, a pressure regulator in an irrigation system will intermittently close a valve until there is enough pressure to effectively water the field. Regulators are used to reduce the high pressure buildup of gases in storage cylinders such as air in scuba diving tanks as well as in propane and oxygen tanks used for welding. Pressure regulators are frequently used with water; they control the flow of water from an elevated source to a lower outlet and also facilitate the proper function of plumbing systems. The water systems used deep in mining operations use pressure regulators to reduce pressure and prevent bursting.

The specific size, style and application of a regulator can vary. However, there are some similarities that virtually all of these devices contain. The majority of pressure regulators have three components: a restricting element such as a valve, a loading element that applies the needed force to the restricting element, like a spring, and the measuring element, which determines when the restricting element should close. Single-stage pressure regulators consist of a diaphragm and a poppet valve. As pressure in the upper chamber of the device is increased, the diaphragm rises, which causes the poppet to reduce flow. This decreases the pressure again. Two-stage pressure regulators work similarly to two single-stage regulators in series. The first state reduces the pressure to an intermediate level, and the second stage reduces it further, down to the desired pressure. The two-stage regulator offers the advantage of a consistent pressure flow until the tank being released is nearly empty. Because the gas or liquid is regulated in two steps, the pressure has a greater delivery accuracy and is used in laboratories and precision welding. Single-stage regulators are more common and less expensive.
