Pressure regulators monitor and control pressure in various systems, such as water, gas, and fuel. They use valves to maintain safe pressure levels and prevent damage to equipment and people. Many types of machinery and systems use regulators, including natural gas, propane, welding, cutting, water towers, and municipal water systems. Regulators also prevent excessive pressure buildup that could cause system failure and endanger lives.
Pressure regulators are devices designed to monitor and control the amount of pressure flowing through a system of some kind. There are regulators designed to control water pressure, as well as gas and fuel pressure. The typical pressure regulator can be set to alert operators of problems when high pressure conditions exceed predetermined safe levels.
As part of the process used to regulate pressure, a pressure regulator monitors the pressure level found within a system, as well as the escape rate of liquid or gas from the system. When needed, a valve will open and close to keep the pressure level within an acceptable range. For example, a pressure regulator on an irrigation system would use the recommended drip requirements associated with the system as a standard for correct pressure levels. In the event that the water pressure drops below a certain level, the valve will close and allow the pressure to reach an acceptable range. When the pressure returns to a reasonable level, the valve will open and allow the irrigation process to proceed.
Many types of machinery and systems make use of pressure regulators. Natural gas and propane systems require the presence of a pressure regulating valve in order to maintain safety levels and direct the gas flow. Welding and cutting machinery that uses water as part of a cooling system also uses a regulator to control the rate of release during use. Water towers and municipal water systems use regulators to maintain an adequate level of water pressure for use by community residents.
The pressure regulator is sometimes employed as a means of controlling the flow of water from an elevated source. To ensure that water flow does not exceed the capacity of equipment located at a lower elevation, a simple screw-in pressure regulator is often attached to the receiving end of the water hose. The regulator compensates for the increase in pressure and slows the water flow to a rate that the equipment can process without damaging system components.
Using a pressure regulator does more than just prevent damage to equipment and make sure homes have enough water pressure in their plumbing systems to function properly. Regulators also prevent excessive pressure from building up that could cause system failure and endanger the lives of people in the immediate area of the breach. This is especially true with regulators used to control the flow of flammable substances such as gasoline or propane gas.
