Pressure regulator - Wikipedia

Water Pressure Reducing Valves How They Pressure reduction valve Installed directly pressure reduction valve the water meter in homes, commercial buildings, and manufacturing plants, a water pressure reducing valve automatically reduces the pressure from the water supply main to a lower, more sensible pressure.

There are two types of water pressure reducing valves-- direct acting and pilot operated-- which use globe or angle style bodies.

Direct acting valves are pressure reduction valve more popular water pressure reducing valves, consisting of globe-type bodies with a spring-loaded, heat-resistant diaphragm connected to the outlet of the valve that acts upon a spring. This spring holds a pre-set tension on the valve seat installed with a pressure equalizing mechanism for precise water pressure control.

Water Pressure Reducing Valves

Every Drop Counts High water pressures waste water. Many municipalities today not only charge homeowners and businesses high rates for water consumption, but also for the disposal of wastewater. Most home cooking models are built to maintain a low and high pressure setting. These settings are usually between 7 and 15 PSI.

Almost all home cooking units will employ a very simple single-stage pressure regulator. Older models will simply use a small weight on top of an opening that will jiggle to allow excess pressure to escape.

Newer models usually incorporate a spring-loaded valve that lifts and allows pressure to escape as pressure in the vessel rises. Some pressure cookers will have a quick release setting on the pressure regulator valve that will, essentially, lower pressure reduction valve spring tension to allow the pressure to escape at a quick, but still safe rate.

Commercial kitchens also use pressure cookers, in some case using oil based pressure cookers to quickly deep fry fast food. In this case, and pressure reduction valve the case of cooking at home, pressurized vessels can be used to cook food much more rapidly than it would take to cook large amounts of food without pressure.

Pressure vessels of this sort can also be used to sterilize small batches of equipment and in home canning operations. Water pressure reduction[ edit ] Often, water enters water-using appliances at fluctuating pressure reduction valve, especially in remote locations, and industrial settings.

A single-stage regulator is sufficient in accuracy due to the high error tolerance pressure reduction valve most such appliances. Also used in applications where the water supply reservoir pressure reduction valve significantly higher in elevation to the end of the line.

Oxy-fuel welding and cutting[ edit ] Oxy-fuel welding and cutting processes require gases at specific pressures, and regulators will generally be used to reduce the high pressures of storage cylinders to those usable for cutting and welding.

Pressure regulator

Oxy-gas regulators usually have two stages: The first stage of the regulator releases the gas at a constant rate from the cylinder despite the pressure in the cylinder pressure reduction valve less as the gas is released. The second stage of the regulator controls the pressure reduction from the intermediate pressure to low pressure.

It is constant flow.

The valve assembly has two pressure pressure reduction valve, one indicating cylinder pressure, the other indicating hose pressure. Because pressures in propane tanks can fluctuate significantly, regulators must be present to deliver a steady flow pressure to downstream appliances.

Propane regulators differ in size and shape, delivery pressure and adjustability, but are uniform in their purpose to deliver a constant outlet pressure for downstream requirements. As is the case in all regulators, outlet pressure is lower than inlet pressure.

Gas powered vehicles[ edit ] No matter what type of motor internal combustion engine or fuel cell electric powertrain a specific pressure regulator will be necessary to bring the stored gas CNGHydrogen pressure from, or bar or 70, 50, 35 and 20 Pressure reduction valve to operating pressure in addressing all pressure reduction valve and operational requirements.

Recreational vehicles[ edit ] For recreational vehicles with plumbing, a pressure regulator is a necessity. When pressure reduction valve, a source of water may have an enormous pressure level, particularly if it comes from a tank that is at a much higher elevation than the campground.

Water pressure is dependent on how far the water must fall.

Without a pressure regulator, the intense pressure encountered at some campgrounds in mountainous areas may be enough to burst the camper's water pipes or unseat the plumbing pressure reduction valve, causing flooding. Pressure regulators for this purpose are typically sold as small screw-on accessories that fit inline with the hoses used pressure reduction valve connect an RV to the water supply, which are almost always screw-thread-compatible with the common garden hose.

Breathable air supply[ edit ] Main article: The tank may contain pressures well in excess of 2, PSI, which could cause a fatal barotrauma injury to a person breathing it directly.
