Pressure reducing valves control the flow of liquid or gas and shut off once a certain pressure level is reached. They are used in various industries for water pressure relief, propane gas, SCUBA diving, and RVs. They can be set for any downstream pressure level and contain a diaphragm, gauges, and a regulating handle. Water pressure reducing valves are used to conserve water and energy. Propane and LP tanks require a pressure reducing valve for a constant flow of force. Divers use dive regulators to regulate airflow from gas cylinders. RVs use pressure reducing valves to prevent damage to pipes and joints from high water pressure.
A pressure reducing valve, often referred to as a pressure regulator, is a device that controls the flow of a liquid or gas and automatically shuts off the flow once a certain pressure level is reached. Pressure reducing valves are used on an assortment of devices across different industries. They are used for water pressure relief, proper operation of propane gas and liquefied petroleum (LP) tanks, effective performance of SCUBA divers’ air tanks, and optimal operation of some recreational vehicles. They are also used in the gas, oil and mining industries.
Pressure reducing valves can generally be set for any required downstream pressure level that is within the valve construction parameters. According to the uniform plumbing code, a hydraulic pressure reducing valve is required on all hydraulic systems that exceed 80 psi (5.62 kg/cm). Although pressure reducing valves vary slightly in design and function, all valves contain a diaphragm, inlet and outlet gauges, and a pressure regulating handle.
For the reduction and conservation of water pressure, a water pressure reducing valve is often implemented. They can be installed in homes, businesses and industrial buildings in order to lower water pressure and decrease the flow of unnecessary amounts of water. The pressure reducing valve operates automatically, regulating the flow of pressure from a facility’s main water supply. This valve is an economical and environmentally friendly way to reduce water and energy consumption and costs.
All propane and LPG tanks must have an air pressure reducing valve. Normally, the pressure levels in propane and LP tanks vary greatly and a pressure reducing valve must be present to ensure a constant flow of force downstream. They are available in a wide variety of shapes and styles to meet individual LPG and propane tank needs.
Divers depend on a supply of breathable air. A pressure reducing valve on a diver’s air tank is called a dive regulator. It delivers oxygen to the diver by regulating the airflow from gas cylinders and ensures that the receiver receives healthy and comfortable breathing airflow.
Recreational vehicles, or RVs, also often employ the use of pressure reducing valves. On campsites, water tanks commonly have very high pressure levels. When hooking up an RV to one of these tanks, excessively high water pressure could cause serious damage to the vehicle’s pipes and joints. A pressure reducing valve, which connects to an everyday hose, ensures the smooth flow of water from the source to the vehicle’s well.
