Valves for industrial applicationsIn order to prevent the uncontrolled rise in pressure in pressure vessels or pressurized pipelines, a safety valve is inserted. The safety valve is designed so that it opens at a given maximum pressure, thereby relieving the line or the container. Safety valves find their use in almost all areas of the pressure vessel and pipeline construction. In cryogenics as a spring-loaded safety valve for example.

A relieving regulator releases excess pressure through a relief valve, a hole in the middle of the diaphragm. When air pressure exceeds the acceptable limit of a system, the relieving regulator opens a vent to allow the air to escape. A hissing sound usually indicates the release of air. There is no need to add an extra relief valve to the flow system since the relieving regulator performs this function on its own.

A non-relieving regulator restricts airflow once it exceeds the setpoint. There’s no vent path in a non-relieving regulator so the gas stays in the system. These regulators require extra care because they can become dangerous if excess pressure builds up without being released. In a closed system, it is important to have a relief valve downstream. Alternatively, an open system design should be implemented downstream of the regulator to prevent the build-up of excessive pressure.

Non-relieving regulators are most beneficial when dealing with hazardous or expensive gases. By trapping these gases for safe or controlled release, operators ensure the safety and efficiency of the entire facility.
