Pressure Regulating Valves
Pressure Regulating Valves are valves which automatically regulate the pressure within an instrument or pipeline system. There are two main types of pressure regulation; back pressure regulation and pressure reducing.
Pressure Reducing valves are fairly self-explanatory, they take a given system pressure form the inlet and reduce said pressure to a pre-determined point. These types of valves are able to deal with a range of inlet flows whilst producing a constant pressure on the outlet.
Back Pressure Regulators deal primarily with upstream pressure regulation. They do this by relieving downstream pressure. This valve type functions in a very similar way to a relief valve but they are generally more responsive and accurate in terms of both venting and reseating.
