When it comes to selecting pressure regulators, there is a seemingly overwhelming number of choices available on the market. But the fact is, each different type of pressure regulator has a different functionality, and therefore a different purpose in each individual application. Here at Boiswood we aim to help educate all our customers towards learning more about the different types available and how you can select the best regulator for your needs.
Types of Pressure Regulators
- Pressure Reducing – a single stage pressure regulator, designed to take a higher inlet pressure (P1) and reduce to a lower controlled outlet pressure (P2).
- Back Pressure – a back pressure regulator (or “overflow” regulator), designed to maintain a constant inlet pressure (P1), offering end users a controlled and stable line pressure.
- Cylinder Pressure – a dual stage pressure regulator, designed to take a higher inlet pressure (P1) and reduce to a lower controlled outlet pressure (P2). These are often installed on gas cylinders/bottles to provide a higher level of control accuracy as the cylinder depletes.
- Vaporising – either electrically heated or steam heated pressure regulators, designed with either pressure reducing (single stage), back pressure or dual stage mechanical operation. Vaporising regulators are used to heat the media as it passes through the wetted flow path, often situated upstream prior to sampling systems or analysers.
- Speciality Regulators – regulators utilising any of the above-mentioned principles, except designed for different applications including miniature/compact versions for small space claims, dome-loaded for pneumatic pilot air operation, high pressure design for up 10,000 PSIG control, high flow design for up to 3.00 Cv, high temperature for up to +537°C, crossover manifolds for automatic changeover of cylinder bottles and more.
