February From Experience: Bonus Content

As discussed in the February issue of From Experience, proper pipeline and component sizing are essential for effective pressure control in a liquid system.

To develop a well-balanced piping system, pressure control devices should be integrated into the design. A few typical devices with actuated control valves include:

• Back Pressure Regulators/Pressure Regulators. Back pressure regulators maintain constant inlet pressure regardless of fluctuations in the outlet pressure and pressure regulator maintains constant outlet pressure regardless of fluctuations in the inlet pressure. They are essential in applications where precise pressure control is required.  These devices are readily obtainable for non-hygienic applications.  They can also be procured for hygienic fluids from a few specialty vendors with adjustable springs or with actuated control from most major hygienic valve manufacturers.
• Manual Globe Valves. Globe valves can be used to precisely control flow. Angle style globe valves can be used in sanitary applications such as clean compressed air and purified water. Manual globe valves have the advantage of flexibility and can be used during startup to balance the flow in the system.
• Orifices. Orifice plates are a simple and reliable way to reduce pressure and flow in a system.  They have no moving parts and can be used in tight spaces since they can be easily fit within a sanitary clamp assembly.  Because there are no movable parts, flow through the plate cannot be directly adjusted.
