Regulators/Controllers

Transcat offers pressure controllers and regulators for managing pressure, velocity and flow. Our controllers support applications from compressor and process control to damper and fan control. We provide differential controllers to maintain the desired pressure differential between two parts of a process. We also have pneumatic controllers that automatically activate control elements, such as valves, to sustain a set point.

Our selection of leading pressure regulators allows for the management of gas or liquid flow and the maintenance of set pressure. Pressure regulators are process-driven and use a control element to reduce pressure in spite of changes to flow or supply pressure.
