mottrykkregulators

Mottrykkregulator, also known as backpressure regulator, is a type of pressure regulator used in fluid systems. Its primary function is to maintain a specific backpressure downstream of the regulator. Unlike a standard pressure regulator that controls the pressure of the fluid leaving the regulator, a mottrykkregulator controls the pressure *before* it reaches a certain point in the system. This is achieved by sensing the downstream pressure and adjusting a valve to restrict flow when that pressure exceeds a set point.

These devices are commonly employed in applications where a consistent backpressure is crucial for the proper operation of other components or processes. For example, in pneumatic systems, a mottrykkregulator might be used to ensure that a certain minimum pressure is always present in a line, preventing issues like pneumatic actuators from losing their holding force. In hydraulic systems, they can be used to maintain pressure on pumps or to ensure proper operation of hydraulic motors.

The mechanism typically involves a diaphragm or piston that is acted upon by the downstream fluid pressure. This force is opposed by a spring or a set of weights. When the downstream pressure increases, it pushes against the diaphragm/piston, which in turn moves a valve to restrict the flow and increase the upstream pressure. Conversely, if the downstream pressure drops, the spring/weights force the valve open, allowing more fluid to pass and maintain the set backpressure. Mottrykkregulatorer are available in various designs and materials to suit different fluid types, operating temperatures, and pressure ranges.
