Pressure Regulating Valve

Air pressure regulator is applicable for pressure regulation in airtight rooms and also in the ventilation ducts to maintain required pressure difference between the zones. They should be used everywhere where it is necessary to provide linear characteristic of pressure regulation, despite of air volume. According to the application the device can maintain constant or variable pressure difference depending on the sequence of control. Thanks to using a static pressure sensor the regulator can work in environments with low and medium contamination levels including aggressive chemicals. In case of lack to determine how much chemically aggressive the gases are, it is recommended to test the device prior to the installation.

 Differential pressure regulator is intended for pressure control in airtight rooms and ventilation ducts, at the same time maintaining the set pressure difference between two zones. They should be used when the linear characteristic of pressure control is required, regardless of the volumetric flow value. Depending on the assumed functionality, the device maintains constant or variable pressure difference, depending on the precalibration made by the manufacturer and on the controlling method. Thanks to the static pressure sensor, the regulator may operate in the environment with a low and an average pollution and corrosiveness level (Corrosive Environments Classification according to ISO 12944 max. class C3). If a corrosiveness degree of the environment is not known for sure, it is recommended to pre-check the resistance of the device material and of the transducer itself to expected adverse operating conditions.
