Description

The pressure regulator Elephant PRA is a normally open regulating body, the principle of which is based on balancing the force of elastic deformation of the spring and the force created by the pressure difference of the working medium in the diaphragm chambers of the drive. Elephant PRA pressure regulators are designed to automatically maintain a given pressure of the working medium after the regulator (before the object of regulation) by changing the flow rate.
