Membrane pressure reducer Top

Characteristics
 
Membrane pressure reducer equipped with stopper with compensated surfaces. This measure ensures stability of outlet pressure regardless of variations in upstream pressure. The calibration system includes a pair of springs that act on an oscillating housing which isolate the stopper and the membrane from the torsions and lateral flexion induced by the working of the spring.
The stopper is made of synthetic material with a low friction coefficient to reduce the formation of lime build-up, which is the main cause of malfunctions. The reducer is also provided with a reduced section mesh filter, which can be inspected in the version with transparent cup. This further increases durability and protects the plumbing circuit from any impurities which may be present in the water supply. The control knob and the graduated scale in the upper part allow easy adjustment of the calibration pressure. Therefore, the reducer can be calibrated to the desired pressure prior to installation and the system, when powered up, will automatically go the set value. The pressure reducers are calibrated at the test bench with an upstream pressure of 8 bar and 3 bar downstream, with 100% testing prior to packaging.
