RIEGLER Precision pressure regulator without internal air consumption made of die-cast zinc - Type 637.73
The RIEGLER precision pressure regulator without internal air consumption, G 1/4, 0.2 - 6 bar reduces the inlet pressure precisely to a constant working pressure and protects downstream consumers from pressure fluctuations. The housing is made of die-cast zinc with NBR seals. The control range extends from 0.2 bar to 6 bar with a maximum inlet pressure of 16 bar. The permissible medium temperature is between -10 °C and 60 °C. Connection thread G 1/4 - suitable for common industry standards. Suitable for ultra-fine filtered (5 µm), oil-free compressed air, neutral gases. The flow rate is 540 l/min. Uniform working pressure for constant process quality.
