RIEGLER Precision pressure regulator without mano made of die-cast zinc, for compressed air preparation - Type 637.51
The RIEGLER precision pressure regulator o. Mano, G 1/2, 0.05-3 bar, high flow rate 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 0.05 bar to 3 bar with a maximum inlet pressure of 16 bar. The permissible medium temperature is between -35 °C and 60 °C. Connection thread G 1/2 - suitable for common industry standards. Suitable for ultra-fine filtered, non-lubricated compressed air (0.01 µm). The flow rate is 3000 l/min. Uniform working pressure for constant process quality.
