Type number: 637.43
The family-owned company RIEGLER & Co. KG in Bad Urach has stood for innovative, high-quality solutions in the field of compressed air and pneumatic components for over 80 years
RIEGLER Precision pressure regulator without mano made of die-cast zinc, for compressed air preparation - Type 637.43
The RIEGLER precision pressure regulator o. Mano, G 3/8, 0.05-7 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 7 bar with a maximum inlet pressure of 16 bar. The permissible medium temperature is between -35 °C and 60 °C. Connection thread G 3/8 - suitable for common industry standards. Suitable for ultra-fine filtered, non-lubricated compressed air (0.01 µm). The flow rate is 5500 l/min. Uniform working pressure for constant process quality.
