RIEGLER Precision pressure regulator, Pneumat. remote controlled, G 1/2
Type number: 637.603
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 made of die-cast zinc, painted black, for compressed air preparation - Type 637.603
The RIEGLER precision pressure regulator, pneum. remote-controlled, G 1/2, 0.05 - 7 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, painted black 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 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 (at P1 = 5 bar, P2 = 3 bar and pressure drop Δp ≤ 0.1 bar). Uniform working pressure for constant process quality.
