RIEGLER Standard" pressure regulator made of die-cast zinc, painted silver, for compressed air preparation - Type 637.40 B
The RIEGLER "Standard" pressure regulator, incl. pressure gauge, BG 3, G 3/4, 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, painted silver with NBR seals. The control range extends from 0.2 bar to 6 bar with a maximum inlet pressure of 25 bar. The permissible medium temperature is between -10 °C and 60 °C. Connection thread G 3/4 - suitable for common industry standards. The flow rate is 5000 l/min (at P1 = 8 bar, P2 = 6 bar and pressure drop Δp = 1 bar). Uniform working pressure for constant process quality.
