Rückschlagventile
Ventile
Check valves allow compressed air or hydraulic fluid to pass in one direction only and close automatically on pressure drop or flow reversal. The range covers pneumatic and hydraulic versions with G ports from M 5 to G 2", with the hydraulic check valve RUCK HD series handling pressures up to PN 350 and selectable cracking pressures from 0.3 to 8.0 bar. Stainless steel versions (RUCK 12 SS, ES) are available for aggressive media. Pneumatic quick exhaust valves of the SV series with replaceable FKM membranes complete the programme.
