Safety Start Valves ASS
SMC safety start valves of the ASS series are soft-start valves that allow the pressure build-up of a pneumatic system to rise slowly at switch-on. Only after a threshold is reached is the full cross-section released, which avoids a sudden start of cylinders.
The series comprises more than 40 items with port sizes from G1/8 to G1, supplemented by matching mounting brackets. Soft-start functions form part of safety-oriented pneumatic concepts according to ISO 4414.
