Description
1/8" Zero Pressure Stainless Solenoid Valve – CS ADS6
CS Fluid Power Direct-Acting Normally Closed Solenoid Valve
The CS Fluid Power ADS6 Series is a compact 1/8" direct-acting 2/2 way normally closed solenoid valve manufactured from forged 316 stainless steel for vacuum, zero-pressure and general industrial fluid control applications.
Unlike conventional pilot-operated valves, the direct-acting design requires no minimum pressure differential, allowing reliable operation from 0 Bar and vacuum while providing a choice of 3mm, 4mm or 5mm orifices.
Suitable for air, water, light oils, vacuum and compatible fluids and gases, the ADS6 combines a corrosion-resistant 316 stainless steel body, stainless steel internals and a wide choice of sealing materials for reliable continuous-duty operation. The manufacturer specifies the stainless construction for slight acid and alkali-resistant applications.
