Description

1/4" Zero Pressure Stainless Solenoid Valve – CS ADS8


CS Fluid Power Direct-Acting Normally Closed Solenoid Valve

The CS Fluid Power ADS8 Series is a compact 1/4" 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 ADS8 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's specification identifies the ADS range for slight acid and alkali-resistant applications.

Valve Function & Operation

Function: 2/2 way normally closed
Operation: Direct acting (zero rated)
Thread: 1/4" BSPP standard
Optional threads: NPT or Rc
Minimum operating pressure: 0 Bar
No minimum pressure differential required
Vacuum rating: Down to 10⁻⁶ Torr
Opening / closing time: 20ms maximum
Mounting: Any position

Orifice, Flow & Pressure

ADS8A
Orifice: 3.0mm
Kv flow factor: 4.3 L/min
Pressure AC: 0 to 10 Bar
Pressure DC: 0 to 7 Bar

ADS8B
Orifice: 4.0mm
Kv flow factor: 9.7 L/min
Pressure AC: 0 to 7 Bar
Pressure DC: 0 to 5 Bar

ADS8C
Orifice: 5.0mm
Kv flow factor: 10.7 L/min
Pressure AC: 0 to 5 Bar
Pressure DC: 0 to 3.5 Bar
Flow figures based on water with 1 Bar pressure drop.
These individual ADS8A, ADS8B and ADS8C pressure ratings are specified in the technical sheet rather than a blanket 0–10 Bar rating for every orifice.
