Description
1/2" Zero Pressure Stainless Solenoid Valve – CS ADS15
CS Fluid Power 316 Stainless Assisted-Lift Solenoid Valve
The CS Fluid Power ADS15 is a high-flow 1/2" assisted-lift (Magnalift) 2/2 way normally closed 316 stainless steel solenoid valve designed for vacuum, zero-pressure and general industrial fluid control applications.
Unlike conventional pilot-operated valves, the assisted-lift design requires no minimum pressure differential, allowing operation from 0 Bar while retaining a large 15mm orifice and high flow capacity.
Suitable for air, water, light oils, vacuum, RO and demineralised water, mildly acidic or alkaline media and compatible fluids and gases, the ADS15 combines a corrosion-resistant 316 stainless steel body, stainless steel internals and a serviceable diaphragm design for reliable continuous-duty operation.
Typical Applications
RO and demineralised water systems
Pure water systems
Process fluid control
Vacuum and low differential pressure systems
Industrial washing equipment
Chemical dosing systems
Compressed air and inert gas systems
OEM machinery and process engineering installations
Laboratory and instrumentation systems

Why Choose the ADS Assisted-Lift Valve?
The ADS15 combines the zero-pressure capability of an assisted-lift valve with the corrosion resistance of a 316 stainless steel body.
Its Magnalift construction allows reliable operation from 0 Bar differential pressure, including vacuum applications, while the 15mm orifice provides a Kv flow factor of 64.4 L/min.
Compared with a conventional pilot-operated solenoid valve, the ADS15 is particularly useful where inlet pressure can fall to zero or the pressure differential across the valve is too low to operate a standard pressure-assisted diaphragm valve.
