2" Zero Pressure Brass Solenoid Valve – CS AD50

CS Fluid Power Assisted-Lift Normally Closed Solenoid Valve

The CS Fluid Power AD50 is an ultra-high-flow 2" assisted-lift (Magnalift) 2/2 way normally closed brass 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 very large 50mm orifice and exceptional flow capacity.

Suitable for air, water, light oils, vacuum and compatible fluids and gases, the AD50 combines a forged brass body, stainless steel internals and a serviceable diaphragm design for reliable continuous-duty operation in large-flow industrial systems.

Typical Applications

High-flow compressed air systems

Water transfer and fluid handling

Vacuum and venting systems

Gravity-fed and low-pressure systems

Light oil and fuel systems

Industrial gas control

Process engineering and plant services

Bulk fluid transfer systems

OEM machinery and test installations

Industrial utility services

Why Choose the AD Assisted-Lift Valve?

The AD50 combines the zero-pressure capability of an assisted-lift valve with the extremely high flow capacity required by larger 2" industrial pipework.

Its Magnalift construction allows reliable operation from 0 Bar differential pressure, including vacuum applications, while the very large 50mm orifice provides a Kv flow factor of 686.4 L/min.

This makes the AD50 particularly suitable for vacuum, gravity-fed, bulk fluid transfer, low-pressure and variable-pressure systems where a conventional pilot-operated solenoid valve may not operate reliably.
