The 3A Series Air Control Valve 3 Way pneumatic control fluid directional valve is a fluid directional valve suitable for air as the working medium.
The product has low starting air pressure, with single-head control type featuring spring reset and dual-head control type with position memory function.
The inner hole is processed with special technology, resulting in low friction resistance, no need for oil lubrication, stable lifecycle, and long service life.
The structure is lightweight and easy to install.
Ouleikai (OLK) manufacturers provides customized valve body services, allowing for different surface treatments of the valve.
The 3A series air control valves 3 way and flow control valves are widely used in packaging automation equipment, robot control, compressed air systems, and other fields.

FAQs:
Can the 3A series be field changed to NO or NC?
Self-replacement is generally not recommended because the structural differences in NO/NC relate to trim, spring orientation, etc.
Recommendations:Clear NO or NC selection when placing order
If the model needs to be changed, the valve body can be replaced or the whole valve can be replaced to ensure reliability
Does 3A series pneumatic valve NO/NC mean the same as solenoid valve NO/NC?
Consistent in meaning:NO=normally open /NC=normally closed
However, the pneumatic control valve operates by air pressure signal, and the solenoid valve operates by solenoid force of coil. The two principles are different.
Does the Series 3A NO/NC support CE certification?
OLK Available in:CE (EMC+LVD) certification
What is the difference between NO and NC of 3A series?
NC (normally closed): the valve is closed when there is no air, and it can only be opened after being driven by signal/air pressure.
NO (normally open): the valve keeps open naturally when not breathing, and closes after receiving the signal.
