MAC 6323D-251-PM-221DA Pneumatic Solenoid Valve

Description

The MAC Valves 6323D-251-PM-221DA is a high-performance, 4-way (5/2) double solenoid valve designed for industrial pneumatic applications. Part of the 6300 series, it features a balanced poppet design that ensures high flow capacity and a long operational life. This valve is pilot-operated via two PME-221DA solenoids and is suitable for systems requiring precise and rapid control of air flow. Its sub-base plug-in design allows for easy installation and maintenance.

FAQ

Question?
What is the difference between the main model 6323D-251-PM-221DA and the REPL. UNIT 6323D-000-PM-221DA?

The difference is typically in the manual override option. The '-251' in the main model number indicates a locking recessed manual operator, while the '-000' in the replacement unit number signifies no manual operator. The core valve function remains identical.

Question?
What does the 'balanced poppet' design mean for performance?

The balanced poppet design means that the forces from the air pressure are equalized across the moving part (the poppet). This results in consistent shifting times regardless of pressure fluctuations, requires less energy to actuate, and contributes to a longer service life.

Question?
Can this 24V AC valve be operated with 24V DC?

No. This valve is equipped with AC solenoid coils (PME-221DA) designed for 24V at 50/60 Hz. Applying 24V DC will likely cause the coil to overheat and fail, as AC coils have a lower resistance and rely on impedance for current limiting. A DC-rated coil would be required for DC operation.
