American MAC 811C-PP-221BA-152 solenoid valve for Universal insertion machine.
ITEM Parameter Details
Valve Structure: 5/2 Two-position 5-way single-electro-operated pilot-operated solenoid valve
Working Medium: Compressed air, inert gas
Pressure Range: Internal pilot: 25~150 PSI (approx. 1.7~10.3 bar); External pilot: Vacuum ~ 150 PSI
Coil Specifications: 24VAC (50/60Hz), Power: 5.4W (60Hz) / 6.7W (50Hz)
Response Characteristics: MAC high-frequency design, millisecond-level response, suitable for high-speed operation in plug-in machines
Interface/Installation: Standard NAMUR mounting interface, suitable for valve island installation in plug-in machines
Service Life: MAC balanced valve core design, anti-contamination, long service life, suitable for high-frequency industrial conditions
Voltage Matching: The PPE-221BAAA coil is for 24VAC only. Ensure the equipment is powered by AC 24V to avoid burning out the coil if connected to DC 24V.
Pressure Requirements: The air supply pressure of the insertion machine system must be stable at 0.5~0.6MPa (approximately 70~90PSI) to meet the 25~150PSI operating range, while also filtering moisture and impurities from the air supply to extend valve life.
Troubleshooting: Stuck/Not Operating: Check the air supply pressure, coil power supply, and whether the valve core is stuck (MAC valves have high requirements for air cleanliness; impurities can easily cause valve core jamming).
Coil Not Engaging: Use a multimeter to measure the coil resistance to determine if it is burnt out; simultaneously confirm that the 24VAC output on the equipment side is normal.
Versatility: This valve is a universal accessory for Universal Insertion Machines and can also be used in other automated equipment that requires high-frequency pneumatic control. Models in the same series, such as 811C-PM-221BA-152, can be replaced according to differences in pilot operation.
High-frequency performance: The balanced valve core structure ensures unaffected operation by air source pressure fluctuations, allowing it to withstand the high-frequency cyclic operation of the insertion machine.
Anti-contamination design: The valve core’s special sealing structure provides enhanced resistance to impurities and moisture in compressed air, reducing on-site malfunctions.
Long lifespan: Industrial-grade design enables millions of trouble-free cycles under continuous operation of the insertion machine.
