Burkert 00221864 Type 0330 Solenoid Valve | 3/2-Way Pivoted Armature Valve | G 1/4 Brass Body

The 00221864 (Burkert Type 0330 compatible) pivoted armature solenoid valve from Chengyuan Hydraulic is a high-performance control solution engineered for demanding industrial environments. Unlike conventional plunger-type valves, this model utilizes specialized pivoted armature technology, which uses an isolating diaphragm to physically separate the solenoid system from the fluid chamber. This design effectively protects internal electromagnetic components from corrosive media or particulate contamination. Every Type 0330 valve undergoes 100% simulated condition testing before shipping to ensure that sealing integrity and switching frequency precisely match OEM standards, guaranteeing 100% original-place interchangeability.

Key Technical Advantages:

• Media Isolation Technology: The combination of the pivoted armature and diaphragm forms a physical barrier. The fluid only contacts the valve body and diaphragm, preventing ingress into the solenoid tube. This is ideal for acidic/alkaline solutions, laboratory fluids, or contaminated hydraulic oils.

• Exceptional Mechanical Service Life: The pivoted armature design has a short stroke and no sliding friction, leading to significantly lower wear compared to traditional plunger structures. This results in a cyclic life of millions of operations, drastically reducing maintenance costs.

• Integrated Manual Override: The 00221864 comes standard with a manual override knob. During commissioning or power-loss maintenance, technicians can manually actuate the valve for logic validation, facilitating easy field setup.

• Full-Load Simulated Validation: Chengyuan performs 100% simulated load testing on frequency response and vibration resistance. This ensures the valve maintains high reset accuracy even under high cycling rates.

Application Areas:

• Water Treatment: Control for chemical dosing and precision metering systems.

• Laboratory Equipment: Automated fluid path switching in analytical instruments.

• Hydraulic Auxiliary Control: Pilot control for lubrication systems and pneumatic/hydraulic actuators.

• Machine Tool Cooling: Cutting fluid flow control, preventing metal chips from contaminating the solenoid mechanism.

Expert Maintenance Tips:

• Diaphragm Inspection: While FKM is highly durable, we recommend checking the diaphragm integrity every 12-18 months during high-frequency use to prevent potential scoring from sharp impurities in the media.

• Voltage Stability Management: Ensure the 24V DC supply remains within ±10% fluctuation. Excessive voltage transients can overheat the coil and affect the precision of the pivoted armature’s pull-in.

• Mounting Orientation: For optimal service life and to prevent sediment buildup, mounting the solenoid head in a vertical upright position is highly recommended.
