Burkert Type 0330 G1/4 Solenoid Valve | 00018410 00018814 00018857 | Media Isolated Valve

The Type 0330 G1/4 series direct-acting solenoid valves by Chengyuan Hydraulic are high-performance pivot-armature valves fully compatible with Burkert standards. This range, featuring part numbers 00018410, 00018814, 00018857, and 00019059, is specifically engineered for demanding applications where sealing reliability is paramount. The core feature is the Media Isolation structure: a flexible diaphragm physically separates the solenoid actuator from the fluid chamber, ensuring that metallic moving parts like the armature never touch the media. This design makes the 0330 exceptionally reliable for neutral fluids as well as aggressive, viscous, or crystallizing media. As a premium interchangeable solution, all Chengyuan units undergo 100% leak and pressure cycle testing to ensure 100% original-place interchangeability.

Key Technical Advantages:

• Physical Media Isolation: The armature system is completely sealed in a dry actuator chamber, isolated from the fluid. This effectively solves jamming issues caused by scaling, corrosion, or chemical attack, drastically extending the valve’s operational life in harsh environments.

• Low-Friction Pivot Design: Unlike traditional reciprocating plungers, the pivot mechanism performs a small arc motion during opening, eliminating sliding seal wear. This “non-contact” actuation ensures high precision even after tens of millions of cycles.

• Versatile Circuit Capability: The 0330 series supports not just simple ON/OFF functions but also mixing, distributing, and universal functions through different internal configurations. For models like 00018857, the 3/2-way structure provides precise pressure distribution for pneumatic systems.

• Integrated Manual Override: Equipped standard with a manual operation knob, allowing for manual intervention without power. This is highly practical for initial system commissioning, maintenance inspections, and emergency resets during power failures.

Application Areas:

• Chemical Processing: Dosing and quantitative control of mildly acidic or alkaline reagents.

• Water Treatment: Automatic sampling and shut-off in laboratory ultrapure water equipment and industrial RO systems.

• Medical/Biochemical Analysis: Cross-contamination-free transport of saline, blood, or chemical reagents.

Expert Maintenance Tips:

• Port Sealing: When installing G 1/4 threads, use high-quality PTFE tape or hydraulic sealant. Ensure no debris enters the valve body, which could damage the precision diaphragm.

• Voltage Verification: For models like 00018410 (24V DC) and 00018814 (230V AC), double-check the coil voltage before installation to avoid coil burnout due to incorrect wiring.

• Preventive Inspection: Despite the isolation design, if handling highly crystallizing media, periodic internal cleaning is recommended to prevent deposits on the back of the diaphragm from affecting actuation sensitivity.
