Burkert 0355 2/2-Way Proportional Solenoid Valve | Media Isolated | 00126056 00183202

The 0355 Series proportional solenoid valves from Chengyuan Hydraulic are high-precision fluid control units fully compatible with Burkert standards. The standout feature of Type 0355 is its Media Isolation design—utilizing a high-quality diaphragm to completely separate the solenoid actuator from the flow path. This prevents chemical corrosion of the motor parts and protects the medium from contamination. For core part numbers like 00126056, 00183202, and 00061104, we use advanced corrosion-resistant plastics or stainless steel bodies. Every valve undergoes 100% simulated responsiveness testing to ensure excellent linearity and low hysteresis, guaranteeing 100% original-place interchangeability.

Key Technical Advantages:

• Media Isolation Technology: The physical separation between the solenoid and the fluid allows the valve to handle aggressive chemicals and high-purity fluids without risk of actuator corrosion or medium contamination.

• Superior Linear Response: Through optimized plunger strokes and spring rate matching, the valve delivers highly linear flow control across 10% to 100% of the duty cycle, eliminating control oscillations.

• Low Hysteresis Performance: Utilizing low-friction coatings and precision-ground guide bushings, the valve achieves consistent opening/closing resistance, with response times within milliseconds.

• Versatile Integration: Available in threaded or sub-base mounting versions, it interfaces seamlessly with existing controllers (such as Type 8605), simplifying system integration and part replacement.

Application Areas:

• Medical & Bio-tech: Precision dosing in analytical instruments and lab automation.

• Chemical Processing: Micro-dosing of corrosive gases and liquids.

• Semiconductor Industry: Ultrapure water control and cleaning processes.

• Environmental Monitoring: Flow stabilization in gas sampling systems.

Expert Maintenance Tips:

• Controller Selection: For optimal performance, always use a dedicated PWM amplifier. Applying a constant voltage will result in loss of control or solenoid overheating.

• Mounting Orientation: To prevent sediment buildup, install the valve with the solenoid pointing vertically upwards. This maximizes the long-term reliability of the diaphragm seal.

• System Filtration: Despite the isolated design, installing a filter ($<20\mu m$) upstream is highly recommended to protect the diaphragm from mechanical abrasion caused by particles.
