Burkert Type 0330 Solenoid Valve | 00136348 00125348 00125329 | 24VDC 230VAC

The Type 0330 Series solenoid valves by Chengyuan Hydraulic are industrial-grade, high-performance direct-acting pivot-armature valves fully compatible with Burkert standards. This range, featuring part numbers such as 00136348, 00125348, 00125329, and 00065438, is designed for neutral and aggressive gaseous and liquid media. The primary advantage of the 0330 series is its Media Isolation design, where the solenoid actuator is completely separated from the fluid chamber by a flexible diaphragm. This makes the valve exceptionally reliable for contaminated or corrosive fluids. Available in 24VDC and 230VAC, all valves undergo 100% leak and functional testing to ensure 100% original-place interchangeability for original Burkert units.

Technical Specifications :

• Core Series: Type 0330

Key Technical Advantages:

• Unique Pivot-Armature Drive: Unlike traditional plunger-style valves, the 0330 uses a pivot-armature mechanism that eliminates sliding friction during switching. This non-contact drive drastically reduces mechanical wear, providing a service life of tens of millions of cycles.

• Superior Media Isolation: The high-performance diaphragm keeps the solenoid armature in a dry, isolated environment. This prevents fluid-borne particles from jamming the armature and allows the valve to handle mildly corrosive or crystallizing media.

• Integrated Manual Override: Comes standard with a lockable manual override. During power outages or commissioning, technicians can manually switch the valve to ensure system safety or temporary operation.

• Low Heat Rise Coil Design: Utilizing premium enameled copper wire and specialized injection molding, the coil offers high heat dissipation efficiency. Even at $100\%$ duty cycles, the temperature rise remains within safe limits, preventing insulation aging.

Application Areas:

• Fluid Analysis Systems: Handling corrosive reagents or sampling fluids in analytical instruments.

• Water Treatment: Chemical dosing systems and pure water piping control.

• Industrial Cleaning: Injection of detergents and control of high-temperature spray cycles.

Expert Maintenance Tips:

• Mounting Orientation: While the 0330 can be mounted in any position, it is best to install it with the solenoid vertical. This prevents sediment from accumulating around the diaphragm, extending its operational life.

• Electrical Connection: Always use the dedicated cable plug (Type 2508) with a sealing gasket. Ensure the locking screw is tightened to maintain the IP65 rating against water and dust.

• Seal Compatibility: For aggressive media, verify the seal material according to the part number. FKM is ideal for oils and most chemicals, while EPDM is suitable for hot water and acids but must never be used with mineral oils.
