00041340 Bürkert: High-Precision Repair for DN10 Solenoids
The 00041340 (or **41340**) is the official Service Kit for Bürkert **Type 0281** and **Type 0255** solenoid valves featuring a DN10 (10mm) orifice. In high-cycle industrial automation, the diaphragm is the most stressed component, undergoing constant mechanical flexing. The 00041340 kit ensures that the valve’s integrity is maintained by replacing the entire wearing assembly. This is critical for preventing unscheduled downtime in processes that rely on precise fluid control, such as dosing systems, pneumatic controls, and chemical bypass lines using neutral media.
Key Technical Characteristics
- Valve Size: DN 10.
- Diaphragm Material: NBR (Nitrile).
- Fluid Compatibility: Compressed air, vacuum, neutral liquids.
- Set Includes: Diaphragm, core spring, pilot seal, body O-ring.
- Temperature Limit: Max +80°C.
Engineer’s Troubleshooting Guide
Lifecycle State: Active Spare. Diagnosis: If the valve fails to open but the coil is energized (and you hear a «click»), the pilot port in the diaphragm may be clogged or the main diaphragm may be stuck to the seat. The 00041340 kit provides a fresh start for the valve internals. Installation Advice: Lubricate the O-ring slightly with a compatible silicone grease to ensure a perfect seal during bonnet reassembly. Do not over-torque the screws, as this can pinch the diaphragm perimeter. Compatibility: Often found in **Siemens**-controlled hydraulic panels where Bürkert valves serve as the primary actuators. Using genuine Bürkert kits ensures the response times remain consistent with the PLC’s programmed timing.

Pro-Tip
Always check the plunger for wear marks. The 00041340 kit includes a new pilot seal that sits at the tip of the plunger, which is the most common leak point for valves that won’t shut off completely.
