00041337 Bürkert Diaphragm Service Kit for Type 0281 DN8

00041337 Bürkert: Restoration Kit for DN8 Pilot Valves

The 00041337 (short code **41337**) is a dedicated Wearing Part Set for small-bore Bürkert solenoid valves, specifically the DN8 (8mm) orifice models of the **Type 0281** series. Small-diameter valves are highly susceptible to performance degradation from particulate matter and mineral deposits. This kit allows for a complete internal overhaul, replacing the diaphragm and springs that manage the valve’s pilot-controlled switching. By using the 00041337 kit, users can extend the life of their DN8 valves by several million cycles, maintaining tight shut-off and rapid response times in laboratory and light industrial applications.

Technical Details

• Orifice Size: DN 8.
• Seal Material: NBR.
• Compatibility: Type 0281 / 0255.
• Included Parts: Main diaphragm, plunger seal, body O-ring, spring.
• Max Temperature: +80°C.

Maintenance & Application Notes

Lifecycle State: Active. Diagnosis: For DN8 valves, a common problem is the valve «stretching» or failing to close against pressure. This is usually due to loss of tension in the stainless steel return spring. This kit includes the correct spring to restore factory-set closing force. Installation Advice: Use a clean, lint-free cloth to wipe the internal cavity before installation. Even a single hair or piece of lint on the seat of a DN8 valve can cause a significant leak. Compatibility: Ideal for compact manifold systems where valves are mounted in groups. Ensuring each valve is serviced with original Bürkert 00041337 kits maintains system-wide reliability and avoids cross-contamination issues.

Cost Efficiency

The 00041337 kit is a cost-effective alternative to purchasing a new valve, especially in systems with multiple DN8 units where bulk servicing can be performed during planned shutdowns.
