Elektrische Flansch-Absperrklappe (DN40-DN1200) - Mehrdreh-Antrieb | DELCO

✅High-Torque Multi-Turn Actuation
The valve is driven by a Z-series multi-turn electric actuator coupled with a worm gearbox. This system multiplies torque output to handle the immense pressure loads of large valves (bis DN1200) while controlling closing speed to prevent damaging water hammer effects.
✅Stable Double Flanged Body (U-Type)
Im Gegensatz zu Waferventilen, the double-flanged design bolts directly to pipe flanges on both sides. This provides superior mechanical stability, isolates the valve from pipeline stress, and allows for dead-end service (installing at the end of a line) without downstream flange support.
✅Notfall-Handlauf
Reliability is paramount. The actuator assembly includes a side-mounted Manual Handwheel. Im Falle eines Stromausfalls, operators can manually rotate the handwheel to open or close the valve, ensuring continuous system safety and control.
✅Vielseitige Dichtungsoptionen
To match various media, the valve can be fitted with resilient seats (EPDM/NBR) for zero-leakage water/air service, or hard seals (Metal/PTFE) for higher temperature or abrasive conditions. The concentric or eccentric disc design ensures low operating torque.
✅Global Standard Compatibility
The flanges are drilled to match international standards including GB, ANSI 150, DIN PN10/16, und JIS 10K. The robust body materials (Gußeisen, WCB, SS304) make it suitable for HVAC, Kommunale Wasserwerke, and industrial power plants.
