Viking VK510 K25.2 ESFR Pendent Sprinkler

The Viking VK510 K25.2 ESFR Pendent Sprinkler installs directly onto ceiling-mounted wet fire sprinkler systems to protect high-piled storage warehouses and manufacturing facilities. Its early suppression fast response technology detects fires immediately, deploying a high-volume water discharge that suppresses high-challenge fires before flames can spread across tall storage racks.

This sprinkler complies strictly with NFPA 13 ESFR standards, satisfying code requirements for industrial storage occupancies that demand rapid thermal activation and heavy-duty water delivery.

Key Features & Construction

• High K-Factor: Delivers a K-Factor of 25.2 (363 metric) to discharge high water volumes quickly over fire-prone zones.
• ESFR Technology: Provides rapid thermal response and early suppression to minimize heat buildup and limit flame escalation.
• Pendent Orientation: Mounts in a downward position from ceiling piping to distribute targeted water coverage directly onto stored assets.
• Corrosion-Resistant Build: Constructed with robust, corrosion-resistant metals to withstand harsh industrial environments and reduce long-term maintenance needs.
• Integrated Protective Guard: Shields internal mechanical components from accidental physical impacts without altering the spray pattern.
• InstaSeal® Compatibility: Supports optional Torque-Assist caps on select models to simplify installation workflows and improve seal integrity.

Technical Specifications & Compliance

Select models are compatible with revolutionary InstaSeal® technology through the addition of Torque-Assist caps. This feature simplifies installation and enhances sealing performance. Please verify the InstaSeal® compatibility for your specific project requirements.

Contractors must verify all local Authority Having Jurisdiction (AHJ) requirements and cross-reference system hydraulic calculations before installation.
