VK157 Standard Dry Vertical Sidewall Fire Sprinkler

The VK157 Standard Dry Vertical Sidewall Fire Sprinkler provides targeted fire suppression in commercial, industrial, and residential areas where freezing temperatures threaten wet piping networks. It installs directly onto walls or structural columns in dry pipe, pre-action, and wet pipe assemblies, maintaining a dry barrel to prevent ice blockages in unheated spaces, exterior walls, or cold storage facilities. Upon exposure to heat, the unit activates automatically to suppress fires while isolating water until discharge is required.

This assembly complies with NFPA 13 installation standards for fire sprinkler system design and meets strict life safety code requirements. It carries UL Listings and FM Approvals to verify performance compliance for commercial and industrial applications.

Key Features & Construction

• Corrosion-Resistant Build: Fabricated using brass and stainless steel components to withstand moisture-prone environments and chemical exposure.
• Dry System Compatibility: Engineered for dry pipe and pre-action systems, keeping water out of freeze-susceptible areas until thermal activation.
• Vertical Sidewall Orientation: Mounts directly to walls or structural columns to deliver precise spray patterns in confined, tight, or architectural layouts.
• Standard Response Technology: Utilizes a standard response heat-activation mechanism for reliable operation.
• System Versatility: Fully compatible across dry pipe, wet pipe, and pre-action fire protection assemblies.
