Description

Single-Latched Pre-Action Valve

The Single-Latched Pre-Action Valve is a dry pre-action valve system that operates based on detector activation, with no water normally present in the system piping. The pipes are filled with pressurized air or nitrogen gas. The valve opens only when the fire detectors are triggered, allowing water to enter the piping and flow through the sprinkler heads.

This system is preferred in areas at risk of freezing and environments where accidental water discharge is undesirable. Its single-trigger requirement provides a fast yet controlled response.

Key Features:

  • Activated by detector signal

  • Pipes remain dry (no water present)

  • Prevents water flow in case of accidental sprinkler activation

  • UL/FM approved components

  • Compatible with manual and automatic test valves

  • Easy maintenance and commissioning

Applications:

  • Freeze-prone areas

  • High-ceiling warehouses

  • Archive rooms

  • Industrial facilities

  • Sensitive environments with electronic equipment
