CA-Fire ZSFY Series Pre-Action Fire Alarm Valves

1. Product Name & Positioning

Full Name: CA-Fire ZSFY Series CCC & ISO Certified Pre-Action Fire Alarm Valves (Stainless Steel/Ductile Iron, Flange/Groove Connection)

Abbreviation: CA-Fire ZSFY Pre-Action Alarm Valves

Core Positioning: A hybrid-system control valve that combines the advantages of dry and wet fire systems-distinct from our previous deluge valves (wet-system focused) and water dividers (passive distribution). It requires dual activation (fire detection signal + system pressure trigger) to release water, designed specifically for water-sensitive areas (e.g., data centers, archives) where false activation would cause severe damage. With dual-material options and CCC/ISO certifications, it balances anti-misactivation reliability, environmental adaptability, and automatic alarm functionality-ideal for high-value asset protection globally.

2. Core Product Advantages (Distinct from Deluge Valves/Water Dividers)

Dual-Activation Mechanism to Prevent Misspray: Unlike deluge valves (activated by single signal/pressure) that risk false triggering, this pre-action valve needs two conditions: ① Fire detector (smoke/heat) sends an alarm; ② System pressure reaches the trigger threshold (1.6MPa). This "double check" eliminates misactivation from pipeline pressure fluctuations or detector malfunctions-critical for spaces with electronic equipment or cultural relics.

Hybrid Dry-Wet System Compatibility: Under normal conditions, the valve keeps the downstream pipeline dry (like dry-system valves) to avoid freezing or corrosion; when activated, it quickly fills the pipeline with water (like wet-system valves) for fast fire suppression. This solves the "slow response of dry systems" and "freezing risk of wet systems"-a capability unique to pre-action valves.

Dual Material & Connection Flexibility: Offers stainless steel (for corrosion-prone areas like coastal data centers) and ductile iron (for general industrial spaces) options, with flange or groove connections. Unlike our single-material water dividers (cast iron only) or partial-material deluge valves, this dual selection adapts to more complex installation environments without additional adapters.

Integrated Automatic Alarm Function: Built-in pressure switches and alarm ports that trigger sound/light alarms when the valve activates-no need to install independent alarm devices (required for deluge valves). This reduces system complexity and ensures real-time fire notification for on-site personnel.

Short Lead Time for Small-Batch Orders: Delivers 1–10 units in 15 days-far faster than deluge valves (35 days for 1–100 units) or water dividers (35 days for 1–500 units). This is ideal for emergency retrofits of small water-sensitive zones (e.g., a single server room).

4. Applicable Scenarios (Leveraging Pre-Action Advantages)

Water-Sensitive High-Value Zones: Data centers, server rooms, and computer labs-dual activation prevents water damage to expensive electronic equipment from false sprays.

Cultural & Archive Spaces: Libraries, museums, and historical relic storage rooms-dry normal state avoids paper/artifact deterioration, while fast wet activation suppresses fires quickly.

Low-Temperature Environments: Unheated warehouses (northern winter) and cold-chain logistics control rooms-dry pipelines prevent freezing and cracking, unlike wet-system deluge valves.

Small-Batch Emergency Retrofits: Hospital operating rooms, laboratory clean rooms-15-day short lead time meets urgent upgrade needs, and the compact design fits limited installation spaces.

5. Frequently Asked Questions (FAQ) 

How does this valve avoid false activation compared to deluge valves?It requires two triggers: a fire detector signal (e.g., smoke) and system pressure reaching 1.6MPa. Deluge valves activate with just one trigger (e.g., a single broken detector), making false sprays more likely-this dual control is the core anti-misactivation design.

Can it be used in both high and low-temperature environments?Yes. The normal dry pipeline state works in low temperatures (-15℃ to 5℃) without freezing, while stainless steel material resists high-temperature corrosion (up to 80℃) in industrial workshops-wider temperature adaptability than wet-system valves.

Is installation more complex than deluge valves?No. It uses standard flange/groove connections, and we provide a "detection + valve" matching guide. Installation time for 1 unit is ~40 minutes (only 10 minutes longer than deluge valves), with no need for specialized alarm wiring (integrated alarm port).

What happens if the fire detector fails but the valve is triggered by pressure?The valve will not activate-dual activation requires both signals. If one fails, the system remains in standby to avoid misspray. We also recommend pairing it with dual detectors (smoke + heat) for further redundancy.
