CA-Fire Flange-Type Wet Alarm Valves

1. Product Name & Positioning

Full Name: CA-Fire ZSFZ-80~300-1.6 Series CCC & ISO Certified Flange-Type Wet Alarm Valves (Stainless Steel/Ductile Cast Iron, Water-Medium Dedicated)

Abbreviation: CA-Fire ZSFZ Flange Wet Alarm Valves

Core Positioning: A dedicated control-and-alarm integrated valve for wet fire systems-distinct from our previous pre-action valves (dual-activation, dry-normal) and deluge valves (open-system focused). It operates in a "permanently water-filled" state, activating instantly when fire triggers downstream sprinklers, while synchronously sending alarm signals. With wide-caliber compatibility (DN80~DN300) and dual-material options, it balances rapid fire response, large-system,and low customization thresholds-ideal for large-scale commercial, residential, and public buildings requiring reliable wet-system control globally.

2. Core Product Advantages (Distinct from Pre-Action/Deluge Valves)

Wet-System Optimized Instant Activation: Unlike pre-action valves (needing dual triggers) or dry deluge valves (requiring pipeline filling time), this wet alarm valve keeps the entire system water-filled under normal conditions. When a sprinkler head activates (e.g., glass bulb ruptures), water flows immediately-response time ≤2 seconds, 50% faster than pre-action valves, critical for high-traffic areas like shopping malls where every second reduces fire spread risk.

Wide Flange Caliber for Large-Scale Systems: Covers DN80~DN300 nominal diameters, far broader than pre-action valves (DN100~DN200) or small-caliber water dividers. The flange connection is optimized for large main pipelines (e.g., DN300 for shopping mall main water supplies), supporting fire protection for 10,000+㎡ spaces with a single valve-avoiding the need for multiple small-caliber valves and complex pipeline parallel connections.

Low Customization Threshold (MOQ Only 100 Units): Unlike most fire valves (customization MOQ ≥2000 units), this flange wet alarm valve allows logo/packaging/graphic customization with just 100 units. This is a huge advantage for medium-sized projects (e.g., residential community renovations) that don't require mass orders but need brand alignment-lowering the barrier for small-to-medium clients.

Dual-Material Adaptability for Diverse Environments: Offers stainless steel (for humid areas like swimming pool adjacent corridors) and ductile cast iron (for general dry spaces like office buildings) options. The ductile cast iron version uses a high-pressure casting process (tensile strength ≥420MPa) for impact resistance, while the stainless steel version resists water-induced rust-covering more scenarios than single-material flange deluge valves.

Integrated Alarm & Simplified Maintenance: Built-in water flow sensors and alarm ports that automatically trigger sound/light alarms when water flows (no external alarm devices needed, unlike water dividers). The wet-system structure has no complex dual-control components (vs. pre-action valves), so annual maintenance only requires 1–2 pressure checks-cutting maintenance workload by 60% compared to pre-action valves.

4. Applicable Scenarios (Leveraging Wet-System Advantages)

Large Commercial Buildings: Shopping malls, department stores, and office towers-permanently water-filled state ensures instant response to fires in high-traffic areas, while wide caliber (e.g., DN300) supports multi-floor water supply without pressure loss.

Residential Communities: High-rise apartments and villa complexes-flange connection fits residential fire main pipelines, and low maintenance (annual pressure checks only) reduces property management workload.

Public Service Venues: Hospitals, schools, and elderly care centers-fast activation (≤2s) protects vulnerable groups (patients, children) by minimizing fire spread time, and the closed system avoids accidental water leakage (unlike open deluge valves).

Medium-Scale Industrial Workshops: Light manufacturing workshops (e.g., textile, electronics assembly) with no low-temperature freezing risk-ductile cast iron version withstands minor mechanical vibration, while stainless steel resists humidity-induced rust.

5. Frequently Asked Questions (FAQ) – Focused on Wet & Flange Features

What's the key difference between this wet alarm valve and your pre-action valve?The core lies in system state and activation: this valve stays water-filled (instant activation for general scenarios), while pre-action valves stay dry (needs dual triggers for water-sensitive areas like data centers). If your project has no risk of false activation or freezing, this wet valve is more cost-effective and faster-responding.

Why is the customization MOQ only 100 units (much lower than other valves)?The flange connection and wet-system structure have high mold compatibility-customizing logos or packaging doesn't require major mold modifications (unlike pre-action valves' dual-control components). This allows us to support small-to-medium batches for community renovations or regional projects.

Does the flange connection require professional installation?Yes, but it's simpler than you think: we provide flange alignment marks and torque parameters (e.g., DN100 flange requires 50N·m torque). A team of 2 workers can install 1 unit in 30–40 minutes-no specialized calibration (unlike deluge valves that need system pressure testing).

How often does this wet alarm valve need maintenance?Only 1–2 times a year: check if the valve body has water leakage, and verify the alarm function by simulating small water flow. This is far less frequent than pre-action valves (4–5 times a year for detector calibration) because it has no complex dual-activation components.
