Description

Product Overview

The Flanged Wet Alarm Valve ZSFZ150 is a key control component in automatic sprinkler systems, designed to manage water flow and activate alarms. Suitable for large-flow wet sprinkler systems with DN150 pipelines, it provides rapid response once sprinkler heads activate, converting hydraulic signals into audible and electrical alarms for integrated fire protection.

Key Features

1. Large-Diameter, High-Flow Design

Specially designed for large commercial buildings, industrial facilities, and storage centers, supporting greater water flow to improve initial fire suppression performance.

2. Reliable Wet Alarm Mechanism

Once a sprinkler activates, the change in water flow triggers the valve group instantly, activating the water motor gong and linked pressure switch alarm system.

3. Integrated Water Motor Gong & Pressure Monitoring

Comes with a water motor gong, retard chamber, and pressure gauges for real-time monitoring and clear audible alarms.

4. Pressure-Resistant & Corrosion-Resistant Construction

Manufactured with high-strength cast steel or ductile iron and coated with anti-corrosion finish, ensuring long-term stability in humid or harsh environments.

5. Easy Installation & Maintenance

Flanged connections allow quick installation; compact valve design simplifies commissioning, testing, and maintenance.
