Product Details
Product formation
Standard Response Upward/Downward Sprinklers (68°C, K80) are medium-response, general-purpose sprinklers in automatic fire sprinkler systems. Triggered by a temperature-sensitive element, they uniformly spray water at specific angles (upward sprinklers spray downward, downward sprinklers spray upward) to achieve initial fire control and suppression. Designed for conventional commercial and industrial scenarios, they balance response speed and water distribution uniformity. Their universal design (K80 flow rate, 68°C temperature) and adaptability to multiple installation directions make them
one of the most commonly used sprinkler types in fire protection projects, significantly enhancing system cost-effectiveness and fire suppression efficiency.

Product features
Standard Response Upward/Downward Sprinklers (68°C, K80) are medium-response, general-purpose sprinklers in automatic fire sprinkler systems. Their key features are as follows:
- Standard Response Design: Balances "timely fire control" with "stable reliability", making it the optimal choice for conventional commercial and industrial scenarios.
- Precise Action Temperature: 68°C ± 3°C, matching the initial smoldering temperature of common combustibles (e.g., wood, paper, fabric, typically 50–80°C). It triggers water spray beforethe fire escalates, enabling "early intervention".
- Stable Water Distribution: Features a smooth flow characteristic curve, unaffected by pipe network pressure fluctuations (0.1–1.2 MPa), ensuring consistent spray coverage.
- Bidirectional Installation: Adaptable to multiple scenarios—upward sprinklers spray downward, downward sprinklers spray upward—to suit different space needs.
- Low-Maintenance Construction: Valve body made of corrosion-resistant material, paired with long-lasting seals, reducing upkeep costs over its service life.
