Double Interlock Pre-action Valve DI-P1-10K-150

Mô tả sản phẩm

The DI-P1-10K-150 Double Interlock Pre-action Valve is a high-performance fire protection control valve specifically designed for double interlock pre-action sprinkler systems. Manufactured by PARATECH Korea under the Fesco brand, the valve provides the highest level of protection against unintended water discharge while ensuring rapid system activation during genuine fire emergencies.

Operating on the double interlock principle, the valve requires two independent events before allowing water to enter the sprinkler piping: activation of the fire detection system and operation of one or more sprinkler heads. This dual-confirmation mechanism significantly reduces the risk of accidental water release caused by false alarms, mechanical damage, or isolated system faults, making it the preferred solution for facilities housing valuable equipment or water-sensitive assets.

Available in DN150, the DI-P1-10K-150 is suitable for demanding fire protection applications where maximum system reliability and operational security are required. Its robust construction ensures dependable long-term performance while maintaining efficient hydraulic characteristics under emergency operating conditions.

The valve is particularly well suited for protecting data centers, telecommunications facilities, control rooms, museums, archives, clean rooms, electrical substations, semiconductor manufacturing plants, and other mission-critical environments, where both fire protection and protection against unnecessary water damage are equally important.

Designed and manufactured by PARATECH Korea, the valve incorporates proven engineering, durable materials, and a compact design that simplifies installation and maintenance while minimizing installation space requirements within fire protection valve stations.

Since 1973, when Korea's fire protection industry was still in its infancy, Paradise Industry, now known as PARATECH, has operated under the corporate philosophy of "contributing to society by protecting lives and property from fire." The company obtained more than 20 national certifications for its fire protection products, including automatic fire sprinklers, and became the first manufacturer to supply these products in Korea. PARATECH subsequently expanded its research and development to manufacture a comprehensive range of fire protection valves and equipment.

Today, PARATECH is the largest fire protection equipment manufacturer in Korea, producing specialized fire protection valves, automatic sprinkler heads, flexible sprinkler hose assemblies, fire department connections, UL/FM approved fire protection valves, and numerous other specialized fire protection products.

Fire protection products marketed under the Fesco brand are exported worldwide, including Europe, the United States, Japan, and many countries throughout Asia, particularly Southeast Asia.

PGTECH supplies premium fire protection products manufactured by PARATECH, Korea's largest fire protection equipment manufacturer. With nearly five decades of experience, the Fesco brand has established an outstanding reputation for quality, innovation, and reliability.
