Spark DN50 Fire-Specific Flanged Non-Rising Stem Resilient Seated Gate Valve

Spark DN50 Fire Non-Rising Stem Gate Valve Launches | A New Zero-Leakage Control Option for Compact Fire Pipeline Networks

Fire protection equipment brand Spark has released the DN50 fire-specific flanged non-rising stem resilient seated gate valve, featuring "non-rising stem space-saving + zero-leakage sealing" as core advantages—it has become a preferred control device for compact fire pipeline network scenarios.

This gate valve adopts a DN50 nominal diameter and standard flange connection, adapting to the installation needs of mainstream fire pipeline networks; made of QT450 ductile iron with anti-corrosion coating, it has a rated working pressure of 1.6MPa, stably bearing the pressure load of fire systems. Its core highlight is the non-rising stem handwheel design, which can save about 30% of installation space, perfectly adapting to fire scenarios with compact pipeline layouts such as building mezzanines and pipe shafts; the resilient rubber seat structure achieves zero leakage during fire pipeline on-off operations, solving the fire water loss problem of traditional gate valves.

The product supports operation in a -10℃~60℃ temperature range, has passed CE and ISO dual international certifications, and complies with fire equipment safety specifications; its red appearance meets fire facility identification standards, facilitating quick identification and operation & maintenance management. Currently, this gate valve is officially available on Spark’s self-built website, supporting bulk purchasing and customization inquiries for fire-specific non-rising stem specifications (DN50-DN150).
