Title: Spark Handwheel-Operated Fire Butterfly Valve Launches | A Precise Control Valve for High-Flow Fire Scenarios

Fire protection brand Spark has released the handwheel-operated fire butterfly valve, featuring "precise adjustment + high pressure resistance" as core advantages to become a main control component for fire networks in large buildings and industrial plants.

This butterfly valve adopts a grooved connection design, adapting to high-flow fire pipeline layouts. Made of cast iron with anti-corrosion coating and equipped with a rubber-sealed valve plate, it has a rated working pressure of 1.6MPa, stably bearing pressure demands of high-load fire water systems. Its handwheel operation design supports 0°-90° precise adjustment—enabling quick full opening/closing and on-demand flow control, solving the pain point of "insufficient adjustment precision" in traditional valves, and adapting to path management in complex fire scenarios.

The product supports operation in a -10℃~60℃ wide temperature range, is CE and ISO certified, and meets international fire equipment safety standards. As the control core of high-flow pipelines, it balances operational flexibility and structural durability, greatly improving the operational controllability of fire networks. The butterfly valve is now available on Spark’s self-built site, with bulk purchasing and customization inquiries for different nominal diameter specifications supported.
