Fire Wafer Butterfly Valve

The fire wafer butterfly valve is a dedicated safety shut-off and control valve specially manufactured for building fire protection water supply systems. Designed and tested in accordance with international fire safety standards, this wafer-type butterfly valve serves as a key isolation and control component for fire sprinkler systems, fire hydrant pipelines and building fire water mains. With compact wafer structure, reliable zero-leak sealing and long-term standby stability, it has become the most widely adopted valve in modern fire protection engineering for commercial buildings, industrial plants and municipal fire pipe networks.

The valve features a slim, lightweight wafer body structure that is clamped between two pipe flanges using through bolts. It requires no welding or additional flange connections, greatly simplifying on-site installation, shortening construction cycles and reducing overall project costs. Its ultra-thin profile allows flexible installation in narrow pipe shafts, ceiling concealed pipelines and compact equipment rooms where traditional flanged valves cannot be arranged. The optimized structural design also reduces pipeline load and vibration impact, improving the overall stability of fire water piping systems.

Built for long-term standby fire service conditions, this fire-rated butterfly valve adopts high-performance elastic soft sealing. The premium EPDM rubber seat delivers excellent aging resistance, water resistance and compression recovery performance, ensuring bubble-tight zero leakage even after years of static standby. The precision-machined ductile iron butterfly disc fits uniformly with the valve seat, maintaining stable sealing performance under rated PN10 and PN16 working pressure. The streamlined disc minimizes fluid resistance and pressure loss, guaranteeing rapid and sufficient water flow output in sudden fire emergencies.

Available in multiple operation types including manual lever, worm gear, electric and pneumatic actuation, the fire wafer butterfly valve adapts to different project design requirements. Manual types are commonly used for conventional on-site inspection and manual cut-off control, while electric and pneumatic versions support automatic linkage and remote management. Optional signal switch devices can feed back valve opening and closing status to the fire control system in real time, helping operators monitor pipeline availability and avoid hidden risks caused by improperly closed or open valves.

In terms of material durability and fire safety performance, the valve body is made of high-strength ductile iron with uniform red epoxy anti-corrosion coating, which complies with standard fire valve appearance and anti-rust requirements. The stainless steel valve stem provides outstanding wear resistance and oxidation resistance, ensuring flexible operation after long-term standby. Every unit undergoes strict shell pressure testing and sealing inspection to meet fire protection codes, ISO9001 and CE certification standards. Complete specifications from DN40 to DN1200 cover all common fire pipeline caliber requirements.

With professional fire-rated design, stable sealing, space-saving installation and diverse control methods, the fire wafer butterfly valve is universally applicable in high-rise buildings, shopping malls, hospitals, warehouses, industrial workshops and underground parking lots. As an essential safety component of fire water supply systems, it effectively ensures the reliability, stability and emergency response capability of building fire protection piping, providing critical safety guarantees for fire prevention and emergency rescue.
