I. Product Overview
The grooved fire protection signal butterfly valve adopts a grooved-end quick connection structure. The valve body connects to the pipeline via grooved couplings, eliminating the need for welding or threading. The stem and disc are coaxially designed and paired with water-resistant soft sealing materials (such as nitrile rubber) to ensure reliable sealing. An integrated signal feedback device converts the valve’s open/closed status into an electrical signal, which is transmitted in real time to the fire control center.
This butterfly valve is specifically designed for fire protection piping systems. It is suitable for clean water media, with operating temperature ≤80℃ and working pressure ≤1.6 MPa. Typical applications include automatic sprinkler systems and fire hydrant systems. The valve controls water flow and provides real-time status feedback to ensure system reliability.
II. Product Features
Grooved Connection Quick installation without welding or threading. Reliable sealing and fast adaptation to emergency fire pipeline installations reduce construction time.
Built-in Signal Feedback Device Equipped with a travel switch that converts the valve’s open/closed status into an electrical signal, enabling real-time monitoring by the fire control center.
Soft Sealing Structure Tightly fitted sealing surfaces ensure zero leakage, maintaining system integrity during standby and operation.
Durable Materials Valve body made of ductile iron with high strength and impact resistance. The disc is corrosion-resistant and suitable for long-term standby conditions in fire systems.
Easy Operation Supports manual or electric actuation. Low operating torque allows quick opening/closing in emergencies, meeting fire response requirements.
Efficient Flow Design Complies with fire protection standards. Low flow resistance and high flow capacity ensure rapid delivery of fire media during fire events.
