I. Product Overview
The flanged fire protection signal gate valve features a flanged connection structure, with both ends of the valve body bolted to pipeline flanges. The gate and seat adopt a flat sealing design, paired with water-resistant sealing materials to ensure reliable sealing performance. The valve is equipped with an integrated signal feedback device that converts the valve’s open/closed status into an electrical signal, enabling real-time transmission to the fire control center.
This valve is specifically designed for fire protection piping systems. It is suitable for clean water media, with operating temperatures ≤80℃ and working pressure ≤1.6 MPa. Typical applications include automatic sprinkler systems, fire hydrant systems, and fire water cannon systems. It is primarily used to control the flow of fire protection media and, through signal feedback, ensures system monitoring and operational reliability.
II. Product Features
Flanged Connection Provides high connection strength and excellent sealing performance. Capable of withstanding elevated pipeline pressure, it is suitable for large-diameter fire protection systems. Once installed, it offers strong stability and effectively handles pressure fluctuations under fire conditions.
High-Precision Signal Feedback Device Equipped with devices such as limit switches, the valve accurately detects open/closed positions. The electrical signal transmission is stable, ensuring the fire control center receives real-time valve status updates—meeting the requirements of fire system linkage control.
Flat Sealing Structure The gate and seat are precisely machined to form a flat sealing surface. When closed, the valve achieves tight sealing, preventing leakage of fire media and maintaining system pressure stability—fully compliant with fire protection sealing standards.
Durable Materials and Corrosion Resistance The valve body is made of ductile iron or cast steel with anti-corrosion treatment, offering strong rust resistance. The gate is made of high-quality steel with high strength and wear resistance, ensuring long service life and reliable performance in demanding standby conditions typical of fire protection systems.
Efficient Flow Capacity When fully open, the gate allows unobstructed flow with minimal resistance. This ensures rapid and sufficient delivery of fire media during emergencies, meeting high-volume water supply demands.
Flexible Operation Supports manual and electric actuation. Manual operation offers smooth opening and closing, while electric actuation enables remote control—suitable for various fire protection scenarios and operational requirements.
III. Main Standards
The valve’s design, performance, and installation comply with the following national and industry standards:
• GB 5135.6-2019 – Automatic Sprinkler System – Part 6: General Valves • GB/T 12234-2019 – Steel Gate Valves for Petroleum, Petrochemical, and Related Industries • Relevant fire protection product certification standards
Specific technical parameters, performance indicators, and installation guidelines should be based on the product’s factory-issued technical documentation.
