REQUEST TECHNICAL DATA & QUOTE

Main Feature: Dual Integrated Micro-switches for Remote Monitoring

Specializing in High-Performance Fire Safety Valves Since 1995.

Product Overview

The Signal Fire Protection Butterfly Valve is a critical component for automatic sprinkler systems and firefighting pipelines. Engineered for precise control and safety monitoring, it features a specialized gearbox equipped with internal micro-switches that transmit the valve's open or closed status to the fire control panel. The wafer-type design allows for a compact, lightweight installation between standard pipe flanges. Manufactured from high-tensile ductile iron and coated with anti-corrosive fire-red epoxy, this valve ensures long-term operational reliability in high-pressure fire main systems.

Key Technical Advantages

Integrated Signal Monitoring: Built-in signal switch box provides real-time feedback to prevent accidental system shutdown.
Compact Wafer Design: Space-saving installation between flanges, significantly reducing weight and installation time.
Ductile Iron Body: High strength-to-weight ratio and superior impact resistance compared to standard cast iron.
Smooth Operation: High-precision worm gear actuator ensures low torque and smooth manual operation.
Corrosion Protection: Internal and external epoxy powder coating (FBE) protects against scale and corrosion.
