The fire clamp signal butterfly valve is a key valve used in the fire protection system for real-time monitoring and rapid control of water flow. Its core features include:

Structure and Installation: Adopting a mid line clamp design, the valve body has no flange, and is fixed to the pipeline flange through bolt through lugs. The installation is compact and suitable for narrow spaces;

Functional features:

Built in micro switches or sensors provide real-time feedback on valve opening and closing status to the fire control system, ensuring automatic alarm for abnormal conditions;

Bidirectional sealing structure (such as rubber+metal composite seal), pressure resistance range PN10-PN16, suitable for low to medium pressure requirements of fire water systems;

Operation and compatibility: Supports manual+electric/pneumatic dual drive mode, 90 ° quick opening and closing (≤ 10 seconds), and can be manually operated for emergency in case of power failure;

Materials and reliability: The valve body and seals are made of corrosion-resistant materials such as stainless steel and fluororubber to reduce the risk of leakage and extend their service life;

Application scenario: Dedicated to key nodes that require real-time monitoring and rapid response, such as automatic sprinkler systems, fire hydrant pipelines, and fire pump inlets and outlets.

This valve is linked to the fire alarm host through a signal output interface (dry contact or 4-20mA), and complies with fire certification standards such as UL/FM/CCFF.
