UL/FM Fire Fighting Equipment
UL FM Fire Alarm Check Valve is a critical supervisory device installed on a fire sprinkler system. It's not one single object, but rather a system component with a specific purpose and certification.
UL FM Fire Water Flow Detector
It is not a direct fire detection device, but a dedicated device for real-time monitoring of the water level status of fire water sources (such as fire water tanks, water tanks, and Wells). Its core mission is to ensure that the fire water supply system has sufficient water available for use in the event of a fire.
UL Flanged Resilient Seated OS&Y Gate Valve
Fire gate valves are indispensable control devices in fire water supply systems. Their main function is to fully open or fully close the water flow rather than regulate the flow rate.
UL Grooved Resilient Seated OS&Y Gate Valve
Grooved Resilient Seated OS&Y Gate Valve combines the installation efficiency of a grooved connection with the operational safety and reliability of an OS&Y design.
UL Flanged End Resilient Seated NRS Gate Valve
It is a type of gate valve that is connected to the pipeline through a flange, and its valve stem only rotates during opening and closing without axial lifting.
UL Grooved End Resilient Seated NRS Gate Valve
Grooved Resilient Seated NRS Gate Valve is a cost-effective and space-saving shut-off valve designed for fast installation. Its combination of grooved ends and a non-rising stem makes it a practical choice for many commercial and industrial applications.
The gate valves are specially designed gate valves for fire protection pipeline systems, and their core function is to reliably connect or cut off water flow.
The Wall Type Indicator Post (Models MH-1510FA/MH-1510A) is a UL/FM-approved wall-mounted fire hydrant system, designed for reliable water supply in commercial, industrial, and urban public spaces—supporting fire truck and hose connection for efficient fire suppression.
Groove Butterfly Valve with Supervisor
Grooved Butterfly Valve with Supervisor is an intelligent, critical component in modern fire protection systems. It combines the quick-installation benefits of a grooved valve with the life-saving function of continuous position monitoring.
Wafer Butterfly Valve with Supervisory Switch
This product is a critical component in modern fire protection systems, combining the flow control of a butterfly valve with the monitoring capability of an electrical switch to provide real-time status feedback.
Grooved End Swing Check Valve is a self-acting valve designed to prevent reverse flow (backflow) in a pipeline, while featuring grooved ends for rapid installation and maintenance.
Swing Check Valve is a self-actuating valve designed to allow fluid to flow in only one direction, automatically preventing reverse flow (backflow) in a pipeline.
