Z41H Flanged Cast Steel Gate Valve
Compact structure, reasonable design, good valve rigidity, smooth passage, and low flow resistance coefficient. The sealing surface is made of stainless steel and hard alloy, ensuring a long service life. It uses flexible graphite packing for reliable sealing and easy, flexible operation. The drive modes include manual, electric, pneumatic, hydraulic, and gear transmission. The structural forms are divided into elastic wedge single gate and double gate types. Widely used in pipelines for oil products, water, steam, and corrosive substances as a starting device for connection or disconnection.
The flow switch is mainly used to monitor the flow rate of water in online or insertion-type installations within water medium pipelines. When the water flow exceeds or falls below a certain set point, it triggers an output alarm signal to be sent to the unit, allowing the system to take corresponding action based on the received signal. This helps to avoid or reduce the risk of the main unit 'dry burning'.

LWBT-16P Stainless Steel Flow Meter
Ultrasonic flow meters are mainly used for measuring the flow of liquid media in fire protection pipelines and other applications. The principle of ultrasonic flow meters is to use ultrasonic transducers to send and receive ultrasonic waves, measuring the time difference of propagation in the downstream and upstream media to determine the flow velocity. In the downstream direction, the ultrasonic wave speed increases, while in the upstream direction, the speed decreases. Therefore, the same propagation distance will have different propagation times. Based on this time, the flow velocity is obtained, and then the flow rate is calculated from the flow velocity.
The fire pressure switch is a pressure control device that can issue an alarm or control signal when the measured pressure reaches the rated value. Fire pressure switches are generally used to start the sprinkler pump, monitor the working status of the alarm valve, and detect changes in the pressure within the pipeline.

The flow indicator is divided into two main categories: impeller type and float type (also known as direct flow impeller sight glass, impeller sight glass, direct float sight glass, float sight glass liquid flow observer, flow indicator, collector, single-tube direct flow sight glass). It is a direct sight glass and is an essential accessory for observing the flow conditions of materials within a pipeline.
The ZSFC dry alarm valve is the water supply control valve for dry sprinkler systems. The pipeline system is usually filled with pressurized gas (also used to monitor the sealing of the pipeline) to keep the valve closed. When the sprinkler head opens, the gas pressure in the pipeline drops rapidly, the valve opens, water enters the pipeline system, and is discharged from the opened sprinkler head, performing the fire extinguishing function.
The straight stream nozzle produced by our company emits a columnar water flow, with a long range, large flow rate, and strong impact force, used for extinguishing general solid material fires and for auxiliary cooling during firefighting. It can generally be divided into ordinary straight stream nozzles and switch straight stream nozzles.
The fire water cannon is the latest design by our company, incorporating advanced domestic technology. This fire water cannon is fully functional, has a long range, a simple and novel structure, stable and reliable performance, and flexible operation, making maintenance convenient. The cannon body can rotate horizontally and tilt vertically, and it can achieve reliable positioning and locking to facilitate the evacuation of firefighters from the scene, ensuring their personal safety.
ZSFG Rain Soaked Alarm Valve - Lever Type
The ZSFG rain forest alarm valve has a lever structure and features a reset prevention function, complying with the GB5135.5-2003 standard. The rain forest alarm valve is widely used in various open systems (open sprinklers on the system side piping), such as rain forest systems, water curtain systems, and mist systems. The opening of the ZSFM rain shower alarm valve is achieved by releasing the pressure in the diaphragm chamber of the rain shower valve, using the pressure from the water supply side to open the valve disc. The pressure release in the diaphragm chamber can be done in various ways, including electrical guidance, wet guide, and dry guide.
T-ZSTZ- 15-68°C upright, quick response fire sprinkler head
The upright sprinkler head is installed vertically on the water supply branch, with a spray pattern resembling a parabolic shape, directing 80-100% of the total water volume downward. At the same time, the upright sprinkler head also sprays a portion towards the ceiling, making it suitable for installation in areas with a lot of moving objects where collisions are likely, such as warehouses. It can also be concealed in the ceiling space of a room to protect flammable materials on the ceiling. (In areas without a ceiling, when the water supply branch is arranged under a beam, an upright type should be used. For areas prone to collisions, a sprinkler head with a protective cover or a ceiling-mounted type should be used.)
Quick Response Sprinkler Head (All Copper)
The advantages of quick response nozzles are that their thermal sensitivity is significantly higher than that of standard response nozzles, allowing them to activate early in a fire situation. They can start spraying water during the initial small fire stage, reducing the difficulty of extinguishing the fire. This enables rapid firefighting with less water usage, which can minimize casualties and economic losses caused by fire damage and water contamination. Therefore, it is proposed to use them in atrium corridors and public entertainment venues with high foot traffic, as well as in places where elderly people, children, and individuals with disabilities gather.
