The pressure reducing valve will flow up and down with different water pressure.

Grooved Tee Reducing is one kind of grooved tees. It does not require welding and can be used to install a wide variety of pipe types.

Standard galvanized malleable iron nipples are critical components for installing steel and cast iron pipelines. Designed to connect cast iron or steel fittings, they facilitate thread size transitions (e.g., from smaller to larger diameters) while maintaining secure, pressure-tight connections.

The zsfz system is a neutral height extinguishing system. it consists of a wet alarm valve, a delay, a hydraulic alarm bell and other components (such as pressure switches, water flow indicators, nozzles, etc.).

It is mainly composed of box body, hose reel, foam liquid container, negative pressure proportional mixer, foam spray gun, alarm button, guide frame and pipeline assembly, etc. It is a high efficiency low-power foam fired fire extinguishing device.

The jps series fire hose reel is an indoor fixed firefighting facility that consists of valves, input pipelines, reels, hoses and spray guns, etc., and can spray fire extinguishers in the process of rapidly unfolding the hose.

Fire signal gate valve is the valve with the opening and closing signal device of the valve, when the input 24v voltage, the valve is closed to 1/4 of the full opening degree, the closed signal of the valve can be transmitted to the control center

The elbow is characterized by a 45° bend, used in piping systems requiring directional changes. It enables smooth transition between external and internal threads via threaded connections, allowing flexible pipeline configurations for various applications.
