Made of high - quality materials, the valve's body, bonnet, stem, and disc assembly are mainly copper alloy (with NBR and SS304 gaskets in the disc assembly), and the handle wheel is aluminum alloy. This material combination ensures the valve has good corrosion resistance, high - pressure resistance, and durability, enabling it to maintain stable performance in long - term use and emergency fire - fighting situations. With a working pressure of PN16, it meets the water supply pressure requirements of most indoor fire protection systems, and the oblique structure design facilitates installation and operation in limited space inside fire hydrant boxes.
