1. Quick on/off. Just rotate the wrench 4-5 turns to fully close and open.

2. Pressure regulating function. The internal pressure-reducing device is segmented and activated due to the pressure of fire water, with a portion of the water passing through the device upwards first. After a period, another segment is activated, thereby achieving pressure reduction.

3. Collision Protection. In the event of a collision, this fire hydrant's valve can automatically close and immediately stop the water flow, without affecting the normal operation of other hydrants on the same pipeline. It also allows for pressure repair of damaged parts, making it the preferred product for municipal engineering projects.
