Above Ground Hydrant
1.Anti-freeze technology: Equipped with an automatic drainage device to effectively prevent freezing in winter.
2.Impact-resistant design: Adopts impact-resistant components and spring-closed drainage ports to avoid leakage after contact.
3.Pressure regulation function: Features an automatic pressure regulator to adjust output pressure under different water pressure conditions.
Product Introduction
The SSFT, SSFW, SSF, SST impact-resistant pressure-regulating outdoor fire hydrants and SSP outdoor above-ground foam fire hydrants are upgraded from Above Ground Hydrant. They integrate pressure regulation, impact resistance, and automatic drainage functions, suitable for general fire-fighting scenarios.

Working Principle
1.Anti-freeze Mechanism
The automatic drainage device automatically closes and drains based on the internal water pressure of the hydrant head.
When the water pressure is not lower than 0.1MPa during operation, the drain valve closes; it drains automatically after shutdown to prevent water accumulation and freezing cracks.
2.Impact Protection
The fire hydrant is equipped with impact-resistant components. In case of collision, the valve head automatically closes under pipeline pressure to prevent water leakage and maintain the normal operation of other hydrants.
When components break, the bolt body and valve body are not interconnected, allowing for quick repair.
3.Pressure Regulation Function
The hydrant structure supports stepwise opening; adjusting the opening height controls the water flow pattern to achieve precise pressure regulation.
When the inlet water pressure is 1.2MPa, the outlet pressure can be adjusted between 0.3MPa and 1.0MPa.
