How Do HG2 Breakaway Flanges Work?

Hydrant Guard Dual Plate Check Valve HG2 During Normal Operation

HG2 during normal operation:

HG2 dual plate check valve resides between the water main and the hydrant, allowing nearly full flow capacity when the hydrant is needed.

Hydrant Guard HG2 Dual Plate Check Valve Immediately Following a Shear

HG2 immediately following a shear:

When a hydrant is sheared (broken), HG2's breakaway bolts snap and the valve doors spring shut as the hydrant separates from the valve.

HG2 following a hydrant shear:

As the hydrant fully separates from the valve, HG2 effectively shuts off flow from the water main. Only a witness stream remains to alert first responders.

Why is the Hydrant Guard HG2 a cost-effective solution?

Hydrant Guard HG2 stainless steel valves not only save money by keeping water in the ground, they are also cost-effective to install and maintain. Following a shear, HG2 simply needs to be reset by installing new breakaway bolts and rubber gaskets. Learn more about our dual-plate, stainless steel check valve for wet barrel hydrants with a consultation.

What sets our product apart from alternative solutions?

  1. The HG2 is easy to install, requiring only two operators with hand tools in normal conditions.
  2. The HG2 is designed to be reset after a shear, so it can be used again and again.
  3. HG2’s proprietary breakaway bolts prevent damage to the HG2 and to the water main.
  4. By preventing water surges from sheared hydrants, Hydrant Guard can increase the resilience of the water supply system, ensuring that water is available when it is most needed.
  5. In the event of a broken fire hydrant, HG2's witness stream signals a sheared hydrant, which can enhance emergency response times and reduce the risk of further damage.

Finally, we offer a 10-year warranty because we believe in the durability of our product!
