Prevent pipe bursts in winter! Freeze prevention valve 'HAT/FP'
Just attach it to the piping! The valve opens and closes automatically in response to temperature! No power source like electricity is needed!
The freeze prevention valve "HAT/FP" automatically opens and closes the valve by sensing the temperature of the water, preventing damage to water pipes caused by freezing. It can be used simply by attaching it to existing piping, without the need for any power sources such as electricity, hydraulic, or pneumatic systems. It easily prevents human errors such as forgetting to open the valve, which can lead to freezing and damage, and protects the piping over the long term. 【Features】 ■ No need for traditional freeze prevention measures like trickling water ■ Robust and long-lasting due to the integrated structure of the temperature sensing and valve components ■ Capable of responding to sudden cold waves ■ The valve opens and closes in response only to temperature, unaffected by fluid pressure ■ Operating temperature range is from 4.4°C (fully closed) to 1.7°C (fully open) *For more details, please refer to the PDF document or feel free to contact us.
