Designed for use with heat pump systems that are operating with water.

The Zero Anti-Freeze Valve is designed to discharge when the system water temperature drops to 3°C, preventing ice from forming in the heat pump circuit that could cause breakdown or costly damage to the system.

The valve is designed and engineered to avoid negative influences from low ambient temperatures by directly positioning the element in the system water flow, permitting accurate system discharge only when it is truly needed.

Features and benefits:

• A protective ring has been included in the construction to prevent system debris from clogging the operation of the valve.
• Double O-rings and reduced surface friction treatment on the operating member also ensure correct operation and reliability even after years of non-movement.
