Operation for the 28mm Valve
The Inta Zero is a unique antifreeze valve to protect heat pump
systems that are operating with water. Designed to discharge
when the system water temperature goes down to 3°C preventing
ice from forming in the heat pump circuit that could cause
breakdown or costly damage to the system.
The Inta Zero has been 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 its truly needed. A protective ring has been
added to the construction to prevent system debris clogging the
operation of the valve. Double o-rings and reduced surface friction
treatment on the operating member also ensure correct operation
and reliability time after time.
