Description
Protection set for central heating pump in case of power outage in the electrical network
40mm=1 1/2 inch
Warranty: 2 years
The set is designed for installation in central heating systems and has been prepared to protect the boiler against sudden increase in temperature and pressure of hot water during power outages or pump failure. During normal pump operation, the differential valve remains closed. When the pump stops working, the check valve automatically opens, allowing gravitational circulation of water from the furnace.
The set described above does not include a central heating pump, which should be selected depending on the building height. The set protects the pump in case of electrical power failure. In such a situation, water in the installation can still circulate through the differential valve, which then allows water to pass without blocking the circulation. The valve must operate in a vertical position. Ball valves mounted on the pump fitting allow the pump to be removed if it is necessary to drain water from the central heating system. The pump is installed on a 1" cross-section.
The set includes:
- cast iron differential valve with rubber ball TECH - POL 1", 1 1/4", 1 1/2", 2"
- ball valve 1" M/F with throttle
- ball valve 1" with filter and throttle
- fittings, pipes
