Our models 2013 safety units are EN1487 and NF079 compliant. The security valve is with a membrane, it's in order to allow the hot water by the drain outlet when the pressure has reached 7 bar inside the water-heater. It also allows, in case of termic regulation failure, the evacuation of the over-heated water or steam by limiting the overpressur inside the water-heaters to 8.4 bar maximum. Our models 2013 safety units are equiped of a non-return valve and are compliant of the NF and Belgaqua anti-pollution regulation. All our safety units are guaranteed for 2 years from the date of fabrication.

Pressure counterbalancing device
Balancing valve GRK NET
1801
GRK NET EVOLUTION self-cleaning DF threaded balancing valve fitted with a thermowell to receive a probe or a thermometer.
The first control valve specially designed for balancing domestic hot water networks
- Reinforced sealing
- Simplified adjustment with position memory
- Self-cleaning by inversion at 180 ° C of the sphere
- Temperature monitoring by probe or thermometer
Aplications : Centre hospitalier, Clinique, E.P.H.A.D, E.R.P..
| Fight against clogging | Passage section adapted to the flow of fluid and particles. Passage height up to 4 times greater than other valves on the market. |
| Ease of maintenance | System for cleaning the internal passage section by actuating the valve handle. |
| Halth result | As part of regular maintenance, significant reduction in the risk of valve clogging: circulation and temperatures maintained over the long term. |
| Temperature control | Thermowell integrated into the body of the valve for thermometer 1010-1 or probe 1010-2 allowing precise and permanent control of the temperature of the fluid flowing in the valve. Available for GRK NET Evolution DN 15, DN 20 and DN 25. |
Principle of operation
The 180° rotation of the sphere present in the body of the module allows the passage to the particles through the module while keeping the water circulation's way and the module initial's adjustment.
The removal of the particles to the sewer is made through a drain valve placed on the return manifold.
Operating range : 0 to 16 bar.
