EUnited Valves (The European Valve Manufacturers Association set up in Brussels) has prepared a classification system for products that manage home comfort and water responsibly in the residential sector, more specifically, for thermostatic valves.
 
 
Caleffi thermostatic control heads, item numbers 200000 and 201000, were included in the list of TELL-approved (Thermostatic Efficiency Label) products.
Both commands were placed in the A efficiency class.
 
 
TELL approval is awarded on the basis of the following criteria:
- water temperature;
- hysteresis;
- response time to changes in temperature;
- differential pressure.
 
 
 

Caleffi proved yet again that its products are perfectly in line with international standards, one of the pillars of the company's quality policy.
