ERV elastische compensatoren.
Rubberen compensatoren worden in het leidingsysteem gebruikt als flexibele verbindingen. ELAFLEX biedt u hiervoor compensatoren van het merk ERV© aan.
ERV-compensatoren bestaan uit een gevormde rubberen balg met 1 golf, drukdragende inlagen en draaiende metalen flenzen. Qua constructie en bouwlengte worden ze internationaal erkend als de standaard.
Door onze ruime voorraad van meer dan 20.000 stuks, kunnen wij u een korte en betrouwbare levertermijn garanderen. Afhankelijk van uw toepassing kiest u de juiste balg (bvb. EPDM, NBR, hypalon of neopreen). Wij kunnen u 13 verschillende types aanbieden, van DN25 tot DN1000, met diverse inbouwlengten (standaard = 130 mm).
Voor onze ERV compensatoren worden enkel Premium Quality balgen van ContiTech Duitsland gebruikt. ELAFLEX en ContiTech staan voor betrouwbaarheid en een lange levensduur.
