Tuchenhagen has developed a jacketed valve housing that ensures an optimal heat transmission. A heat transfer medium is carrying heat into the housing so that the entire valve is integrated into the thermal circuit. In this way, products such as chocolate, margarine or similar sensible products can be kept liquid. Amply sized muffs provide for a low pressure drop and optimal flow through the jacketed housing. The jacketed valve housings are available in sizes from DN 25 to DN 100 and form part of our well-known Varivent System. This system can also be used for cold transfer.
