Elpress has a wide variety of ball valves. The connections have a conical thread according ISO 7-1 and DIN 2999-1. The standard ball valves are “blowout proof”.
An Elfoam foam injector is used for inducing and adding chemicals (in-line) to a liquid flow. The induction is caused by vacuum. The pressure of the liquid flow before and after the Elfoam determines the percentage of chemicals added. This percentage is highest when the outflow is unpressurised.
