VARIVENT® Overflow valve

The development of the type D-Force avoids dead ends and unwanted product mix-up areas while providing a clean and hygienic production environment. The present series of overflow valves type Q is now available with a second actuator to support the spring force to close at a higher pressure than the adjusted set pressure by external air support. This is required in almost every product line, in which carbonated drinks are chased by water or vice versa to prevent the product from degassing and foam formation in the pipe, as in every beer filter line and racking line.
