The cavity chamber is fitted with a vacuum self-drainage system and balancers on each valve discs. For most bodily safety, GEA makes use of the Venturi impact which is created by the particular shape of the flow channels, causing a vacuum on the alternative seal throughout lifting, preventing strain increases. As a outcome, no cleaning liquid can enter the alternative pipe carrying the product while a valve seat is being lifted or cleaned, even if a seal is defective.
When new techniques are arrange and adjusted in a quick while, there is a greater danger of overpressure throughout operation. เพรสเชอร์เกจวัดแรงดันน้ำ must keep in place when water hammer occurs, and the valve must remain closed. For this purpose, GEA has outfitted the valve discs in both pipelines with balancers – stress compensators. This makes the closed valve proof against water hammer up to 50 bar within the higher and lower pipelines. The new MX valve sort additionally has an built-in balancer cleaning gadget. It ensures that the balancer is completely flushed from the outside during seat lifting simultaneously cleaning-in-place is happening. All surfaces involved with the product can be cleaned with none further elements defending the product from contamination.
