Non-Return Valves WITT non-return valves protect plants, pipelines and outlet points against reverse gas flow and meet all relevant standards and regulations. The product range of non-return valves includes a large choice of nominal sizes (up to DN200) and flow rates (0.35 – 106 SCFH). The sophisticated valve technology of WITT non-return valves provides small pressure drops making them also suitable for applications with smallest opening pressures. A high-quality sealing system with elastomeres prevents leakages, and dirt filters at the inlet point assure long service life of the non-return valves. Some non-return valve models can also be used as flashback arrestors. All non-return valves can be mounted in any orientation, are available with all connections, in brass and stainless steel and are suitable for almost all technical gases.

Compact, flexible, fixmounted or extendible, and perfectly maintainable. The Motion06 CheckIn, with the CheckIn Premium, is the highest standard of design and functionality. The CheckIn Easy, based loosely on the motto, “less is more”, completes the CheckIn department at the airport base. The whole family of CheckIn is characterised by optimal operability by the operator and optimal accessibility for the passenger. The CheckIn is the passenger’s point of contact with the entire flight baggage system. Whether it be the fixmounted or the extendible version, simple and fast accessibility for maintenance and cleaning work is guaranteed with both. Depending on the feed rate, you can choose from onebelt, twobelt and threebelt systems. The position of the weighing machine also depends on the customer‘s requirements.
