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.

The STRATE non-return valve RKS is particularly suitable in areas where the prevention of flap impacts is of particular importance. In this application case the extension of the standard butterfly valve RSK by the additional component STRATE spring load (RSK-FT or RSK-FTU) is required Product features (STRATE RSK) Wide flap to prevent piercing, especially at high pressure levels Type RSK-FT: Equipped with exterior spring load to more quickly close the flap and avoid flap impact Type RSK-UD: Bypass line with pressure shock damping valve to reduce/avoid pressure shocks Type FTUD: a combination of the above types to optimally protect the pumps in case of a power outage, etc.

Due to their special design, 100 % free passage and low flow resistance, STRATE AWASTOP non-return valves are ideal for: Sewage technology, media with solids and coarse solids, sludge (up to 5 % TM) Fresh and service water technology, including in areas where high pressure losses make powerful pumps necessary On request: pumping of fluids deviating from the media listed Areas where quiet operation is particularly important Non-return valves are recognised all over the world as for universal applications in the pumping of fresh water, effluent, sludge and air. Stand for high operational safety Stand out thanks to their excellent value-for-money and low maintenance requirements 100 % free passage Low flow resistance Quiet operation thanks to the inclined valve seat which shortens the closing distance Minimum clogging tendency through optimum hydraulic design− Fail-safe closing of the valve since the closing element is fixed securely into the valve cover

The sliding gate motor valve type 8038 in reinforced design with highresolution fast actuatoris suitable for a wide range of process applications. Media such as steam, liquids, gases, etc. can be handled precisely. The interaction of highprecision control electronics with the precise stepper motor results in a positioning accuracy of ± 0.2% even with a valve stroke of only 6 mm. By means of supercapacitor technology, in the event of a power supply failure, the valve returns to its defined basic position.

PP barrel pump with rigid discharge tube. Barrel pumps made of polypropylene allow a fast transfer of liquids from barrels, canisters and tanks. The good chemical resistance of PP allows acids, alkalis and aggressive detergents to be transferred. The low-mounted non-return valve of the barrel pump and the immersion depth that can be steplessly adjusted using the barrel screw joints ensure good removal of residual liquid. The barrel screw joint fastens the barrel's pump securely to the barrel. Barrel screw joints and thread adapters for commercially available containers are available as optional accessories.
