Cv value determination: approximate values air flow rate water Cv value Cv value water Δp = 0,5 bar Δp = 1 bar Cv value air Δp = 0,5 bar, T = 293K, pabs = 6 bar, [m³/h] Δp = 1 bar, T = 293K, pabs = 6 bar, [m³/h] flow rate water With given flow rate, choose your permissible Δp and thus be able to read off your minimum required Cv value. The allocations of Cv values to nominal sizes can be found in the technical charts. Different viscosity? Please request a consultation.

Your safe connection WALTHER-PRAZISION grew from the requirement of its founder, Carl Kurt Walther, to quickly, comfortably and safely connect and disconnect the supply lines of his own manufacturing facilities and range of machinery (Maschinenfabrik Carl Kurt Walther, Wuppertal, founded 1931). Convinced of the technical and economic advantages of the coupling application, WALTHER-PRAZISION started offering the first series on the German market.

Glossary/Technical terminology Directive 2014/34/EU for equipment and protective systems intended for use in potentially explosive atmospheres. For WALTHER quick couplings that comply with this Directive, the part number key is suffixed with -EX. Both sides self-sealing quick coupling, abbreviation used with Cv values and flow volumes Marked products that can be almost completely cleaned from media residues without disassembly. Abbreviation for "Technical Instructions on Air Quality Control" according to VDI 2440. It is the "First General Administrative Regulation Pertaining to the Federal...

Glossary/Technical terminology All WALTHER quick couplings exhibit as standard a sealing performance of 10-3 mbar l/s. Leakage-free connection is in principle physically impossible. Leakage volume The volume released during disconnection. The leakage volume therefore must not be confused with the leak-tightness. The combination of base materials (steel, stainless steel, brass, etc.), sealing materials (NBR, FKM, EPDM, etc.), consumables and supplies (paints, lubricants, etc.) and surface coatings are decisive in determining the properties of the quick coupling. Nominal bore as the diameter...
