You will find a list of our distributors at PRESSURE-TIGHT CONNECTIONS IN SECONDS In times of intense cost pressure more and more companies pose the question How to organise production processes even faster and cheaper and at the same time increase safety and comfort in the operation? WEH offers the optimum solutions with their quick connectors. Pressure- and function-tight connections can be made in seconds. Unique WEH Jaw locking mechanism ll quick connectors have the unique WEH Jaw locking mechanism developed by WEH. The jaw locking system is superior to ball locking systems in that it tolerates dirt and reduces wear on the test piece. Connections in seconds WEH Connectors are simply placed onto / over or into the inlet of the test piece and the pressure-tight connection is immediate. Laborious thread connections and tightening of pressure test hoses is no longer needed and intricate testing devices are a thing of the past. The connectors are designed for pressures up to several 1000 bar depending on connection type and test piece. In comparison to threaded connections there are significant time and cost reductions due to the efficient design of WEH Connectors. 6 D-2011/09/

Note: t higher operating temperatures the permissible operating pressure has to be reduced accordingly to compensate for the effect of heat weakening component materials. Example values see table: Technical notes Pressure - temperature - compensation The admissible operating pressure has been determined as follows: 100,000 x cycles impacting the component with 125 % of PN The pressure wave is sinusoidal.

83 Technical appendix Technical notes Term Temperature range Leak rate Max. side load Pressure - temperature - compensation Suitability for application WEH connectors with pneumatic actuation Definition The temperature ranges stated cover most common applications. The seal material used has higher or lower temperature limits dependant on material (e.g. NBR -30 C up to +100 C, FKM -20 C up to +200 C, EPDM -40 C up to +150 C). Under such extreme temperature conditions the suitability of WEH Products to the application has to be checked specifically. If necessary, we can develop special solutions. Leak rate: 1 x 10-3 mbar x l/s This is the minimum leak rate. We are able to offer units with significantly lower leak rates on request. This depends on the customers specifications (test mode, test temperature, test pressure) and the quality of the customer s sample (e.g. surface finish and dimensional tolerances). External forces can considerably shorten the lifetime of the connector, or cause malfunctions. Tensile and transverse loads need to be considered such as mounted technical devices etc. as well as vibrations and pressure impacts. Lateral forces such as whipping hoses or other equipment must be avoided. WEH Connectors should be installed in such a way, that lateral forces which could lead to leakage can not occur. Special applications require a special consultation before selecting the connector. For higher temperatures the max. operating pressure needs to be reduced dependant on the application. Possible values therefore are: 50 C - 5 %, 100 C - 10 %, 150 C - 20 %. In case of doubt, please contact us! When using certain materials, for example plastics, the valves need to be further derated. When selecting a component, the total system design must be considered to ensure safe, trouble free performance. The correct selection of a component, material, temperature, pressure range as well as proper installation, operation and maintenance are the responsibility of the customer. The customer has to ensure there is adequate axial movement when pneumatically actuated WEH Connectors are used in automated systems. Ideally the connectors should be mounted with a floating joint or introduced individually to prevent the clamping jaws getting blocked or jammed in the thread of the test piece. Contact WEH for the relevant installation instructions for pneumatically actuated WEH Connectors in automated systems. OVERVIEW SELING MTERIL The WEH Connectors can be adapted to your specific application. large variety of sealing materials is available for this purpose. Together with the supplier of the sealing material we choose the right material suitable for your medium. If extremely high temperatures are prevailing we also use metallic seals. For seals that are not being directly exposed to the media - NBR is used, if not otherwise stated. Sealing material Suited for Note NBR (e.g. Perbunan) FPM, FKM Mineral oils, air, water Mineral oils, petrol, super petrol, diesel oils, air Not for water over 80 C! EPDM Hot water, steam, brake fluid Not resistant for mineral oils! Urethane Mineral oils, air Not for water over 50 C! This list only contains a small selection of suitable media. If your media is not listed, please contact us. Other seal materials can be specified on request. D-2011/09/

84 6 Further Information 6.2 Brochure Data Brochure data Maximum care has been taken compiling this catalogue based on many years of experience. However we must point out, that all catalogue data is only valid, if it was expressly confirmed in the individual order. We cannot guarantee the veracity of the data and the introductions in individual cases due to the large variety of applications for WEH Products, and the unknown parameters and conditions of use. We have to refer to the individual order. The limits of use for pressure, temperature etc. in this catalogue are theoretical data calculated on the basis of tests. Because of different operating conditions we cannot guarantee that the data do accord with the special use of the client. It has to be considered, that in the practical use interactive interferences of data parameters can cause the change of the maximum values. Especially if the operating conditions are extreme, the WEH company must be consulted before the use of the products. Therefore the requested values should be stated in the individual order, especially for extreme operating conditions. Furthermore we point out, that we cannot guarantee for misprints, uncompleted data or misinterpretation. The illustration of the products is for demonstration only. The exact form and design of the product is only defined by the individual order. The brochure is only an integral part of the contract, if it is agreed expressly. Dimensions and other technical data in this catalogue are without obligation. By the transfer of an up to date brochure or document all precursory versions will run out of validity. s a matter of principle the latest up to date version of brochures and other documents are valid. These versions can be inquired by the WEH company.
