AWH Catalogue ValveTechnology - Neumo

1 Armaturenwerk H tensleben GmbHValve Valves for all PurposesEHEDG Certificate Type EL-class IThe EHEDG certifies plant components that are suited for cleaning with liquids. This certificate is based on the EHEDG recommendation No. 8 Hygienic Design Criteria . AWH butterfly valves are certified with type EL-class I. Type EL stands for equipment for liquid use . Class I means that it is suitable for CIP processing. This certificate applies to the entire range of AWH butterfly valves with the nominal diameters DN10 - 200 and 1" - 4" of the series B with EPDM and Viton sealings. ATEX versionnow available! Armaturenwerk H tensleben GmbH takes pleasure in presenting the revised Catalogue of the extended range of valves.

2 On the basis of the disc valve, we are describing the AWH product with its versatile variants and related following innovations are specified in this Catalogue :- the Inch - butterfly valve program with nominal diameters ranging from 1" to 4" with smooth passage- EHEDG certificate of the butterfly valve program with EPDM and Viton seals- the butterfly valves DN10 - 20 as real straight-through valve without reduction- the distribution valve as alternative to the cross-point panel- modification of the check valves to a double guided valve plateATEX Butterfly Valve:Definition:Due to the expiration of the transition period for the guideline 94/0/EC (ATEX) dated June 30th, 2003, now also the non-electrical devices apply to the evaluation procedure of evaluation of conformity implies initially an ATEX analysis including an ignition hazard evaluation (acc.)

3 To EN 13463-1:2001, non-electrical appliances for use in explosive environments, Part 1: Basic Methodology and Requirements).If this evaluation determines that there is no ignition hazard or the definitions for the devices and components acc. to the guideline 94/9/EC do not apply, then the application of the guideline is not required. AWH Butterfly Valve:The butterfly valves are differentiated into an outer and inner area. The inner area is defined as the product inside the pipe. The manual control or drive are assigned to the outer area:According to the expert s report AWH s butterfly valves with EPDM/VMQ/FPM center sealings can be applied within the product-affected area without restriction for all ATEX area:The handle is not a device in terms of the guidelines, thus no restric-tions are pneumatic actuator (air/spring and air/air for the nominal widths DN25 - 100 as well as DN125 - 200) have been examined according to the ATEX guidline and are marked as follows:These may be used in potentially explosive operating sites in zone 1 and zone 21.

4 For these applications we also offer appropriate check-back signals with approvals for zone 1 , 2 and 22 as additional order to be distinguished from the standard program, the compo-nents are marked with ex and always equipped with a conductive 2GD c IIB T135 C (T4)5 C Ta 45 Handles, Sealings and EquipmentPage 4 Actuators and Equipment Page 5 Butterfly Valves Page 6 Configuration Options Handles
