Product catalog summary
Overview: The AMM 755 By-Pass Damper is designed for use in various industrial applications, including CHP and incineration plants, biomass and biogas facilities, power plants, and heat recovery systems. It is suitable for handling air, gas, and fumes.
Specifications: The damper operates at a maximum temperature of 600°C and a maximum pressure of 3 bar, with variations depending on diameter and temperature. It supports diameters from DN 150 to DN 1500, with options for smaller or larger sizes upon request. The damper is available with flanged connections (PN6, PN10, ANSI 150) and can be operated manually or with pneumatic/electric actuators.
Materials: The construction materials include Carbon Steel (S355JOWP - CORTEN A), AISI 304, and AISI 316, with other materials available upon request. The damper is designed for external insulation up to 200 mm.
Standards and Directives: The product complies with several standards, including EN 12516-1, EN 593, and ASME B16.34. It also meets directives such as the Machinery Directive 2006/42/CE, PED 97/23/CE, and ATEX 94/9/CE for Group II Category 3.
Coating and Testing: The damper is coated according to the PSP00 Cycle PS4_PHT, with a RAL 9005 HT silicon coating for carbon steel. Testing follows the AMMtech Quality Control Plan QCP00 and standards like ANSI/FCI70-2 and EN 12266-1.
Flow Coefficient (Kv): The document provides detailed Kv values for various diameters and disc positions, essential for calculating pressure drops and flow variations.
Actuation: The damper can be equipped with pneumatic and electric actuators, conforming to EN 15714 standards. Torque values for actuators are provided, assuming a supply pressure of 5 bar.
Construction Details: The damper features components such as a mechanical open/close indicator, graphite or fiberglass gaskets, and stainless steel bolting. The body and disc materials are available in S355JOWP, AISI 304, and AISI 316.
Additional Information: AMMtech reserves the right to modify products at any time. The document includes a layout code system for configuration and detailed dimensions and weights for various sizes.
