KNIFE GATE VALVES -- MODEL AB

DOC. AB.05/08

PRODUCT DESCRIPTION

Wafer style, bidirectional knife gate valve. One piece integral cast body with sliding wedges to provide bidirectional function. High flow rates with low pressure drops. Several seat and packing materials available. Face to face dimension according CMO standard.

GENERAL APPLICATIONS

This knife gate valve is appropriate for clean liquids or liquid with a solids concentration of maximum 4%. Designed for a wide range of applications such us: - Effluent handling plants. - Chemical plants. - Food and beverage. - Sewage applications. In all these applications the installation of the valve is recommended after the fluid is screened to eliminate the solids or big parts contained on it.

TECHNICAL DATA

Standard manufacturing sizes: From DN50 up to DN1200 (bigger sizes under request) Working pressures: From DN 50 to DN 125: 10 (kg/cm2) DN 150: 8 (kg/cm2) DN 200: 7 (kg/cm2) From DN 250 to DN 300: 5 (kg/cm2) From DN 350 to DN 400: 4 (kg/cm2) From DN 450 to DN 600: 3 (kg/cm2) From DN 700 to DN 1200: 2 (kg/cm2) Note : These pressures can be applied either in one side or the other side of the valve because of its bidirectional design. Flange connection drillings: The standard flange connection is according to DIN PN10. Other flange connections such as, ANSI 150, DIN PN6 – PN16 – PN25, British Standard, Australian Standard, JIS Standard, are available under request. Applied Directives: Directive 98/37/CE (machinery), Directive 97/23/CE (PED: Group 2), Directive 94/9/CE (ATEX: Group II, Cat. 3 / Zones 2 and 22) Quality Dossier: All valves are hydrostatically tested at CMO with water and CMO material and test certificates can be provided. Body test pressure = Maximum rated pressure x 1,5 Seat test pressure = Maximum rated pressure x 1,1 C.M.O.
