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. > 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. > 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.

The main characteristic of this knife gate valve is the body design. It is a one piece machined cast body with wedges in both sides that provides the capability to work with flow in both directions at the same pressure. The sealing joint has an internal stainless steel wire that helps the joint to keep the body shape and avoid its dismantling. This design provides a completely flat seat with no cavities and avoids any build up of solids in the seat area. The stem protection hood is independent from the hand wheel fixing system, so the hood can be removed without removing the hand wheel. This...

Wafer style, one piece mono block cast body with sliding wedges to provide bidirectional function. For sizes bigger than DN600 the construction of the body is fabricated with two bolted parts in carbon steel with reinforcement ribs to withstand the maximum rated pressure. Full port designed to provide high flow rates with low pressure drops. The internal design of the valve avoids any build up of solids on the sealing area. The standard manufacturing materials are GG25 cast iron and CF8M stainless steel. Other materials like GGG50 nodular cast iron, A216WCB carbon steel and stainless steel alloys...

DOC. AB.05/08 Resilient Seat Materials EPDM This is the standard resilient seat installed on CMO valves. It can be used in many applications, but generally it is used for water and products diluited in water at temperatures not higher than 90C.The EPDM rubber can also be used for abrasive products. It provides 100% tightness. NITRILE It is used for greasy fluids or oils at temperatures not higher than 90 ںC. It provides 100% tightness. VITON Appropriate for corrosive products and high temperatures up to 190C in continuous and picks of 210ںC. It provides 100% tightness. SYLICONE The silicone is...

DOC. AB.05/08 GRAPHITE FILAMENT It is made of graphite threads of high purity. It is braided by the diagonal system and impregnated with a small quantity of graphite and lubricant which helps to reduce the porosity and makes easier the running. It is a packing with low friction coefficient and high heat conductivity. Is has a wide range of applications, as the graphite withstands the steam, water, oils, solvents, alkalis and most of the acids. The chemical products that attack this packing are strong oxifiers as the oleum, the fuming nitric acids, the diochramates and the oxygene. P(bar) = 40...

Several types of accessories are available to adapt the valve to specific working conditions, such as: Mechanical Limit Switches, Inductive Switches and Positioners Limit switches for punctual valve position indication and positioners for continuous valve position indication. Solenoid valves For air distribution into pneumatic actuators Connection electrical boxes, electrical wiring and pneumatic piping Completely assembled units with all accessories can be supplied. Allows the locking of the valve in a fixed position during long periods Stroke limiting mechanical stops Mechanical locking device...

DOC. AB.05/08 Double acting actuator: For valves of diameter DN50 up to DN200 the cylinder jacket and the caps are in aluminium, the piston rod in AISI304, the cylinder piston in steel covered by nitrile and the o-rings in nitrile. For valves bigger than DN200 the caps are manufactured in nodular cast iron or carbon steel. The actuator can be manufactured fully in stainless steel under request and specially for very corrosive ambient. Single acting actuator: Fail close or fail open single actuators are available (spring to close or spring to open). For all size of valves the cylinder jacket is...
