CHECK VALVES R SERIES - Klinger.dk
CHECK VALVES R SERIES 12/03/2012 WAFER Disc Check Valve ‐ ‐ ‐ ‐ ‐ ‐ WAFER swing or tilting disc check valve (can be manufactured with flanges on request). One‐piece cast body which provides easy evacuation of solid particles contained in the fluid. Face‐to‐face dimension in accordance with CMO standard. It has an arrow on the body indicating the flow direction. Can be supplied with auxiliary spring to obtain faster sealing. For high water loads or large valve diameters hydraulic damping systems can be incorporated which reduce the valve’s impact in the sealing. ‐ The R check valve allows the fluid to flow through in one direction, it is opened by the fluid passing through and it closes due to the weight of the disc and the return of the fluid. General Applications: ‐ This valve is suitable for liquids that contain a maximum of 5% suspended solids. ‐ Designed for a wide range of applications such as: ‐ Paper Industry. ‐ Sewage treatment. ‐ Pumping. ‐ Chemical plants. ‐ Etc. Sizes: ‐ From ND50 to ND1.200. ‐ Larger sizes on request. Working Pressure: ‐ From ND50 to ND600: Maximum PN 64. ‐ From ND700 to ND1.200: Maximum PN 25. Flange connection: ‐ The standard flange connection is according to DIN PN10. Other flange connections are available on request, such as: ‐ ANSI 150. ‐ DIN PN6. ‐ Australian Standard. ‐ PN16. ‐ PN25. ‐ British Standard . ‐ JIS Standard. fig. 1 Directives: ‐ Machinery Directive: DIR 2006/42/EC (MACHINERY). ‐ Pressure Equipment Directive: DIR 97/23/EC (PED) ART.3, P.3. ‐ Potential Explosive Atmospheres Directive: DIR 94/9/CE (ATEX) CAT.3 ZONE 2 and 22 GD. For further information on categories and zones please contact the CMO Technical‐Commercial Dept. Quality Dossier: ‐ All valves are tested hydrostatically at CMO and material and test certificates can be provided. ‐ Body test Maximum working pressure x 1.5. ‐ Seal test Maximum working pressure x 1.1 (Excellent watertight integrity according to AP1 598).

CHECK VALVES R SERIES Advantages of CMO’s "Model R" compared to similar products ‐ Reduced space. ‐ No maintenance needed. ‐ Minimum pressure drops. ‐ Easy assembly. ‐ No spare parts needed. ‐ Minimum leakage with metal/metal seat. tabla1 fig. 2 POS. 1 2 3 4 DESCRIPTION BODY DISC STEM CAP MATERIAL 1 CF8M CF8M AISI316 AISI316 MATERIAL 2 A216WCB AISI304 A216WCB AISI304 AISI304 F‐111 Table 1 1‐ BODY Wafer‐type construction. One‐piece cast body which provides easy evacuation of solid particles contained in the flow. For diameters greater than ND1200 the body is machine‐welded with reinforcements to resist the working pressure. The body’s internal design provides small pressure drops and prevents any build up of solids in the seat area. The standard manufacturing materials are CF8M stainless steel and A216WCB carbon steel (starting from ND250). When the A216WCB carbon steel body is required AISI 304 stainless steel is added to the seat area to ensure a stainless steel metal/metal seat. Other materials such as: GGG50 nodular cast iron and stainless steel alloys (AISI316Ti, Duplex, 254SMO, Uranus B6 ) are available on request. As standard, iron or carbon steel valves are painted with an anti‐ corrosive protection of 80 microns of EPOXY (colour RAL 5015). Other types of anti‐corrosive protections are available on request. 2‐ DISC The standard manufacturing materials are CF8M stainless steel and A216WCB carbon steel.

DISC 3‐ SEAT (fig. 3) This valve is made watertight via contact between the body and the disc. They are both precision machined to ensure the best possible contact. When the valve is manufactured in CF8M stainless steel, the seat is CF8M on the body and CF8M on the disc. When the valve is manufactured in A216WCB carbon steel, AISI 304 stainless steel is added to the seat surface, on the body and the disc. 4‐ STEM BODY fig. 3 Stainless steel seat In check valves manufactured in CF8M stainless steel the stem is supplied in AISI316. In check valves manufactured in A216WCB carbon steel the stem is supplied in AISI304. The stem is supplied in two parts and the valve construction is sealed with a welded cap on the ends. ACCESSORIES AND OPTIONS CMO check valves can be supplied with the following accessories: Spring Loaded Disc (fig. 4): DETAIL OF SHAFT WITH SPRING The valves can be supplied with a stainless steel spring on the stem, which will assist during the closing operation and fig. 4 will increase the closing speed. Counterweight and/or Damper (fig. 5): The counterweight and damper system is used to control the disc closing speed and, at the same time, to reduce the effects of the water hammer. The damper is composed of a hydraulic cylinder and an oil tank which are connected via hydraulic piping. A flow regulating valve is located in the hydraulic piping, to enable the regulation of the oil that fig. 5 moves from one chamber to the other in the cylinder. This flow regulating valve must be installed in such a way that when the valve is opening (cylinder rod extending) it allows the oil to flow through freely whilst when the valve is closing (cylinder rod contracting) the oil flow is cut. The counterweight is used to counteract the friction created by the damper. The arm of the counterweight is a threaded bar on which the position of the weight can be moved and locked via nuts. Note: It is very important to inform our technical department whether the valves should be installed horizontal or vertical piping. C.M.O.
