Isogate WS Series Knife Gate Valve IOM Manual 9 INSTALLATION SUGGESTIONS LOAD DISTRIBUTION RINGS 1. Isogate Knife Gate Valve 2. Load Distribution Ring (LDR) 3. Gasket 4. Pipe Flange 5. Pipe Line __________________________________________ NOTE: If you will be using any of the following style flanges: · Victaulic brand style 741 or similar “grooved to flange” · Vanstone · Stud End · Slip Flanges · Rubber Faced Expansion Joints · Rubber Lined Flanges, please be sure to insert an Isogate Load Distribution Ring between the pipe face and the rubber face of the Isogate Knife Gate Valve. This will prevent your pipe from driving the liner sleeves together, thus enabling the valve gate to operate trouble-free as designed. When the Isogate WS Series Knife Gate Valve is installed with pipe flanges of the following or similar configurations, a Load Distribution Ring (LDR) must be installed between the pipe flanges and the valve. A gasket is required between LDR and metallic or non-rubber coated pipe flanges. Protruding Pipe Protruding Flange Protruding Rubber Liner Victaulic (741) with Raised Faced Flange with ANSI Adaptor Failure to use the LDR when required will result in either over compression or under compression of the sleeve. Both conditions may lead to premature failure of the valve and void the warranty. The LDR provides a safety net to cover a variety of fit-up situations that often occur. The use of flat faced metal flanges welded flush and square will eliminate the need for load distribution rings. Consult the factory or your local Weir Minerals Representative with questions concerning your particular installation. 1 2 3 4 5
