2004 EDITION VP-2/9 www.orbinox.com MODEL VP 0.- DESCRIPTION The VP model knife gate is a through-conduit bi-directional wafer valve designed for high consistency fluids. The double seat design assures a non-clogging shut off on either normal or reverse flow. 1.- HANDLING When handling an Orbinox valve please pay attention to the following points: ? Do NOT attach lifting gear to the valve actuators or gate guards. They are not designed to bear the weight, and could easily be damaged. ? Do NOT lift the valve by the valve bore. This can cause damage to the seating surfaces and seals. Ideally when using lifting gear to move an Orbinox valve, it should be supported by two or more eyebolts screwed into the tapped fixing holes in the valve body. SAFETY WARNING: ? Check that the lifting gear is rated to carry the weight of the valve. ? Make sure the eyebolts have the same thread as the boltholes and that they are well secured. During installation it is recommended to lift the valve via soft straps. These can be to the upper part of the valve body. 2.- INSTALLATION To avoid personal injury or damage to property from the release of process fluid: - Those in charge of handling and maintenance of the valve must be qualified and trained in valve operations. - Use appropriate personal protection equipment (gloves, safety shoes, etc). - Shut off all operating lines to the valve and place a warning sign. - Isolate the valve completely from the process. - Release process pressure. - Drain the process fluid from the valve. Before installation, inspect the valve body and components for any damage that may have occurred during shipping or storage. Make sure the internal cavities within the valve body are clean. Inspect the pipeline and mating flanges, making sure the pipe is free of foreign material and that the flanges are clean. The VP valve is bi-directional. Both standard (Type A) and reinforced construction (Type B) can be installed without taking the direction of fluid into consideration. However, valves provided with a deflection cone (Type C) are unidirectional. It is vital that they be installed correctly with respect to the direction of the flow. Correct installation is the responsibility of the user. .

2004 EDITION VP-3/9 www.orbinox.com MODEL VP Special care should be taken to maintain the correct distance between the flanges and to ensure that they are parallel to the valve body. Incorrect alignment of the valve can cause deformations, which can lead to difficulties in operation. Place the valve between flanges. First tighten the side bolts (1) and then the upper and lower bolts (2). The following table gives the maximum torque values for the valve fixing bolts. Also shown is the maximum depth (T) allowed for the tapped blind boltholes drilled into the valve body. DN
