RESPONSIBILITY FOR VALVE APPLICATION The User is responsible for ordering the correct valves. APV Valves are to be installed in the observance of the pressure rating and design temperature. Prior to installation, the valves and nameplates should be checked for proper identification to be sure the valve is of the proper type, material and is of a suitable pressure class and temperature limit to satisfy the applications requirements.
This manual describes the methods of installation and maintenance for lined butterfly valves. APV refuses any liability for damage to people, property or plant as well as loss of production and loss of income under any circumstances but especially if caused by: Incorrect installation or utilisation of the valve or if the valve installed is not fit for intended purpose.
HIGH PERFORMANCE BUTTERFLY VALVES - MODEL SLHBF & SLHBFFS DURING OPERATION BEAR IN MIND THE FOLLOWING WARNINGS: a- The graphoil packing and body gasket is very brittle: any twisting or bending shall be avoided. b- The internal parts of valves (disc, stem, seat) shall be handled with care avoiding scratches or surface damage.

HIGH PERFORMANCE BUTTERFLY VALVES - MODEL SLHBF & SLHBFFS DIAGRAM 1 Lug Type Wafer Type Flange Type 1.3 SCOPE This manual describes the methods of installation and maintenance for high performance butterfly valves. 2 . 0 S T O R A G E 2.1 TEMPORARY STORAGE If valves are to be stored before installation, the following should be observed: a) Keep the valves wrapped and protected as shipped from the manufacturer.
HIGH PERFORMANCE BUTTERFLY VALVES - MODEL SLHBF & SLHBFFS 2.3 PREPARATION If storage in the field for a long time before installation is necessary, it is suggested to put valves in a dry and/or covered place. In this case the packaging and end covers integrity is especially important. All the valves are supplied with special plastic ends to cover and protect the internal parts.
HIGH PERFORMANCE BUTTERFLY VALVES - MODEL SLHBF & SLHBFFS 3.1 MANUAL OPERATION Valve adjustment is performed by clockwise turning of the stem. Lever operated and gear operated valves have a position indicator to indicate open or closed (see Diagram 2). Normal isolation butterfly valves are not designed to be used for throttling.

Refer to dimensions on APV drawing. – Prior to installation the valve and the down-stream pipeline have to be thoroughly cleaned of any contamination, especially of hard foreign substances.
HIGH PERFORMANCE BUTTERFLY VALVES - MODEL SLHBF & SLHBFFS Valves with a short face-to-face dimension have to be mounted with disc in closed position otherwise the valve disc could be damaged. 4.5 SAFETY PRECAUTIONS - Ensure the line is depressurised and drained. - Check the pipeline media.
HIGH PERFORMANCE BUTTERFLY VALVES - MODEL SLHBF & SLHBFFS The valve will operate in both directions, however, the valve must be installed so flow is in the direction indicated on the body as the valve is designed to isolate flow from one direction. If you require bi- directional isolation it must be specified when ordering, even a preferred flow direction may still be indicated.
HIGH PERFORMANCE BUTTERFLY VALVES - MODEL SLHBF & SLHBFFS seating surfaces during valve operation. • Verify that the space available for installation is adequate to allow the valve to be installed and to be operated. Ensure sufficient clearance for the stem in the full open position. Inadequate clearance for valves may add mechanical loading to the valve ends.
