Bibnose : 45˚ angle
Finishing Red Epoxy
1) Do not neutralize the valve mechanism.
2) Any foreign body should block the openings of the valve. Do not let any viscous fluids or fluids that can leave residue by drying penetrate inside the valve, which would cause a flow jam or block the mechanism.
3) The valve should be installed in a place where there is no risk of shock or water hammer which could damage its working.
4) If the temperature is lower than 0°C or superior to 60°C, it is necessary to insulate the material and authorize its access only to the authorized staff. For the material, it is imperative to stay in a temperature indicated on the identification plate (Rep. 3) or failing on the product data sheet.
5) It is imperative to respect the defined conditions announced by our staff (pressure, temperature, and fluid). Do not use corrosive fluid or fluid likely to provoke a significant wear, no unstable fluid with risky decomposition; do not use several fluids which could react altogether or release derivatives leading to an explosive atmosphere and no viscous fluid likely to solidify at one moment or another.
6) Limit as much as possible the tensions due to failure alignments of the piping connections system.
7) It is necessary to eliminate any previous and post pressure before removing the valve and be sure not to create an explosive inside or outside the valve. The staff operating the setting up of the valve will be trained to perform this operation and will wear all necessary protections linked to the carried fluid.
8) Do not let the mechanism in an intermediate position for a long time to avoid any phenomenon of cavitation and/or erosion.
9) Do not modify the documents.
Operating / Maintenance
1) It is imperative to maintain the valve clean and in good working conditions. It is necessary to check periodically that no foreign body blocks the piping and that the installation is free of deposits and impurities.
2) The packing gland system (parts 12, 13 and 14 or 38) is assembled by our staff in our factory. However, during the valve’s lifetime, it can be necessary to tighten the packing nut 14 (or screws 38 for references 3198 and 3202); or to replace the packing 12. Before you perform this operation, take care to let the material come back to an ambient temperature and make sure that the installation is correctly bleeded. Untighten the nut 40, remove the wheel 8, undo the packing nut 14 (or screws 38 for references 3198 and 3202), remove the packing gland 13, remove the packing 12, set up the new packing inside the bonnet 2, put the packing gland 13 back on, screw the packing nut 14 (or screws 38 for references 3198 and 3202), set the wheel 8 back and screw the nut 40. The packing gland systems must be tightened when the valve is going to be used and just enough to ensure tightness.
