Do not use unstable gasses MATERIALS: The end user should be sure of the comparability of the fluids employed with the material of the valve (metallic parts or elastomers). If in doubt, it should be required the chemical analysis of the used raw material. PRESSURE : Do not use the product over the values of the PN marked on the product. TEMPERATURE: Do not use the product outside the values pressure/temperature expressly marked on the construction normative EN 12328. The valves should be installed following these criteria , any other kind of additional information on the employment of the equipment, in case of doubts should be absolutely requested to Conti Rubinetterie. Assembly To install the valve on the system follow, depending on the connection type, the following instructions: • Threaded Valves: use a sealing for the seat on the threads in accordance with the intercepted fluids. • Flanged valves: use a seat gasket on the flanges and tighten the bolts diagonally. Whatever is the kind of connection ,verify that the ends are free of unknown bodies . The valve can be installed both vertically and horizontally depending on the models. Be careful of the direction of the use of the valve. After the installation be sure that the valve do not suffer any sterss due to the pipes: support therefore the pipes with proper terminals. Maintenance Check periodically that the valves do not leak on the thread. If there are some leakages, contact directly the person in charge of that.
