Technical catalogue Manual valves in PVC-U

Developed in 1930 in Germany, PVC-U (rigid polyvinyl chloride - unplasticized) is obtained through the polymerization of a vinyl chloride monomer. The presence of chlorine in the PVC-U molecule results in a high performance resin, in terms of thermal stability and chemical and mechanical resistance, up to temperatures of 60° C. The different formulations obtained by adding suitable additives and stabilizers render the PVC-U the most versatile of all plastic materials, allowing it to be adapted to many applications involving fluids under pressure. PVC-U represents one of the more economic solutions...

Solvent welding Instructions Solvent welding, or cement jointing, is the longitudinal joining system for connecting rigid PVC-U pipes and fittings. The "cementing" is carried out using adhesives/cements obtained by dissolving PVC-U polymer in a solvent mixture. This solvent liquefies the walls of the pipe and/or fitting, allowing the constituent material to chemically combine and be subsequently welded. Chemical welding allows permanent joints be achieved possessing chemical and mechanical strength characteristics identical to those of the pipes and fittings joined. The adhesives/solvent cements...

It is advisable to use an applicator/brush of dimension not less than half the diameter of the pipe. The solvent cement must be applied along the entire length of the joining surface of both the pipe and the fitting: • for the entire joint length of the pipe previously marked on the outer surface (fig. 6) • for the entire depth of the socket as far as the internal shoulder (fig.7) 6) Fully insert the pipe into the fitting immediately and without any rotation. Only after this operation will it be possible to slightly rotate both ends (max. 1/4 of a turn between pipe and fitting). This rotation...

Characteristics and dimensions of brushes-applicators External diameter

• In the case where the external diameter of the pipe and the internal diameter of the fitting are at opposite extremes of their tolerance values, the dry pipe cannot be inserted in the dry socket of the fitting. Insertion will only be possible after having applied the Cleaner and Solvent Cement to both parts to be joined. • The solvent cement is manufactured from the same PVC resin used for the production of the pipes, fittings and valves. Unless otherwise specified, the solvent cement used on the surfaces to join must also be usable with the following tolerances: • When using the Cleaner and...

To guarantee the correct installation of flanged elements, we recommend youperform the following operations: 1. insert the possible backing ring onto the pipe, before proceeding with theinstallation of the stub; 2. in the event of a fixed flange, check the drilling is correctly aligned with the counter flange; 3. check that the position of the counter flange takes into account the overall dimensions of the face to face distance of the components; 4. insert the flat gasket between the stubs (this step is not necessary for butterflyvalves), making sure the sealing surfaces of the flanges to be...

Installation instructions for threaded joints To guarantee the hydraulic seal of the joint on fittings and valves with a threaded female end, we recommend you perform the following operations: 1. Start winding some PTFE sealing tape on the outside of the threaded male end, taking care not to obstruct the through-hole on the pipe, fitting or valve (fig. 1); 2. Complete the first winding layer by winding the tape clockwise until you reach the root of the thread. Remember to keep the tape taut throughout the entire process (fig. 2); 3. Press on the tips of the thread to make sure the tape adheres...
