2 STRUCTURE 2.1 FITTING STRUCTURE DESCRIPTION F.A. „JAFAR” S.A manufactures cast iron, flanged air valves TYPE 7010 for potable water and industrial systems. They have a cast iron body which houses a loose ball, which is a closing component (float). The ball is made of metal insert fully covered with a rubber layer. The ball is able to float when the valve is filled with water because it has lower density than water. -
Page 5: Materials
During work with a TYPE 7010 valve, the TYPE 7040 valve is a second stage of deaerating when the ball performs repetitive up and down movements, releasing small amounts of air, which builds up in the chamber through the half-open nozzle, with 7010 valve still closed and filled with water (under pressure). - Page 6 PN-EN ISO 4017: 2011 TYPE 7050 Part name Material Standard 7010 valve Like in the table for 7010 Like in the table for 7010 7040 valve Like in the table for 7040 Like in the table for 7040 OPERATION AND MAINTENANCE MANUAL...

4 ASSEMBLY AND INSTALLATION 4.1 INSTALLATION GUIDELINES Cast iron flange valves TYPE 7010, TYPE 7050 and threaded TYPE 7040 can be built over in underground pipelines and above ground vertical systems. Flange valves are adapted to be fitted with pipeline stub pipe flanges with dimensions corresponding with the valve flanges. Valves sized DN50 additionally have a terminal which enables a threaded connection. - Page 13 Before attempting the installation, pipe stoppers should be removed from the main tunnel, state of external surfaces should be checked and, if necessary, rinse them thoroughly with water. Attention! In case of mechanical damage, the device should not be installed on the pipeline. The picture below shows how to install the valve.
