1 utterfly valves JM The multi-purpose industrial butterfly valve. Features and enefits Due to its robust design, the JM is a PN25 rated butterfly valve. Top flange standardized to adapt any type of actuator, conform to ISO 5211 standard. hevron seal made in nitrile, avoiding atmospheric contamination. Self lubricating bearings made of PTF reinforced on a metallic support. These bearings provide a true shaft guide and ensure absolute shaft rigidity during operation. Shaft inside the disc, it is completely insulated from the liquid being conveyed. Standard ductile iron body, providing higher mechanical properties. Removable elastomer seat, completely covering the inside of the body. enticular shape disc, improving the flow capacity. It has no internal attachments or pins to avoid corrosion and internal leakage. The centered disc allows bidirectional shut-off. entering lugs enable the disassembly of the downstream pipeline, and maintenance of the valve at the end of the pipe. The full lugged type ensures the mounting at the end of the pipe under maximum pressure. ll valves are in accordance with international standards such as TX, PD and TPD. pplications eneral utilities Water treatment and distribution ement plants Mechanical engineering Mining industries Steel and aluminium plants Food industries Sugar refineries Shipbuilding and offshore Pulp and paper mills utomotive industries hemical - Petrochemical Power generation Heating, Ventilating and ir conditioning as process Fire protection systems griculture - Irrigation ulk handling fluids Sapag reserves the right to change the contents without notice SHFR-0008-N-0406

Pull out the protection plug Remove the V Ring seal Unscrew and remove the safety nut xtract the control shaft 3 and its thru-bolt 10 after having placed the disc 2 in open position and located the orientation of the key 11 (for sizes 10 to mm to 1000 mm). 6. Remove the spindle Remove the disc Displace the seat 5 from the center by extracting one of the two journals from its housing. This operation will allow the lateral disengagement of the body seat. 2. Remounting the seat 1. Make sure the coupling 12 is in the body for DN 50 to Do not grease either the outside of the seat or the inside of the body. 3. Deform the seat 5 and insert one of the two spherical journals free in its body housing. Spread out the two lateral seat lips correctly on the grooved body faces. Place the central part of the seat properly in the grooved body. Put the second spherical journal in position. Make sure the liner is well placed around its periphery. 4. rease the following parts lightly (Ref. compound type 111 from Dow orning Silicone rease. - The inside of the seat and more particularly the two spherical journals. - long the control shaft as well as its extremity connected with the disc. - long the spindle. 5. Remount the disc 2 in the open position. e sure that the female part of the disc connecting with the shaft is on mounting flange side. 6. e sure that body and disc machining is in line. 7.
