Transcription

1 SC FEPA SA BARLAD BALL VALVES RS-WOG type APPLICATIONS Designed and prepared for use in the underground or above-ground pipeline systems which convey water, oil, natural gas, neutral or potentially corrosive liquids. The products are situated into the category of accessories for pressure regulation and meet the essential requirements regarding the security insurance for the users of under-pressure equipments reglemented by GD 584/004. ADVANTAGES Design in two versions: -demountable or -sealed for life construction in one piece In the demountable version--guaranteed for 0000 actuatings with maintenance program In the sealed for life version-- with no maintenance, guaranteed for minimum 000 actuatings Life minimum 40 years Eterior protection epoy paint, polyurethane insulation, or polyurethane foam insulation and PEHD shell The valves isolated with polyurethane can be used in the pipeline networks with cathodic protection. Over Dn00 in construction Double block and bleed, Special profile of the sealing gasket on the ball the sealing surface increases with the pressure increasing. Anti blow out design, trunnion construction, full bore, bidirectional FUNCTIONAL CHARACTERISTICS Nominal diameter: 5;0;5;;40;50;65;80;00;5;50;00;50;00;50;;500; Nominal pressure: 6;0;6;5 bar Ambient temperature C Kv according to table, pag 6 Sealing class A according to ISO no leakage Relative humidity ma 95% The minimum/maimum temperature of the working fluid -5/80 C but it can be 00 C for short periods of time. Working environment: water regardless of the degree of hardness, oil, gas and other neutral or potentially corrosive fluids, unabrasive Materials: body - carbon steel, stainless steel (AISI 04) or cast iron-only the demountable version ball - stainless steel (AISI 6) ale operation, stainless steel pressing plates (AISI04) elastic elements - W.40 sealing - primary metal/ptfe with 5% carbon Process connections welding ends (the welding does not require local cooling) or flanges Operation: With key/lever up to Dn 50 inclusive, with reductor from Dn 00 inclusive. The reductor can be fied or removable depending on the beneficiary s request. SC FEPA SA tel 05/45990;4466 SG RS- WOG 84/009 Str Republicii nr 6 Fa 05/468;479 rev.0 70 BIRLAD fepa@fepa.ro pag./8
