Diversity, safety, performance

20,000 prod­ucts in more than 200,000 vari­ants! A com­pre­hen­sive, high-per­for­mance range of valves for the process indus­try – built to com­ply with the high­est qual­i­ty stan­dards accord­ing to DIN ISO 9001–2015. Ari-Arma­turen will be show­cas­ing an impres­sive vari­ety of inno­v­a­tive prod­ucts at Achema 2018 (Hall 8.0, Stand B45).
The butt weld end ver­sion of Zetrix, the metal­lic seal­ing, triple off­set pre­mi­um process valve, is a new addi­tion to the Ari range. It is avail­able in sizes DN 80 to DN 600 for PN 6 to PN 40 (class 150/300). Also new from the com­pa­ny: the ful­ly lugged, wafer flange ver­sion is now addi­tion­al­ly offered in DN 80 to 600 for PN 63/100 (class 600). For sev­er­al years, this sophis­ti­cat­ed range of process valves with metal­lic seal­ing and a self-align­ing seal­ing ring has been round­ed off with a dou­ble flanged ver­sion. Zetrix valves com­bine extreme reli­a­bil­i­ty and dura­bil­i­ty. All mod­els have a stel­lit­ed seat and are fire­safe test­ed with bidi­rec­tion­al gas-tight shut-off and zero leak­age accord­ing to EN 12266–1 and API 598.
Every­thing is pos­si­ble with the new Ste­vi Vario – the vari­able, com­pact con­trol valve which impress­es with its enor­mous diver­si­ty. In par­tic­u­lar, the change­able, vari­able trim and the dif­fer­ent actu­a­tor designs pro­vide users with incred­i­ble flex­i­bil­i­ty. The Ste­vi Pro high-per­for­mance con­trol valve for pro­fes­sion­al con­trol, espe­cial­ly in crit­i­cal appli­ca­tions, fur­ther extends the range. The stain­less steel vari­ant can now also be sup­plied by the com­pa­ny with a stain­less steel bel­lows. With its opti­mised char­ac­ter­is­tic qual­i­ty, high pre­ci­sion and per­for­mance are guar­an­teed. And thanks to the blow-out proof stem and shaft guid­ed plug – as well as a two-ply bel­lows seal on request – the Ste­vi Pro is safe even in harsh indus­tri­al environments.
The bel­lows valve range, already very ver­sa­tile, has like­wise been expand­ed. For the first time, the firm can now offer the process indus­try Faba Supra MD bel­lows valves for PN 63 to PN 160. When fit­ted with a bal­anc­ing plug, these valves are even safer to use (option­al from DN 65). They are reli­ably tight, even at high pres­sures, owing to the bel­lows seal, ser­rat­ed seal and stel­lit­ed mar­gin­al plug (ide­al hard­ness gra­di­ent: Stel­lite 6 / Stel­lite 21).
The safe­ty valves prod­uct group has been extend­ed yet again. In future, cus­tomers can now option­al­ly order any Safe valve in stain­less steel – up to size DN 250 includ­ing a stain­less steel bel­lows. The bel­lows not only pro­vides back­pres­sure com­pen­sa­tion; it also seals and pro­tects the spring cham­ber and the guides. The two-fold safe­ty due to the sep­a­rate bal­anced pis­ton, which acts redun­dant­ly with the bel­lows and is sup­plied as a stan­dard fea­ture at no extra cost, is a anoth­er deci­sive advan­tage! Increased safe­ty is pos­si­ble on request in the form of two com­bi­na­tions: Safe Combi‑C (change-over valves) and Safe Combi‑R (rup­ture discs).
The large Cona fam­i­ly of steam traps has acquired new mem­bers too: in addi­tion to the estab­lished range of bimetal­lic, ball float, diaphragm cap­sule and ther­mo­dy­nam­ic traps, the com­pa­ny can in future also sup­ply a com­pact Cona S ball float steam trap for high­er con­den­sate vol­umes as well as the famil­iar Con­lift con­den­sate pump – now also in stain­less steel or with a cast steel body.
If the vol­ume of con­den­sate exceeds 10,000 kg/h and the pres­sure con­di­tions are prob­lem­at­ic, with dif­fer­en­tial pres­sures up to 32 bar, Cona S makes a good alter­na­tive.  With its stan­dard face-to-face dimen­sions, 13, 21 and 32 bar dif­fer­en­tial pres­sures and all the usu­al approvals for the inter­na­tion­al mar­kets, it is a high­ly ver­sa­tile prod­uct for (large-scale) plant man­u­fac­tur­ing. The robust lever and ball design is in keep­ing with the firm’s strong com­mit­ment to qual­i­ty and the foun­da­tion for a long life.
The process indus­try can prof­it from more prod­uct diver­si­ty when it comes to con­den­sate pumps. The slight­ly mod­i­fied design means that few­er dead spaces have to be filled with steam, so that less motive steam is required. The cast steel vari­ant is more­over lighter and fea­tures a new con­troller for 14 bar dif­fer­en­tial pres­sure. The new Con­lift design in cor­ro­sion-resis­tant, long-last­ing stain­less steel opens up addi­tion­al appli­ca­tions in the process industry.
This extreme­ly ver­sa­tile and sophis­ti­cat­ed range for the process indus­try is round­ed off with var­i­ous sys­tems – such as PREsys (for pres­sure reduc­tion), CORsys (for con­den­sate recov­ery and return) or ENCOsys (for heat exchange).
Speed, exper­tise and depend­abil­i­ty, with all prod­ucts built to com­ply with the high­est qual­i­ty stan­dards accord­ing to DIN ISO 9001 – this is the promise the com­pa­ny makes to its cus­tomers! Final­ly, myValve – the valve siz­ing pro­gram – is an intu­itive soft­ware pack­age pro­vid­ing access to all impor­tant infor­ma­tion on the entire port­fo­lio as well as all essen­tial siz­ing cal­cu­la­tions when­ev­er they are needed.
