PTFE seats, manual quarter-turn lever, reduced port, \u221220 \u00b0C to +180 \u00b0C. Two end builds: <strong>femmina \u00d7 femmina (F\u00d7F)<\/strong> da 1\/4\u2033 a 3\u2033, e <strong>maschio \u00d7 femmina (M\u00d7F)<\/strong> da 1\/4\u2033, 3\/8\u2033 e 1\/2\u2033.<\/p>\n<p>Because the body is one piece instead of two or three bolted or screwed sections, there is no body joint \u2014 one fewer place for the valve to leak. The trade-off is honest: it cannot be opened for service, and the bore is one pipe size smaller than the line. We say so plainly further down, and we point you at the valve you should buy instead.<\/p>\n<h2>Cosa significa in realt\u00e0 \"1000 WOG\"<\/h2>\n<p><strong>WOG<\/strong> sta per <strong>Acqua, petrolio, gas<\/strong>. Una potenza nominale di 1000 WOG indica che la valvola \u00e8 progettata per <strong>Pressione di esercizio a freddo, senza urti, pari a 1000 psi<\/strong> on those media.<\/p>\n<p>Three things buyers get wrong about it:<\/p>\n<ul>\n<li><strong>WOG \u00e8 un indice di resistenza al freddo.<\/strong> It is not a steam rating. This valve runs from \u221220 \u00b0C to +180 \u00b0C, set by the PTFE seats \u2014 tell us your line temperature and we will confirm it suits.<\/li>\n<li><strong>\u201cNon-shock\u201d is part of the rating.<\/strong> In una tubazione soggetta a colpi d\u2019ariete o in cui la pompa si avvia bruscamente si verificano picchi di pressione ben superiori alla pressione di esercizio normale. Il dimensionamento deve tenere conto del picco, non del valore indicato dal manometro.<\/li>\n<li><strong>On this valve, \u201cgas\u201d means compressed air.<\/strong> Fuel gas lines (natural gas, propane) call for a gas-listed valve, and this is not one.<\/li>\n<\/ul>\n<p>Se la pressione della vostra linea supera i 1000 psi a freddo, questa valvola non \u00e8 quella giusta: comunicateci la pressione e vi proporremo quella pi\u00f9 adatta.<\/p>\n<h2>F\u00d7F o M\u00d7F \u2014 Quale ti serve?<\/h2>\n<ul>\n<li><strong>Femmina \u00d7 Femmina (F\u00d7F)<\/strong> \u2014 entrambe le estremit\u00e0 sono dotate di un raccordo o di un tubo maschio. La scelta pi\u00f9 versatile, nonch\u00e9 l\u2019unica disponibile per diametri superiori a 1\/2\u2033 (fino a 3\u2033).<\/li>\n<li><strong>Maschio \u00d7 Femmina (M\u00d7F)<\/strong> \u2014 one male end screws straight into a female port, so you save a fitting and shorten the assembly.

That is enough for us to quote.<\/p>\n<h2>Domande frequenti<\/h2>\n<h3>What is a one piece stainless steel ball valve?<\/h3>\n<p>A ball valve whose body is cast as a single piece and welded closed, instead of being bolted or screwed together from two or three sections. There is no body joint, so there is one fewer place for a line to weep. The trade-off is that the valve cannot be opened for service and the port is reduced \u2014 the bore is one pipe size smaller than the line. If you want the same no-body-joint construction with a full-port bore, see the <a href=\"https:\/\/ballvalves.tw\/it\/prodotto\/valvola-a-sfera-a-corpo-saldato-in-2-pezzi-1000-wog\/\">seal-welded two-piece ball valve (V-2B \/ V-2C)<\/a>.<\/p>\n<h3>Cosa significa 1000 WOG?<\/h3>\n<p>WOG stands for Water, Oil, Gas. A 1000 WOG rating means the valve is rated for 1000 psi of cold, non-shock working pressure on those media. It is not a steam rating. On this valve \u201cgas\u201d means compressed air \u2014 it is not listed for fuel gas.<\/p>\n<h3>What is the working temperature range?<\/h3>\n<p>\u221220 \u00b0C to +180 \u00b0C, set by the PTFE seats. Tell us your line temperature and we will confirm the valve suits it.<\/p>\n<h3>Quali taglie sono disponibili?<\/h3>\n<p>Female \u00d7 female (F\u00d7F) from 1\/4\u2033 to 3\u2033 \u2014 1\/4\u2033 to 2\u2033 as standard, 2-1\/2\u2033 and 3\u2033 on request. Male \u00d7 female (M\u00d7F) in 1\/4\u2033, 3\/8\u2033 and 1\/2\u2033. Dimensions are on the two PDF dimension sheets at the top of this page.<\/p>\n<h3>Quali tipi di filettature fornite?<\/h3>\n<p>PT (taper) is the standard thread; NPT and PF are also in stock.<\/p>\n<h3>316 or 304 \u2014 which should I order?<\/h3>\n<p>316 (CF8M) is the stock material and the one to choose wherever chlorides are present: brine, seawater, coastal air, most chemical service. The molybdenum in 316 is what resists chloride pitting. 304 (CF8) is made to order for general water, air and oil duty.<\/p>\n<h3>\u00c8 possibile aprire questa valvola per pulirla o ripararla?<\/h3>\n<p>No. The body is welded, so it cannot be taken apart. That is the trade-off for having no threaded body joint to leak. If you need to service the valve in line, buy the <a href=\"https:\/\/ballvalves.tw\/it\/prodotto\/valvola-a-sfera-3-pezzi-pt-bw-sw\/\">valvola a sfera a tre pezzi<\/a> instead.
