v\u00e1lvula de bola de tres piezas<\/a>.<\/p>\nPreguntas frecuentes<\/h2>\n
Does seal-welded mean the valve is welded to the pipe?<\/b> No. Seal-welded refers to the joint between the valve body and its end cap, which is welded at the factory. On V-2B and V-2C the pipe connections are ordinary female threads. The V-2B-SW adds socket weld ends, so that model is also welded to the pipe on site.<\/p>\n
\u00bfCu\u00e1l es la diferencia entre el V-2B y el V-2C?<\/b> Both have the seal-welded two-piece body, full port, PTFE seats and 1000 WOG rating. V-2B has a thicker wall and heavier build for industrial plant lines and comes in 1\/4\u2033\u20133\u2033 (plus a 4\u2033 bolted-cap version); V-2C is the standard-wall grade for plumbing and building services, 1\/4\u2033\u20132\u2033.<\/p>\n
What is the V-2B-SW, and when should I choose socket weld over threads?<\/b> The V-2B-SW is the V-2B body with socket weld ends instead of female threads, 1\/4\u2033\u20134\u2033. Choose threads when the valve may need to be unscrewed and replaced; choose socket weld when the line is welded rather than screwed, or when a threaded joint at the valve is not acceptable. Socket weld is usual on small-bore lines; larger welded lines normally use butt weld ends.<\/p>\n
Which materials are in stock?<\/b> For V-2B, V-2C and the 4\u2033 version, both cast 304 (CF8) and cast 316 (CF8M) are in stock. The V-2B-SW is made to order in either grade. Choose 316 where chloride pitting is a risk, such as coastal or process water with chlorides.<\/p>\n
Which threads can I get?<\/b> Female PT (taper), NPT and PF are all in stock for V-2B, V-2C and the 4\u2033 version \u2014 tell us which standard your piping uses when you request a quote. The V-2B-SW has socket weld ends and no threads.<\/p>\n
\u00bfQu\u00e9 significa \u00ab1000 WOG\u00bb?<\/b> 1000 psi (about 69 bar) cold working pressure for water, oil and gas. Working temperature is \u221220 \u00b0C to +180 \u00b0C, with the PTFE seats setting the upper limit.<\/p>\n
Is the 4\u2033 size also seal-welded?<\/b> It depends on the model. The threaded 4\u2033 (DN100) V-2B uses a bolted end cap, so on the threaded models the seal-welded description applies to 1\/4\u2033\u20133\u2033 only \u2014 see the separate 4\u2033 dimension sheet. The V-2B-SW is seal-welded in every size, 1\/4\u2033 through 4\u2033.<\/p>\n
How should the V-2B-SW be welded in?<\/b> Weld it with the valve fully open. Do not disassemble it \u2014 the body is seal-welded and is not meant to come apart. Keep the body cool while welding: wrap it in a wet cloth, weld in short passes and let the body cool between passes so the PTFE seats are not overheated. Let the valve cool down before operating it.<\/p>\n
\u00bfCu\u00e1l es el pedido m\u00ednimo?<\/b> No minimum order quantity \u2014 we accept orders of any size, including small trial orders, and can supply a mill certificate on request. Payment is by T\/T \u2014 30% on order confirmation, 70% before shipment.<\/p>","protected":false},"excerpt":{"rendered":"
