Send us the floor plan and the equipment list and we will mark up where the isolation valves belong, which ones should be kits and which ones valve only, and quote the lot. Getting the valve layout right at design stage is the single cheapest thing you can do for future maintenance.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eWhat exactly is in the complete kit?\u003c\/h3\u003e\u003cp\u003eChampion's price list describes the 73mm, 90mm and 115mm kits as the valve plus two threaded adapters, two stainless flanges and two couplings with bolts. The 168mm and 220mm kits are listed as the valve with flanges and bolts, without adapters, which matches how the flange kits work at those sizes. If the exact contents matter for your bill of material, ask us and we will have it confirmed before the order goes in.\u003c\/p\u003e\u003ch3\u003eIs there a high temperature version?\u003c\/h3\u003e\u003cp\u003eChampion lists high temperature butterfly valves at all five sizes as consult factory, with no list price. We will not invent one. If you need an isolation valve upstream of the aftercooler, call or email and we will have the factory quote it.\u003c\/p\u003e\u003ch3\u003eWhy does the price list describe the 168mm kit as 68mm?\u003c\/h3\u003e\u003cp\u003eBecause of a typographical error in Champion's current price list. The 168mm kit prints as 68mm and the 220mm kit prints as 115mm. The part numbers and the prices are internally consistent and ascend correctly with size, so we have built this listing to the part numbers rather than to the descriptions, and flagged it to Champion.\u003c\/p\u003e\u003ch3\u003eWhat pressure is the valve rated to?\u003c\/h3\u003e\u003cp\u003eNot published in the price list, and we have not found a Big-Lock valve datasheet. We are not going to quote a figure from a similar valve and present it as Champion's. Ask us and we will confirm with the factory, which matters here because these are no-return items.\u003c\/p\u003e\u003ch3\u003eCan I install the valve in any orientation?\u003c\/h3\u003e\u003cp\u003eGenerally yes for a butterfly valve on clean, dry air, though stem horizontal is the conventional choice so that any condensate does not sit on the seat. On a line that carries liquid water, fix the drainage problem rather than working around it with valve orientation.\u003c\/p\u003e\u003ch3\u003eIs there a 273mm valve?\u003c\/h3\u003e\u003cp\u003eNot in the current price list.
