Thanks to the large surface area of the diaphragm, this style spunding valve is much more accurate than the poppet style. 8 mm Duotight fittings at both inlet and outlet make this unit perfect for use with EVABarrier 8 mm OD tubing.\u003c\/p\u003e\n\u003cp\u003eThe BlowTie 2 features an integrated pressure gauge so you can quickly and easily dial in your pressure setting. The analog gauge is removable and can be swapped out with a gauge of a different pressure range or it can be swapped out for the digital mini pressure guage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePressure Fermentation\u003c\/strong\u003e\u003cbr\u003ePressure fermentation is becoming more and more popular at the homebrew level, but in order to do it safely and accurately you need a way to release excess pressure. You'll pressurize your vessel to your desired psi, but once fermentation begins and those hungry, active yeast start creating CO2, the pressure inside the vessel will increase. Attach a spunding valve and set it to your desired pressure, and it will blow off when the pressure gets too high and close up again when it's back to your desired psi.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePressure Transfers\u003c\/strong\u003e\u003cbr\u003eEven if you don't have a pressurizable fermenter, you may have done pressure transfers from keg to keg during filtering or after fining. During pressure transfers, it's a good idea to have a bit of head pressure in the receiving keg, especially if you're transferring beer that is already carbonated. Having a spunding valve in place will allow you to consistently control the head pressure and give you more consistent results, without losing carbonation in the process.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSet Up\u003c\/strong\u003e\u003cbr\u003eThe BlowTie spunding valve comes with 8 mm Duotight fittings on the inlet and outlet, and we recommend using it with EVABarrier 8 mm OD tubing. You'll also need the flare Duotight fitting in order to attach it to a ball lock or pin lock disconnect. Dialing in your desired pressure is even easier with the BlowTie 2, thanks to the integrated pressure gauge. Simply start with the adjustment knob fully closed, then slowly open it until the gauge reading matches your desired pressure setting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eMade from food grade acetal\u003c\/li\u003e\n\u003cli\u003eStainless screws\u003c\/li\u003e\n\u003cli\u003eEasily disassembles for cleaning\u003c\/li\u003e\n\u003cli\u003e8mm (5\/16\") Duotight fittings at both ends\u003c\/li\u003e\n\u003cli\u003eInterchangeable pressure gauge\u003c\/li\u003e\n\u003cli\u003eGauge reads from 0-15 psi\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Corny Keg","offers":[{"title":"Default Title","offer_id":43575293837538,"sku":"BMFE962","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0511\/3511\/9550\/products\/CK-SPUNDINGVALVE1.jpg?v=1667237230","url":"https:\/\/cornykeg.com\/products\/blowtie-2-diaphragm-spunding-valve-with-gauge","provider":"Corny Keg","version":"1.0","type":"link"}
