Diaphragms have their place (we use them in our wastegates), as they offer low friction and good sealing capability. However, a rolling diaphragm is only designed to receive a net pressure on one side, which essentially “inflates” it against the walls of the chamber in which it resides, exactly how it is used in a wastegate.\u003c\/p\u003e\n\u003cp\u003eHowever, a BOV is exposed to frequent pressure reversals – every time you accelerate and lift off.\u003cbr\u003eFor a diaphragm, this means it is repeatedly collapsing on itself under boost, then inflating under vacuum. Eventually, this leads to diaphragm failure. A piston on the other hand is immune to this issue, and will continue to operate under the most extreme pressure, temperature, and cyclic conditions.\u003c\/p\u003e\n\u003cp\u003eThe unique mounting method of the SV52 is one of the ways we’ve been able to save unnecessary bulk.\u003cbr\u003eBy eliminating the v-band style mount, the piston and its venting ports can sit much lower, which reduces the overall height to a number others can’t match.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eIn the race to create the most compact and highest flowing blow-off valve, GFB’s SV52 pulls ahead of the pack.\u003c\/p\u003e\n\u003cp\u003e300PSI boost and standing only 86mm tall (including the weld-on adapter), the SV52 is 10mm shorter than the nearest competitor, AND flows more!\u003c\/p\u003e\n\u003cp\u003eWinner of the 2020 SEMA Global Media award.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"LA Fabrication UK","offers":[{"title":"Default Title","offer_id":57250670969157,"sku":null,"price":259.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0883\/1293\/8821\/files\/7366c0_0de7c8412a22474ab78c356e3c5e525b_mv2.jpg?v=1772062808"}],"url":"https:\/\/lafabrication.uk\/collections\/gfb.oembed","provider":"LA Fabrication UK","version":"1.0","type":"link"}
