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\u003e\nFor 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\u003e\nBy 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\u003ch4\u003ePatent Pending\u003c\/h4\u003e","brand":"GFB","offers":[{"title":"Default Title","offer_id":49106136662134,"sku":"T9052","price":359.1,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2414\/8083\/files\/gfb-t9052-gallery-1.jpg?v=1792714294","url":"https:\/\/empireperformance.com.au\/products\/gfb-t9052","provider":"Empire Performance","version":"1.0","type":"link"}
