HAXGSV0001 is specifically for millivolt, natural gas configurations — installing the wrong valve type can create a serious safety hazard. Always have a licensed technician perform the replacement and leak-test the gas connections after installation.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-18 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54303478677779,"sku":"HAXGSV0001","price":582.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-gas-valve-for-universal-h-series-150-400-btu-natural-gas-heaters-haxgsv0001-2.webp?v=1790071820","url":"https:\/\/poolaroo.com\/products\/hayward_haxgsv0001","provider":"Poolaroo","version":"1.0","type":"link"}
