{"product_id":"olymberyl-olive-spin-valve","title":"Olymberyl Olive Spin Valve","description":"\u003cp\u003eThe spin valve on the Olymberyl Olive is a circular rotating disc fitted in the stove door that controls primary air intake into the firebox. Turning it open or closed lets you regulate heat output and burn rate. Over time the disc can seize, warp, or lose its tension, making accurate air control difficult.\u003c\/p\u003e\n\n\u003cp\u003e✅ \u003cstrong\u003eCompatible with:\u003c\/strong\u003e Olymberyl Olive HFB243B\u003c\/p\u003e\n\n\u003cp\u003e🔧 \u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWeight: 0.33 kg\u003c\/li\u003e\n\u003cli\u003eMaterial: Cast iron\u003c\/li\u003e\n\u003cli\u003eHeat resistance: 650°C\u003c\/li\u003e\n\u003cli\u003ePart number: HFB243-20\u003c\/li\u003e\n\u003cli\u003ePart type: Spin valve \/ primary air control\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGood primary air control is key to burning efficiently and safely.
