{"id":292,"count":4,"description":"Ventilation valves control how fresh air is supplied and how stale air is extracted in each room. They are essential for balancing your ventilation or MVHR system, helping you achieve the right airflow rates while keeping noise levels comfortable.\r\n\r\nIn this category you\u2019ll find supply and extract valves for different room types and airflow needs. The right valve choice and correct adjustment improve air distribution, reduce drafts, and make the system easier to fine-tune during commissioning or maintenance.\r\n\r\nUse this category when you\u2019re finishing a new installation, replacing old valves, or upgrading for better airflow control and a cleaner look.","link":"https:\/\/wtwstore.com\/sverige\/product-category\/valves-grilles\/valves","name":"Ventiler","slug":"valves","taxonomy":"product_cat","parent":291,"meta":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.0 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Valves | WTW Store<\/title>\n<meta name=\"description\" content=\"Ventilation valves for MVHR systems: supply and extract valves for balanced airflow, low noise and comfort.
