{"id":291,"count":0,"description":"Valves and grilles are the visible end points of a ventilation or MVHR system. They distribute fresh air into rooms and extract used air, helping you balance airflow, comfort and noise levels in everyday use.\r\n\r\nIn this category you\u2019ll find supply and extract valves, door grilles for air transfer between rooms, and pressure relief grilles to manage overpressure. Choosing the right valve or grille improves air distribution and makes the system easier to tune, whether it\u2019s for a new installation or a replacement.\r\n\r\nUse this category to find the correct finishing components for each room and ensure your ventilation system works efficiently and comfortably.","link":"https:\/\/wtwstore.com\/belgie\/product-category\/valves-grilles","name":"Ventielen &amp;
