GLOBTOS pre-insulated valves are an advanced system solution, guaranteeing the highest energy efficiency for your network and trouble-free operation in district heating pipelines laid directly in the ground.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><br><strong><strong>GLOBTOS Pre-insulated Valves: Performance in Trenchless Systems<\/strong><\/strong><\/h2>\n\n\n\n<p>Our pre-insulated steel ball valves are designed for operation in the most demanding conditions. Thanks to factory-applied thermal insulation, the on-site installation process is significantly shortened, and the integrity of the system remains intact for decades.<\/p>\n\n\n\n<p>As a manufacturer, we focus on parameters that have a real impact on the thermal balance of your investment:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Insulation:<\/strong> Rigid polyurethane foam (PUR) with high thermal insulation properties.<\/li>\n\n\n\n<li><strong>Casing:<\/strong> Outer jacket made from high-density polyethylene (HDPE), resistant to moisture and electrochemical corrosion.<\/li>\n\n\n\n<li><strong>Tightness:<\/strong> Full compliance with EN 488 and leakage Class A in accordance with EN 12266-1.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><br><strong><strong>The Innovative &#8220;Dry Stem&#8221; \u2013 Safety and Protection Against Failures<\/strong><\/strong><\/h2>\n\n\n\n<p>We fully understand that pipeline projects require flexibility. We offer the manufacture of pre-insulated valves to order, where the stem height (dimension L) is precisely tailored to the installation depth of the pipeline.<\/p>\n\n\n\n<p><strong>Why is the dry stem technology beneficial for your network?<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Impact protection:<\/strong> Even in the event of mechanical damage or bending of the stem (e.g. by an excavator bucket), the valve remains leak-tight. The medium does not escape to the outside, eliminating the risk of emergency network shutdowns.<\/li>\n\n\n\n<li><strong>Adaptability:<\/strong> Because the stem is dry, it can be safely shortened or extended directly on the construction site, adjusting it to the ground elevation levels.<\/li>\n\n\n\n<li><strong>Mechanism durability:<\/strong> The stem has no contact with district heating water chemistry, which prevents corrosion and scale build-up.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\"><br><strong><strong>Customisation: Pre-insulated Valves with Non-standard Stem Height (Dimension L)<\/strong><\/strong><\/h2>\n\n\n\n<p><br>We fully understand that pipeline projects require flexibility.
