To meet industry demands for durability and leak-free performance, all Weidmann radiator valves undergo 100% leak testing using a highly accurate hydrogen tracer gas method to ensure maximum reliability. In North America, Weidmann valves are offered in weld-on or bolt-on designs compatible with 3-inch and 4-inch diameter radiators.<\/p>\n\n\n\n<h4 class=\"wp-block-cite-wordpress-theme-heading has-mb-sm has-md-font-size\" id=\"precision-manufacturing-and-testing\">Precision Manufacturing and Testing<\/h4>\n\n\n\n<p>Weidmann radiator valves for power transformers are machined in conjunction with UBW in the United States using state-of-the-art equipment. Valves are produced and 100% tested under an ISO certified Quality Management System. A computer-monitored mass flow testing process is used, with testing accuracy maintained, pass\/fail, at a 0.1 CC\/minute leak rate limit, which calibrates to zero observable leakage for transformer applications.<\/p>\n\n\n\n<h4 class=\"wp-block-cite-wordpress-theme-heading has-mb-sm has-md-font-size\" id=\"benefits-of-radiator-valves-for-power-transformers\">Benefits of Radiator Valves for Power Transformers<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>By controlling the flow of transformer oil from the transformer tank to radiators or heat exchangers, radiator valves help <a>to increase the loading<\/a> capacity of the transformer.<\/li>\n\n\n\n<li>Radiator valves offer utilities the ability to remove radiators easily from transformers for the purposes of repair, maintenance, or replacement.<\/li>\n\n\n\n<li><a>Radiator valves allow for radiators to be installed on transformers at their final destination.<\/a><br><br><\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-cite-wordpress-theme-heading has-mb-sm has-md-font-size\" id=\"product-summary\">Product Summary<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Provides ease of assembly and installation.<\/li>\n\n\n\n<li>Offers optimum product support with rapid deployment of corrective actions or assistance when required.<\/li>\n\n\n\n<li>Manufactured with <a>a high level<\/a> of precision in an ISO certified facility<a>.\u00a0<\/a><\/li>\n\n\n\n<li>Tight tolerances, continuous <a>measuring<\/a>, and thorough testing throughout the manufacturing process guarantee uniformity of dimensions for reliable installation.<\/li>\n\n\n\n<li>Weidmann valves undergo 100% testing before being shipped to ensure a leak-free design.<\/li>\n\n\n\n<li>Weidmann offers in-house valve design services, custom testing, and engineering services.<\/li>\n\n\n\n<li>Valves, accessories, replacement parts, and local warehousing are available in the United States, Mexico, and Canada.<br><\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Radiator valves are essential components in oil-immersed power transformers.
