Available in 3\/8&#8243;, 1\/2&#8243;, 3\/4&#8243; and 1&#8243; NPT connections, all the internal parts are stainless steel for long service life.<\/p>\n<p>The Tunstall Thermal-Disc\u2122 operates using Bernoulli\u2019s Theorem; as condensate enters the Thermal-Disc\u2122 Trap, it lifts the thermal disc and discharges through outlet ports. Multiple outlet ports assure that the lift of the disc is parallel to the seat for efficient operation. Once the condensate reaches its flash point, the pressure on the top of the disc increases, due to higher velocity steam, causing the disc to snap closed. As the steam above the disc condenses, pressure above the disc will lower, and allow the disc to lift again and repeat the process.<\/div>\n<h3 class=\"collapseomatic \" id=\"id65f828a71bdd2\"  tabindex=\"0\" title=\"Features\"    >Features<\/h3><div id=\"target-id65f828a71bdd2\" class=\"collapseomatic_content \">\n<ul>\n<li>In-Line Connection<\/li>\n<li>Integral Strainer<\/li>\n<li>Compact Size<\/li>\n<li>High Strength Stainless Steel Construction<\/li>\n<li>Low Maintenance (Only one moving part)<\/li>\n<li>Can be installed Vertically for &#8220;Freeze Proof&#8221; installation<\/li>\n<\/ul>\n<\/div>\n<h3 class=\"collapseomatic \" id=\"id65f828a71be43\"  tabindex=\"0\" title=\"Applications\"    >Applications<\/h3><div id=\"target-id65f828a71be43\" class=\"collapseomatic_content \">\n<ul>\n<li>Steam Main Drainage<\/li>\n<li>High Pressure Drips<\/li>\n<li>Tracer Lines<\/li>\n<li>Process Equipment<\/li>\n<li>Laundry Equipment<\/li>\n<li>Kitchen Equipment<\/li>\n<li>Superheated Steam applications<\/li>\n<li>Outdoor installations subject to freezing<\/li>\n<\/ul>\n<\/div>\n<h3 class=\"collapseomatic \" id=\"id65f828a71be97\"  tabindex=\"0\" title=\"Construction\"    >Construction<\/h3><div id=\"target-id65f828a71be97\" class=\"collapseomatic_content \">\n<table border=\"1\" cellspacing=\"0\" cellpadding=\"3\" align=\"center\">\n<tbody>\n<tr>\n<td colspan=\"2\" bgcolor=\"#cbd7ed\"><strong>Materials of Construction<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Body<\/td>\n<td>Stainless Steel Casting ASTM A743<\/td>\n<\/tr>\n<tr>\n<td>Cap<\/td>\n<td>Stainless Steel AISI 420<\/td>\n<\/tr>\n<tr>\n<td>Disc<\/td>\n<td>Stainless Steel AISI 420<\/td>\n<\/tr>\n<tr>\n<td>Strainer Screen<\/td>\n<td>Stainless Steel AISI 420<\/td>\n<\/tr>\n<tr>\n<td>Strainer Cap<\/td>\n<td>Stainless Steel AISI 420<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h3 class=\"collapseomatic \" id=\"id65f828a71beed\"  tabindex=\"0\" title=\"Specifications\"    >Specifications<\/h3><div id=\"target-id65f828a71beed\" class=\"collapseomatic_content \">\n<strong>Pressure\/Temperature Rating<\/strong><br \/>\nPMA &#8211; Max.

A 20 mesh strainer is recommended upstream of the trap as is an isolation valve. Piping to and from the trap should be equal to the trap connection (one size larger is acceptable). Body material is not suitable for welding.<\/p>\n<p>Freeze proof installation is achieved by installing the trap vertically, discharging downward. All drains must be pitched towards the trap. Discharge piping must be self-draining.<\/p>\n<\/div>\n<p><strong>BULLETIN: <a href=\"https:\/\/www.dropbox.com\/s\/q4lw7iz49l3zjyw\/Bulletin-TA-Series-TA-TD-0814.pdf?dl=1\" Target=\"_blank\">Series-TA-TD-0814 &#8211; Thermal-Disc<sup>\u2122<\/sup> Steam Traps &#8211; Series TA-TD<\/strong><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>BULLETIN: Series-TA-TD-0814 &#8211; Thermal-Disc\u2122 Steam Traps &#8211; Series TA-TD<\/p>\n","protected":false},"author":8,"featured_media":0,"parent":73,"menu_order":3,"comment_status":"closed","ping_status":"open","template":"","meta":{"footnotes":"","_links_to":"","_links_to_target":""},"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/tunstall-inc.com\/wp-json\/wp\/v2\/pages\/119"}],"collection":[{"href":"https:\/\/tunstall-inc.com\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/tunstall-inc.com\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/tunstall-inc.com\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/tunstall-inc.com\/wp-json\/wp\/v2\/comments?post=119"}],"version-history":[{"count":1,"href":"https:\/\/tunstall-inc.com\/wp-json\/wp\/v2\/pages\/119\/revisions"}],"predecessor-version":[{"id":86088,"href":"https:\/\/tunstall-inc.com\/wp-json\/wp\/v2\/pages\/119\/revisions\/86088"}],"up":[{"embeddable":true,"href":"https:\/\/tunstall-inc.com\/wp-json\/wp\/v2\/pages\/73"}],"wp:attachment":[{"href":"https:\/\/tunstall-inc.com\/wp-json\/wp\/v2\/media?parent=119"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
