The body and bonnet castings are made in a T\u00dcV certified foundry. The valves can be serviced in-line without dismantling the piping. Horizontal connection, vertical connection type FT44V (flow direction from top to bottom). FT44 uses BP99\/32 liquid bladder and can be applied to superheated steam with superheat degree of 150\u2103@0 bar g,50\u2103@32 bar g. The valve can be used with a BP99\/32 liquid bladder.<\/p>\n<h3>(an official) standard<\/h3>\n<p>This product complies with the European Pressure Equipment Directive 97\/23\/EC and is available with marking on request.<\/p>\n<h3>options (as in computer software settings)<\/h3>\n<p>Manually adjustable needle valve (model FT44-C) for use with horizontally connected FT44's only. This option also offers a steam lock breaking function (SLR), consult Spirax Sarco for more information. If required, 3\/8\" BSP or NPT tapped holes can be drilled in the top of the bonnet for a counterbalance pipe or 3\/8\" BSP or NPT tapped holes can be drilled in the bottom of the bonnet for a drain valve, to be specified at time of order.<\/p>\n<h3>Certification<\/h3>\n<p>This product can be supplied with EN10204 3.1 certificate.
