http://www.china-yfm.com/Uploads/Products/p_show2015519174047.jpg Medical viewports are products that have been independently developed to meet the requirements of medical applications, taking into account the conditions in those environments. The valve body is fabricated through integral silica sol casting, while the lining material is made of sanitary-grade PFA. The interior of the valve features a dovetail groove structure, which enhances the adhesion of the lining, allowing it to function properly even under vacuum conditions. Structural features: ▪ Valve body cast from silica sol, with a structure to prevent material accumulation. ▪Valve body lining is made of sanitary-grade PFA. ▪ The valve body features a dovetail groove design to prevent vacuum formation.
