Kursi Katup Stainless Steel minangka komponen sealing presisi sing nyedhiyakake permukaan kawin kritis kanggo cakram utawa bal katup, njamin shutoff positif lan nyegah aliran balik ing sistem pipa. Kursi tutup kudu nolak erosi, karat, karusakan cavitation, lan galling nalika njaga stabilitas dimensi ing fluktuasi tekanan lan suhu. Rampung lumahing ing antarmuka panyegelan langsung nyebabake kenceng bocor lan urip siklus katup.
Ningbo Ruican ngasilake kursi tutup tutup stainless steel nggunakake proses casting investasi sol silika, ngasilake kursi kanthi kualitas permukaan sing apik, ketebalan tembok sing konsisten, lan profil internal sing kompleks. Metode casting investasi utamané cocog kanggo wesi tahan karat kayata CF8M (316 stainless), CF3M (316L stainless), lan duplex gelar stainless, kang angel kanggo mesin saka stock bar ngalangi lan rawan kanggo hardening karya.
Sawise casting, saben jog tutup tliti CNC machined lan lapped kanggo entuk flatness lumahing sealing dibutuhake lan roughness lumahing. Kapabilitas lapping in-house kita entuk flatness permukaan sealing ing 2 pita cahya (0.0005 mm), njamin shutoff kenceng gelembung saben standar pengujian API 598 lan MSS-SP-61. Kita nglayani produsen katup, kontraktor EPC pipa, lan pemasok sistem cairan industri ing saindenging jagad.
