1. Inspeksi Pra-instalasi: Konfirmasi kompatibilitas bahan katup kanthi medium cairan, suhu, lan tekanan. Priksa pasuryan pungkasan GB Standard Stainless Steel Gate Valve kanggo goresan. Priksa manawa bahan gasket cocog karo syarat panggunaan lan konfirmasi manawa baut / kacang memenuhi syarat kekuatan.
2. Instalasi Alignment: Aja meksa Alignment. Misalignment bisa nyebabake deformasi kursi katup, bocor, utawa stres struktural. Ndhukung pipa kanthi mandiri ing cedhak tutup. Kencengake bolt kanthi bertahap kanthi urutan sing bentuke lintang nganti entuk torsi seragam. Sawise sistem wis mlaku sajrone 24-48 jam, kenceng maneh baut.
3. Prosedur Operasi: Katup Gerbang Stainless Steel Standar GB kualitas dhuwur kudu mbukak utawa ditutup kanthi lengkap-bukaan sebagean bakal nyepetake erosi kursi / piring katup kanthi cairan kacepetan dhuwur. Operate mung nggunakake handwheel; ora tau nggunakake kunci / tuas. Batang tutup kudu dilumuri saben seprapat.
4. Testing lan Maintenance: Sawise instalasi, sadurunge sistem commissioning, test meksa statis kudu dileksanakake ing GB Standard Stainless Steel Gate Valve ing 1,5 kaping PN dirating meksa. Sajrone tes, katup kudu diisolasi saka peralatan hilir.
5.Storage lan Penanganan: Katup kudu disimpen ing jero ruangan lan dilindhungi saka kelembapan. Sadurunge instalasi, tutup mburi kudu tetep ing posisi sing diinstal.
1. The GB Standard Stainless Steel Gate Valve digawe saka stainless steel austenitic, kang wis resistance banget kanggo korosi saka oxidizing media asam.
2. Nalika medium mili liwat GB Standard Stainless Steel Gate Valve, arah aliran tetep panggah, asil ing resistance adi kurang.
3. Arah gerakan gapura tegak lurus karo arah aliran medium, nyebabake torsi mbukak lan nutup sing kurang lan operasi tanpa usaha.
4. Arah aliran medium ora diwatesi, tanpa ngganggu aliran cairan utawa nyuda tekanan. Media kasebut bisa mili saka salah siji sisih tutup gerbang, entuk tujuan sing dituju. Iku utamané cocok kanggo pipelines ngendi arah aliran medium kang bisa ngganti.
5. The GB Standard Stainless Steel Gate Valve dipasang vertikal ing awak tutup, asil ing dawa struktural cendhak.
6. The GB Standard Stainless Steel Gate Valve nduweni kinerja sealing apik. Nyandhang ing permukaan sealing minimal nalika mbukak kanthi lengkap.
