CETO 2-PC Full Bore Ball Valve SS304 CF8 Spesifikasi & Perbandingan
Kata Kunci Utama: CETO 2-PC ball valve SS304, full bore ball valve, ball valve CF8 Kata Kunci Turunan: 1-PC vs 2-PC vs 3-PC ball valve, full bore vs reduced bore, SS304 ball valve, ball valve JIS 10K, ball valve untuk oil gas chemical
CETO 2-PC Full Bore Ball Valve SS304 Quick On/Off untuk Industri
2-PC ball valve adalah sweet spot antara cost dan serviceability — lebih mudah maintenance dari 1-PC, lebih ekonomis dari 3-PC. CETO 2-PC Full Bore Ball Valve SS304 dengan full bore design memberikan zero pressure drop + smooth flow — cocok untuk oil & gas, chemical, palm oil, water treatment.
Spesifikasi Teknis
1-PC vs 2-PC vs 3-PC Ball Valve Kapan Pilih Mana?
Buyer sering bingung: 1-piece, 2-piece, atau 3-piece? Berikut comparison:
Kapan Pilih 2-PC Ball Valve?
Size DN 15 – DN 100 (½" – 4")
Butuh maintenance access (bisa clean seat/ball, ganti seal)
Flanged connection (JIS 10K, PN16)
Budget moderate lebih mahal dari 1-PC tapi jauh lebih murah dari 3-PC
Industrial applications (oil & gas, chemical, water treatment)
Kesimpulan: 2-PC adalah pilihan terbaik untuk kebanyakan aplikasi industrial.
Full Bore vs Reduced Bore Apa Bedanya?
CETO 2-PC ini adalah full bore — apa artinya?
Example
DN 50 (2") Full Bore:
Ball ID: 50mm (sama dengan pipa)
Pressure drop: ~0 psi
DN 50 Reduced Bore:
Ball ID: ~38mm (setara DN 40)
Pressure drop: ~1–2 psi
Kapan Pilih Full Bore?
High flow rate critical
Pressure drop harus minimal
Pigging operations (pipeline cleaning)
Viscous fluids (crude oil, slurry)
Kesimpulan: Full bore = zero restriction — ideal untuk high-flow applications.

FAQ Pertanyaan Umum
Q: Apa perbedaan 1-PC, 2-PC, dan 3-PC ball valve?
A: 1-PC: body one-piece (tidak bisa buka, throw-away saat rusak) — paling murah. 2-PC: body 2 bagian (bisa buka untuk clean/repair seat/ball) — sweet spot. 3-PC: body 3 bagian (bisa lepas full assembly tanpa uninstall) — paling mudah maintenance tapi paling mahal. Untuk industrial, 2-PC recommended.
Q: Apa itu full bore ball valve?
A: Full bore = ball ID sama dengan pipe ID (no restriction). Reduced bore = ball ID lebih kecil (~1 size). Full bore memberikan zero pressure drop dan bisa pigging — ideal untuk high-flow applications. Trade-off: sedikit lebih mahal dan lebih berat.
Q: Apakah ball valve cocok untuk throttling?
A: TIDAK recommended. Ball valve dirancang untuk on/off (fully open atau fully closed). Throttling di partial open (30–70°) bisa cause: (1) seat erosion, (2) cavitation, (3) vibration. Untuk throttling, pakai globe valve atau butterfly valve.
Q: Berapa umur pakai PTFE seat ball valve?
A: Tergantung cycle frequency dan media. On/off occasional: 10–15 tahun. Frequent cycling (daily): 5–7 tahun. Abrasive media: 3–5 tahun. Ganti seat kalau: (1) leaking, (2) handle berat, (3) visual damage.
Q: Apakah SS304 cocok untuk seawater?
A: Tidak cocok untuk long-term seawater — chloride attack bisa cause pitting corrosion. Untuk seawater, upgrade ke SS316 (molybdenum content lebih tinggi, better chloride resistance).
Q: Bagaimana cara maintenance 2-PC ball valve?
A: Quarterly: visual inspect (leaks, handle operation). Annually: (1) isolate & drain, (2) unbolt body, (3) remove ball & seats, (4) clean all parts, (5) inspect wear/damage, (6) ganti seals, (7) re-assemble dengan new gasket, (8) pressure test. 2-PC advantage: bisa maintenance tanpa uninstall valve dari pipa.
