Professional FAQ: Key Terms & Technical Inquiries
1. What does "JIS 5K 25A" actually stand for?
"JIS" refers to Japanese Industrial Standards; "5K" indicates the pressure class (5 kgf/cm² ≈ 0.5 MPa); "25A" is the nominal pipe size (1 inch/25mm diameter).
2. What are the standard body materials for JIS 5K 25A Wafer-Type Ball Valve?
The main standards include CF8M (304L/316 Stainless) and WCB (Carbon Steel), both complying with ASTM A351/A216; providing excellent corrosion/strength balance.
3. What is meant by "Wafer-type"?
"Wafer-type" denotes the compact, sandwich construction fitting between two flanges, saving space and weight compared to lug or double-flanged ball valves.
4. How does "Class VI Leakage" benefit industrial flows?
Class VI (ISO 5208/ANSI FCI 70-2) certifies bubble-tight shutoff (leakage <0.15 ml/hr/inch), minimizing product loss and eliminating fugitive emissions — critical for chemical and water facilities.
5. What is the operational life expectancy of these valves?
Under typical use, the JIS 5K 25A Wafer-Type Ball Valve surpasses 50,000 cycles at max pressure-temperature, with 8+ years in continuous industrial lines (third-party tested per ISO 5208).
6. What standards govern test and quality?
Essential standards include: ISO 5208 (leakage), JIS B2002 (design), FDA CFR21 (seat/contact), EN 12266 (pressure test), and ISO 9001:2015 (process).
7. How is installation handled, and are there actuator options?
Installation is via wafer-mount between standard flanges; direct-mount ISO 5211 pad for pneumatic/electric actuators, lever, or gear box (automated control upgrades available).
