Professional FAQ: Mini Ball Valve 1/8
- Q1: What is the maximum pressure for mini ball valve 1 8?
- A1: Standard models are rated up to PN63 (913 psi / 63 bar). Always confirm with supplier datasheet for your selected material and thread type.
- Q2: What is the difference between “Full Port” and “Reduced Port” for 1 8 npt mini ball valve?
- A2: Full Port means the internal bore equals the pipe I.D., offering minimal flow restriction (Cv up to 1.2), while Reduced Port features a smaller bore, trading a slight flow loss for overall compactness.
- Q3: Which material is best for highly corrosive fluids?
- A3: For acids, brine, or chlorinated media, choose 316 stainless steel body with PTFE seat—confirmed by ISO 15156 corrosion testing for oil & gas service.
- Q4: What Standards govern 1 8 npt mini ball valve threads and testing?
- A4: Threads: ANSI/ASME B1.20.1 NPT
Testing: ISO 5208 for seat leakage, ANSI/ASME B16.34 for pressure integrity. - Q5: What is a typical lifespan of these valves?
- A5: Life-cycle tests indicate >50,000 cycles under qualified fluids and regular handling; as per manufacturer’s in-house QA and ISO/TR 11365 guidelines.
- Q6: Are there fire-safe and anti-static versions available?
- A6: Yes, by special order. These variants comply with API 607 (Fire-Safe Design) and include anti-static devices for ignition-prone environments.
- Q7: How is mini ball valve 1 8 installed?
- A7: Using pipe wrench with suitable thread sealant (PTFE tape or anaerobic paste), torque as per ANSI table, always ensure parallel alignment to avoid seal wear and thread galling.
