Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang NDS dari 3G Electric.
What are the pressure and temperature ratings for NDS PVC ball valves?
NDS manual two-way PVC ball valves are rated to a maximum pressure of 150 psi (CWP). The operating temperature range for these valves is typically from 14°F to 140°F, as specified for the swing check valves in the same material. For precise temperature limits, refer to the specific model's datasheet.
What connection types are available for NDS swing check valves?
NDS swing check valves are available with IPS x IPS (iron pipe size) or FIP x FIP (female iron pipe) connections. These are inline valve body configurations, allowing for direct installation in PVC piping systems. Sizes range from 3/4 inch to 2 inch.
Are NDS PVC ball valves suitable for potable water applications?
NDS PVC ball valves are made from PVC material, which is commonly used in potable water systems when certified to NSF/ANSI 61 or similar standards. However, you should verify the specific model's certifications for potable water use, as not all PVC valves are automatically approved for drinking water.
What is the flow rate capacity of NDS swing check valves?
NDS swing check valves have specified flow rates depending on size. For example, the 1-inch model (MPN 1520-10) has a flow rate of 20.2 gpm, while the 2-inch model (MPN 1520-20F) has a flow rate of 78.44 gpm. These values are based on standard conditions and may vary with system pressure and piping layout.
Can NDS PVC ball valves be used with threaded or socket connections?
Yes, NDS PVC ball valves are available with both FNPT x FNPT (female national pipe thread) and Socket x Socket connections. The FNPT versions allow for threaded installation, while socket connections require solvent welding. Both types are rated to 150 psi (CWP) and come in sizes from 1/2 inch to 1 1/2 inch.
