NVS AISI 316 Stainless Steel Mini Ball Valve (Female-Female)
NVS AISI 316 Stainless Steel Mini Ball Valve (Female-Female)
NVS AISI 316 stainless steel mini ball valve: BSP female thread on both ends (ISO 228), hex body. Size range: ¼″–¾″ (4 sizes). This small-bore ball valve has a short hex-profile body that fits into tight spaces; it opens and closes with a quarter turn of the lever and connects with female threads on both ends.
AISI 316 (1.4401) is a molybdenum-alloyed stainless steel. It resists chloride media, sea water and chemicals significantly better than grade 304 and is recommended for swimming pools, coastal sites, chemical plants and outdoor use.
Applications
- Pressure gauge and sampling lines
- Pump, filter and instrument inlets
- Small-diameter water, air and food lines
- Boiler and heating equipment connections

Selection and installation notes
- Use PTFE tape or a thread sealant; do not over-tighten stainless threads, as this can cause galling (cold welding).
- This is an on/off valve; do not use it for throttling in a partly open position.
- Grade 316 contains molybdenum and resists chloride media and sea water better than 304.
- Direct contact between stainless steel and galvanized or carbon steel can cause galvanic corrosion; use insulation (washers, unions) between different metals.
