NVS AISI 316 Stainless Steel Ball Valve (Flanged, 3-Piece)
NVS AISI 316 Stainless Steel Ball Valve (Flanged, 3-Piece)
NVS AISI 316 stainless steel 3-piece flanged ball valve: flanged on both ends, 3-piece body. Size range: ½″–4″ (9 sizes). This ball valve has a three-piece body with flanges on both ends; because the body parts can be separated, the ball and seals can be replaced during maintenance.
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
- Medium-diameter process pipelines
- Food, beverage and dairy plants
- Water, air and heating lines
- Chemical and industrial lines that require maintenance

Selection and installation notes
- The bolt circle and number of holes of the mating flange must match the line flange; check the bolt circle diameter in the size table.
- The ball and seals can be replaced by removing the body bolts; release the line pressure before maintenance.
- 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.
