-
“Sanspar C.I Double Door, Chrome Plated Doors 301C Check Valves” — likely means the product from Sanspar (they are a South African supplier of valves) SANSPAR

“C.I” = Cast Iron → body is cast iron

“Double Door” = dual plate/dual disc check valve style
-
“Chrome Plated Doors” = the two plates (doors) are chrome plated (for additional corrosion/cavitation resistance)
-
“301C” = model or part code, perhaps a particular size, pressure rating or special specification within Sanspar’s catalogue
-
Low head‐loss / minimal pressure drop: Because the dual plates open widely and the profile is wafer style, flow resistance tends to be lower. lzdongsheng.en.made-in-china.com+1
-
Quick closure to prevent backflow: The spring-assisted or gravity assisted plates close rapidly when flow reverses, helping reduce water hammer. Energy Valves+1
-
Space saving & light weight: Wafer style reduces overall weight and simplifies installation compared to full flanged bodies. lzdongsheng.en.made-in-china.com

Versatile installation: Many models allow horizontal or vertical installation (flow upwards) depending on design
