DESIGN FEATURES
1. Full Port
2. UNI - Directional Flow
3. Less Pressure Drop
4. Better Corrosion Resistance than steel & alloys
5. The liner is locked by grooves permitted the check valve to be used on high vaccum & pressure applications without line collapse and blow out.
6. These valves often out-perform expensive exotic alloy valves as they economically handle corrosive or High - Purity Flow Media
7. External Body is coated with corrosive resistant paint.
8. All Lined Portion are spark Tested to 10,000V.
