Features
- Wafer style cast iron monoblock for high strength
- Stainless steel stem
- Rapid flow through the bottom of the valve during operation causes solids to be flushed from the body cavity ensuring the full stroke of the valve
- Knife blade of stainless steel, polished on both sides and machined to an edge to cut perfectly through the fluid
- Valve seal in highly resistant, long-lasting EPDM sleeves in permanent contact with each other, ensuring full bore flow
- No seat cavities to cause material build-up and no fluid contact with metallic parts
