NexTech E Series Trunnion Ball Valve
Brand: ValvTechnologiesOrder up a safer, higher-performing side-entry valve that is both tough and multi-functional.
The NexTech® E Series (enhanced series) represents a true engineered-to-spec, specialty valve with materials selected to meet the needs of the most demanding applications.
These valves are designed and configured to handle corrosive, high-temperature and high-solid applications requiring zero-leakage shutoff.
ValvTechnologies’ NexTech® valves offer safety and reliability in a wide variety of pressure-critical applications.
Features- Live-loaded gland area - The NexTech® design features a four stud, live-loaded assembly designed for heavy industrial applications. The sealing material is high purity Grafoil® surrounded by stainless steel wire mesh anti-extrusion rings.
- Carbide sealing surfaces - The sealing surfaces are overlaid with tungsten or chromium carbide using our exclusive HVOF RiTech® process. These surfaces have a hardness of 68 – 72 Rc to allow long periods of operation in the most severe conditions.
- High integrity seat surfaces - To prevent leaks around the seats, ValvTechnologies has developed an innovative double seal design for high temperature operation and/or high cycling applications. In low temperature, high cycling service, a secondary elastomer seal is installed on the seat perimeter
- Solids resistance - In addition to the carbide coatings which will allow the valve to function in highly abrasive applications, the individual valve parts have additional seals to prevent interference from solids in the system. This provides for outstanding performance in catalyst systems, streams with solids contamination and polymers.
