The CVS Series EW valve bodies are single port, globestyle bodies with cage guiding, clamped seat rings and pushdowntoclose valve plug action.
This series features large end connections and expanded internal flow cavities. The series is available 8 x 6, 10 x 8, 12 x 6 and 12 x 8inch sizes. The first number refers to the line size, and the second refers to the trim and bonnet size.
There are three body configurations in this design series:
1. Design EWD is intended for general control applications over a wide variety of temperatures and pressure drops. This design has balanced valve plug with metaltometal seating.
2. Design EWS is intended for applications requiring better shutoff capabilities than those suitable for the EWD. This valve uses an unbalanced valve plug with metaltometal seating, or optional metaltoTFE seating.
3. Design EWT is suitable for applications with stringent shutoff requirements. This valve uses a balanced valve plug with metaltoTFE seating, or metaltometal seating for use in higher temperatures.
