The Mark EW valve bodies are single port, globe-style bodies with cage guiding, clamped seat rings and push-down-to-close valve plug action. Providing excellent pressure and flow control on steam, gasses, and various liquid processes.
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 8, 16 x 12, 20 x 16, 24 x 16, and 24 x 20-inch 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:
The Mark EWD Series is intended for general control applications over a wide variety of temperatures and pressure drops. This design has balanced valve plug with metal-to-metal seating.
The Mark EWS Series is intended for applications requiring better shutoff capabilities than those suitable for the EWD. This valve uses an unbalanced valve plug with metal-to-metal seating, or optional metal-to-TFE seating.
The Mark EWT Series is suitable for applications with stringent shutoff requirements. This valve uses a balanced valve plug with metal-to-TFE seating, or metal-to-metal seating for use in higher temperatures.
