The Betts Wet-R-Dri Valve is a lightweight and compact quarter turn in-line stop valve. This easily maintained and versatile valve is widely used for liquid, gaseous or dry products and is available in a variety of sizes.  This valve comes with an actuator that opens and closes the valve and provides a visual indicator that clearly shows the orientation of the valve disc.  The actuator is available in various styles:

  • air-open/air-close ASA (model “37”)
  • air-open/spring-close ASA (model “39”)
  • spring-open/air-close ASA (model “39” with suffix “017”)
  • hydraulic-open/spring-closed ASA (model “38”)
  • spring-open/hydraulic close ASA (model “38” with suffix “017”)

The body is offered in aluminum, cast iron or stainless-lined with coatings available for increased chemical resistance and extended service life.  The actuator is e-coated aluminum with a robust fiberglass cylinder.  The disc seal and shaft O-rings are available in a variety of materials to optimize chemical resistance and service temperature range.  Valve mounts between 125# or 150# ASA/ANSI flanges.

Installation: The Wet-R-Dri Valve may be mounted in any position.  Care should be taken when mounting valve to be sure the I.D. of adjoining flanges or pipe is large enough to allow the disc of the valve to open freely.  Valve mounts between 125# or 150# ASA/ANSI flanges.
