Print this page.

The Betts Wet-R-Dri Valve is a lightweight and compact ¼ 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.  The manual detent model provides a positive stop in the open and closed position as well as a detent spring and ball which assist in holding the disc in the open or closed position. The body is offered in aluminum, cast iron or stainless-lined with coatings available for increased chemical resistance and extended service life.  The disc seal and shaft O-rings are available in a variety of materials to optimize chemical resistance and service temperature.  Bolt pattern matches TTMA piping flange dimensions.

Installation: The Wet-R-Dri Valve may be mounted in any position with handle located for easy operation.  Standard right-hand operation, opens by turning handle ¼ turn counterclockwise and left-hand operation (clockwise opening) is available for valve with suffix “032”. 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.  It is recommended to use Betts flanges and adapters shown in Section 50, Page 5A.
