Pneumatic & Hydraulic Operated 12″ Wet-R-Dri Butterfly Valve (non-TTMA)
The Betts 12” Wet-R-Dri Valve is a quarter turn in-line stop valve that is comparatively lightweight and compact for its large thru area. This easily maintained and versatile valve is widely used for liquid, gaseous or dry products. 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
- Air-open/spring-close
- Hydraulic-open/spring-closed
The body is offered in aluminum or aluminum with stainless liner. Body coatings are available for increased chemical resistance and extended service life. Grease fittings come standard for drive shaft and bearing shaft. 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.
- Air cylinder max pressure = 150 psig (10 bar)
- Hydraulic cylinder max pressure = 3,000 psig (207 bar)
- Actuator max temperature 240°F (116°C)
