If an application requires the valve to modulate clean fluid, there are several designs that will provide both tight shut-off and control. However, when the media contains solids (i.e. slurry), there is no perfect valve. The designs typically chosen to modulate slurry will provide tight shut-off when brand new, but often leak shortly after being in service.
SlurryFlo control valves provide Class IV shut-off when new and well into their service life. The unique metal-to-metal seating surface overlaps to maintain Class IV, even after substantial wear. A Class IV shut-off isolates 99.99% of the flow.
SlurryFlo manufactures a full range of ANSI 600 control valves for higher pressure applications (rated to 1480 PSI working pressure). Please consult SlurryFlo if dimensional specifications are required.
SlurryFlo holds Canada wide CRN's for all control valve designs, sizes and pressure classes.
