Red Valves Self-Clean

Condensed Catalog - 19323 Sleeve Trim Selection

The pinch valve sleeve’s flexingaction breaks away any solid ordewatered slurry buildup. The fullround port sleeve has no pocketsfor slurry to plug or erode.

Standard Sleeves,

provided by Red Valve, are veryspecialized components. Great care is taken to match the type of elastomer, pressure rating and tempera- ture limits to the customer’s needs. This insures a long and maintenance-free service life. The full port of the standard sleeve provides uninterrupted flow, just like another piece of pipe, and the flow remains stream- lined when throttled. Standard Sleeve

Cone Sleeves,

patented by Red Valve, are designedfor control applications. Cone sleeves provide tighter control with a 20:1 turndown ratio and 0.89 pressure recovery factor, along with an extra thickness of elastomer on the downstream side of the cone to increase its service life.

Double-Wall Sleeves

are designed for extremelyabrasive slurries. The Double-Wall Sleeve has triple the thickness of elastomer than the Standard Sleeve. The next larger valve size must be used with the Double Wall to maintain a full port due to the additional thickness of the sleeve. Cone Sleeve*

Cone sleeve trim provides tightercontrol with a 20:1 turndown ratioand 0.89 recovery factor. Pressurerecovery occurs downstream of thesleeve, so cone sleeves can handlea higher pressure drop than othersleeve designs. Double-Wall Sleeve
