Pinch Valve Sleeves
Red Valve has been manufacturing pinch sleeves longer than any other company in the world!
Red Valve Pinch Valve Sleeves are designed specifically for low maintenance and are able to outlast conventional metal valves because of their superior elastomer technology. Our Pinch Valve Sleeves are constructed much like a heavy-duty truck tire, with bias-ply, fabric-reinforced rubber providing the structural support. The sleeves are the only wetted part of the valve, eliminating the need for valve bodies made of expensive metal alloys. Because the sleeves are the only wetted part, they are the only replacement part needed in pinch valves. There are never any seats, packing, seals or bellows to replace.
-
Unmatched Elastomer Technology.
-
Designed specifically for low maintenance.
-
The full-port design is ideal for slurry and solids handling.
-
In throttling applications, sleeves maintain a laminar flow for better control with less cavitation.
-
When abrasive particles strike the elastomer surface of Red Valve Pinch Valve Sleeves, the impact is absorbed and then deflected back into the particle. This resiliency allows our Pinch Valve Sleeves to wear at a much slower rate than metals or even ceramic surfaces.
Each Red Valve Pinch Valve Sleeve is backed by our unmatched elastomer technology, knowledge and manufacturing expertise. We incorporate only the latest and best technology in elastomer compounding and synthetic materials, resulting in the world’s most durable and accurate Pinch Valve Sleeves that outperform and outlast all others.
The most important part of any pinch valve is its elastomer sleeve. The sleeve is truly the "heart" of the pinch valve, providing corrosion and abrasion resistance and pressure containment. The quality of any pinch valve is only as good as the quality of its sleeve. When you specify a Red Valve Pinch Valve, you can be confident knowing the internal elastomer sleeve is superior in design, construction, durability and performance.

Cone Sleeves, patented by Red Valve, are designed for 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.
-
Standard Sleeves, manufactured by Red Valve, are very specialized components. Great care is taken to match the type of elastomer, pressure rating and temperature limits to the customer’s needs. This ensures 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 streamlined when throttled.
-
Double Wall Sleeves are designed for extremely abrasive slurries. The Double Wall Sleeve has triple the thickness of elastomer than a 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.
-
High Pressure Sleeves are designed for high pressure ANSI 300 applications up to 720 psi. The High Pressure Sleeve features stronger fabric reinforcement and thicker construction compared to a Standard Sleeve. The face flanges are equipped with integrated o-ring seals to ensure a tight seal under high pressure applications.
