Features & Benefits
Full Bore Unobstructed Flow
Open sleeve provides flow path equal to pipe ID with no metal parts, crevices, or obstructions to trap solids or scale.
Only Rubber Sleeve Wetted
All metallic body parts are isolated from process fluid by the sleeve, eliminating corrosion, erosion, and product contamination.
Low Air Consumption
Sleeve collapse requires only 4-6 bar air; no large actuator volume or high-pressure air supply needed.
Self-Cleaning Sleeve Collapse
Sleeve collapse action flexes the rubber surface, dislodging scale and crystalline deposits with every cycle.
Replaceable Sleeve
Sleeve can be replaced in minutes by removing end plates, without removing valve from piping or disturbing flange joints.
