DSS Valves

R2S & S2S Valves

R2S & S2S stands for Round-to-Square and Square-to-Square Valves, respectively. Well, that’s what we call them. You might also hear them referred to as junk trap, trash extractor, reject, or scavenger valves. Either way, the DSS iteration will provide you with the innovative Guided Shear Gate Design for tough applications found in high-density cleaners (cyclones) and pneumatic conveying processes. These valves were built to separate the waste from the valuable material in all forms of pulp manufacture and re-manufacture.

The key to the Guided Shear Gate design is the shearing tip and internal gate guides. From open to close the gate is fully guided, which removes any chance of deflection due to media. The end result? A knife gate valve capable of bi-directional zero leakage in Class 150 pressures that can shear through metal, fiber and anything else found in these severe service applications.
