These valves were built to separate the waste from the valuable material in all forms of pulp manufacture and re-manufacture. Whether you refer to them as junk trap, trash extractor, reject or scavenger valves, our DSS Severe Service Knife Gate Valves can be applied to the toughest applications found in high-density cleaners (cyclones) and pneumatic conveying processes. Round-to-Square, Square-to-Square and standard round port options are available, all featuring a Guided Shear Gate.

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 bidirectional zero-leakage in Class 150 pressures that can shear through metal, fiber and anything else found in these severe service applications.
