The M81 is a pared down version of our Severe Service Knife Gate Valve, providing a lighter offering perfect for applications that still require bi-directional zero leakage isolation, but only up to MSS-SP-81 pressure specifications.
The Severe Service Through Gate Valves (SSTGVs) provide true zero leakage to this traditional valve design. Originally designed for the pulp & paper industry for high density pulp stock, the SSTGV suits a variety of unique applications.
The DSS SSCKV is the premier Check Valve on the market today and is engineered to perform where conventional Check Valves fail.

Sometimes it takes two Severe Service Valves to get the job done right. By combining these two valves, the SSKGV adds the additional assurance of zero leakage isolation when closed.
TIVs provide zero-leakage isolation in Pulp and Paper, Oil and Gas, Mining, and Chemical applications.
Built for severe service control applications, including high solids slurry control, our Control Valves resist wear from the erosion and abrasion that these aggressive applications present.
See how our SSKGV and Soft Start Paste Valves take on one of the toughest applications — Paste Backfill.
Also known as junk trap, trash extractor, reject or scavenger valves, the Round-to Square and Square-to-Square Valves can be used in the toughest applications.
The DSS Torque-Tek Actuation Gun is a powerful accessory that works with all DSS Knife Gate Valves with handwheels or gear operators.
DSS Valves are helping mining and mineral processing organizations improve their ESG scores, reduce material waste, and achieve the lowest cost of ownership — all while protecting the environment and staff.
