DSS Severe Service Through Gate Valve (SSTGV)
Zero Leakage Isolation for Unique Applications
DSS Valves is breathing new life into the traditional Through Gate Valve by combining it with our technologically advanced Guided Shear Gate Design. The end result is a Severe Service Through Gate Valve (SSTGV) with true zero leakage, bi-directional performance.
The SSTGV displaces media into its port while closing, and releases it back into the stream when in an open position. This makes the Through Gate a perfect solution to static columns and applications with large amounts of solids in the pipe.


Severe service performance, specialized applications
Originally designed for the pulp & paper industry for high density pulp stock, the SSTGV suits a variety of unique applications such as:
- blast furnace dust catcher
- electric arc furnace dust
- flue gas
- static columns
Product Features
The DSS Severe Service Through Gate Valve is packed with all the standard tech you would find in our traditional SSKGV offering. Most important in this design is the dual transverse sealing system, energized bore ring, and internal primary and secondary seals that eliminate fugitive emissions.

Actuation Options
Our Severe Service Through Gate Valves are compatible with a wide range of actuation options.
We’re always happy to tailor the valve actuation to suit your needs. We’ll find you a solution, whether that means low profile arrangements, stem extensions or gear operators on pneumatic, hydraulic, electric or electro-hydraulic systems.
