DSS Transmitter Isolation Valve (TIV)
Zero Leakage Isolation for Tank Transmitters.
DSS Transmitter Isolation Valves (TIVs) provide zero leakage isolation and troublefree operation that ensures worker safety when instrumentation is being calibrated, maintained or replaced.
These valves are great options for Pulp & Paper, Oil & Gas, Mining and Chemical applications because of their ability to cut through material in the pipeline, form a tight seal under high and low pressure, and resist corrosive substances.

Work. With no limitations.
North American made Severe Service Double Block and Bleed Valves.

Built specifically for your applications.
We’ve utilized the same ground-breaking technology from our SSKGV design to create Transmitters Isolation Valves that provide zero leakage isolation and have the ability to shear through solids without fail.
Our products are known for their ability to handle differential pressure scenarios, corrosive materials, extreme temperatures and detrimental solids in a variety of applications.
Product Features
The DSS Severe Service Knife Gate Valve is designed to solve problems in the harshest of conditions. With our customers in mind we’ve carefully crafted this valve to overcome common problems like pipe turbulence and erosion, leakage to atmoshere, pipe stress, and topworks structure failures without compromising our promise to true isolation.

Actuation Options
Our Severe Service Knife 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.
