TVC/SST General Service Ball Valves

TVC/SST's versatile, general service valve is designed to meet the most demanding critical service application. Every part has been designed to meet the brutal demands of critical isolating processes through computerized design software. While the general service valve is the most intricate product in the TVC/SST line, it is also the most flexible, meeting the demands of any isolation service. TVC/SST General Service Ball Valves range from 0.50 inches to 24 inches and can be built to a wide array of materials for bodies and trim. Optional features include bi-directional flow, dual solids excluders, coatings and shut-off classes up to Class VI (bubble tight).

General Applications and Configurations

TVC/SST Signature (Fugitive Emission) Ball Valves

The Signature Fugitive Emission Ball Valve incorporates the latest breakthrough technology from TVC/SST. The patented, Triple Redundant Sealing Stem design was developed for use in lethal gas applications where safety and performance are critical. The elongated packing box eliminates the possibility of leakage. TVC/SST Signature Fugitive Emission Ball Valves range from 1/2" to 24" and can be built to a wide array of materials for bodies and trim. Optional features include bi-directional flow, dual solids excluders, coatings and shut-off classes up to Class VI (bubble tight).
