Bellow Seal and Gland Seal Control & Shut Off Valves
Advanced dual-sealed control and shut-off valves delivering absolute zero fugitive emissions for hazardous, toxic, and high-temperature critical process applications.
Advanced Bellow Seal & Gland Seal Valve Solutions
Engineered for maximum operational safety and zero fugitive emissions, our bellow seal and gland seal valves feature a dual sealing protection system. Combining a multi-ply metallic bellows seal with a secondary gland seal, these valves eliminate stem leakage, making them ideal for handling toxic, corrosive, flammable, and high-temperature fluids like thermal oil and steam. Covering sizes from 1/2" to 12" and pressure ratings up to ANSI Class 1500, they provide precise flow control and reliable shut-off. Fully automation compatible, they are available with manual, pneumatic, and electric actuation for seamless integration into chemical, petrochemical, power, and pharmaceutical process systems.
