Industrial Chemical Plant Valve Control EAC Certification TISSIN TS600 TS700 TS800 TS900 Valve Positioners

The Tissin TS700Ex is the explosion-proof version of the proven TS700 series, specifically engineered for Zone 1 & 2 (Class I Div 1) hazardous locations. Certified Ex d IIC T6 Gb (ATEX/IECEx/KCs), it retains all the performance advantages of the standard model — ±0.5% accuracy, high air capacity (350 LPM exhaust), and external zero/span adjustment — while providing maximum safety in flammable atmospheres. Ideal for offshore platforms, refineries, LNG terminals, and hydrogen plants where pure pneumatic operation is preferred for ultimate reliability.
