High-Precision, Flame-Proof Valve Control for Hazardous Environments
The Tissin TS900 Smart Valve Positioner is engineered for demanding industrial applications where safety, reliability, and precision are paramount. Designed as a flame-proof / explosion-proof device, it meets Ex d IIC T5/T6 standards, making it ideal for oil & gas, petrochemical, power generation, and chemical plants operating in hazardous zones.
With its robust construction, modular design, and advanced control features, the TS900 ensures accurate valve positioning, predictive maintenance capabilities, and long-term operational stability, even under extreme environmental conditions.
Explosion-Proof Safety: Certified to Ex d IIC T5/T6 standards, ensuring safe operation in flammable or high-risk environments.
Precise Valve Control: Supports both linear (10–150 mm) and rotary (0–90°) actuators with high accuracy.
Smart Automation Features: Includes auto-calibration, Partial Stroke Test (PST), self-diagnostics, and alarm notifications to minimize downtime and improve reliability.
Flexible Operation: LCD + 4-button interface allows easy local configuration, while the auto/manual switch enables manual override for maintenance.
Durable Construction: Aluminum die-cast body with optional SS316, rugged IP66/NEMA 4X enclosure resists dust, water, vibration, and impact.
Efficient Performance: High-flow pilot valve ensures fast actuation, while low air consumption (<2.3 LPM) and over 100 LPM flow capacity deliver efficient operation.
Wide Temperature Range: Operates from –30°C to 85°C (standard) and –40°C to 85°C (low-temp version), with explosion temperature ratings from –40°C to 60°C depending on T-class.
