Key Features & Operational Advantages
- Precise Flow Control with Electro-Pneumatic Positioner
The integrated YT-1000 Positioner converts a 4–20mA electrical control signal directly into precise pneumatic force, allowing automated control loops to adjust valve opening percentages with extreme accuracy and minimal hysteresis.
- Complete Fluid Isolation for Corrosive Applications
Designed to prevent fugitive emissions and body wall erosion, the internal elastomeric/fluoropolymer diaphragm acts as a dynamic seal. This isolates working components from harsh acids, alkalis, slurries, and viscous media.
- Extended Finned Bonnet for Thermal Management
The body neck features cooling fins that dissipate heat, protecting actuator seals, stem packing, and positioner electronics during high-temperature fluid handling.
- Built for Demanding Industrial Environments
Manufactured in accordance with ISO 9001:2015 quality standards, Flowbiz control valves feature flanged Class 150 end connections for secure, leak-free installation into standard industrial pipelines.
Common Applications
- Chemical & Petrochemical Processing: Control of aggressive acids, caustics, organic solvents, and corrosive byproducts.
