PVDF Butterfly Valve (Gear) - 100% Virgin Grade PVDF
Heavy-Duty Flow Control for Corrosive & High-Temperature Systems
PVDF Butterfly Valve (Gear Operated) is a robust thermoplastic valve designed for precise flow regulation and reliable shut-off in large-diameter and high-pressure piping systems. Manufactured from premium-grade Polyvinylidene Fluoride (PVDF), this valve provides outstanding chemical resistance, superior thermal stability, and long operational life.
The gear-operated mechanism (worm gear operator) ensures smooth, controlled operation with reduced manual effort—especially ideal for bigger valve sizes and higher torque requirements.
At ASK Innocomp, we supply precision-engineered PVDF Gear Operated Butterfly Valves suitable for chemical plants, pharmaceutical facilities, semiconductor industries, and ultra-pure water systems.
