Metered Valve with Viscosity Adaptation for Industrial Glue Coating Machines with Anti-Drip

Optimized for industrial glue coating machines handling hot melt glue and acrylic glue, our Metered Valve adapts to diverse glue viscosities while preventing drips. The valve's viscosity adaptation (500-10,000 cP) via a variable-speed core ensures smooth flow—critical for high-viscosity hot melt glue (8,000 cP at 180℃) and low-viscosity acrylic glue (500 cP). Its anti-drip design with spring-loaded seal closes instantly after coating, eliminating glue waste and coating defects such as drips on packaging.

With precise flow control (0.5-20mL/min, ±0.4% error), it matches coating widths from 5-500mm for various applications including cartons and electronics. Crafted from heat-resistant PPS plastic (maximum 200℃), it supports temperature control to maintain glue fluidity. Compatible with pneumatic coating systems, it features quick-disconnect functionality for easy glue type switching.
