Jet Valve Seals are core precision sealing accessories for various high-speed jet dispensing valves, pneumatic jet valves and piezoelectric jet valves, as well as key components to ensure the stable operation of non-contact jet dispensing systems. Widely compatible with automatic jet dispensers, high-speed micro glue spraying equipment, high-frequency fluid jet valves and other automatic precision dispensing equipment, they stabilize the sealing performance during valve pressurization, glue storage, high-frequency jetting and instantaneous glue cutoff, and effectively solve industrial problems such as air leakage, glue leakage, pressure cross-flow, glue hanging and jet accuracy deviation in precision jetting processes.

Jet valves work under harsh conditions including high-frequency opening and closing, high-speed fluid scouring, instantaneous pressure switching and long-term medium soaking, which put forward extremely high requirements on the rebound speed, dimensional accuracy, fatigue resistance and medium resistance of seals. This series of Jet Valve Seals are precisely made of modified fluororubber, imported PTFE composite materials and high-temperature resistant wear-resistant elastic materials.

Adopting micron-level precision machining, mirror polishing and anti-stick & anti-corrosion strengthening treatment, they possess excellent properties such as low compression deformation, high resilience, high-frequency fatigue resistance, glue swelling resistance and acid & alkali corrosion resistance. With accurate dimensions and high fitting degree, the seals perfectly adapt to the micro-stroke, high-speed jetting and instantaneous start-stop characteristics of jet valves, maintaining stable sealing performance during long-term continuous mass production.

Featuring strong compatibility, the seals are suitable for various high and low viscosity industrial fluids such as UV glue, flux, epoxy resin, AB glue, silica gel, hot melt adhesive, ink and lubricating oil. They thoroughly eliminate valve micro-leakage, unstable air pressure, jet divergence, glue trailing and valve jamming. With complete specifications compatible with most mainstream domestic and imported jet valve models and support for non-standard precision customization, the seals meet the requirements of 24-hour uninterrupted high-speed jetting on assembly lines, effectively improving dispensing consistency and product yield, and reducing equipment maintenance frequency and consumable replacement costs.

• High-frequency Fatigue Resistance & Long-term Sealing: Developed for the high-frequency reciprocating opening and closing working conditions of jet valves, the material features fast rebound speed and excellent toughness, avoiding relaxation, deformation and aging during long-term high-speed operation to maintain durable sealing performance.
• Micron-level Precision Fitting: Adopting integrated precision molding technology with minimal dimensional error, it fits the valve body mating surface seamlessly, eliminating micro air leakage and micro glue leakage and stabilizing the internal pressure of the equipment.
• Medium Resistance & Anti-swelling Performance: Compatible with various precision industrial glues and chemical fluids, it resists corrosion and swelling without residual glue adhesion, preventing sealing failure and valve blockage caused by medium erosion.
• Strong Adaptability to High-speed Working Conditions: With fast response speed, it fits and seals synchronously with the high-frequency movement of the valve body without jamming or lagging, perfectly adapting to high-speed non-contact jet dispensing processes.
• Clean Glue Cutoff & High Accuracy: Uniform and stable sealing performance ensures constant glue output pressure, concentrated jetting without divergence, and clean cutoff without trailing or hanging glue, accurately controlling the quality of micro-volume dispensing.
• Cost Reduction & Easy Maintenance: Effectively reduce equipment downtime, dispensing defects and glue waste, lower the comprehensive cost of equipment cleaning, maintenance and consumable replacement, and adapt to long-term mass production.
