Compact Gravity-Feed Male Paint Spray Valve for Portable Touch-Up Kits with Viscosity-Adapting Fluid Control and Drip-Free Shutoff
Product Description
Designed for maintenance crews and field technicians, this ultra-compact male paint spray valve enables professional finishes in confined spaces. Weighing just 140g, its gravity-feed design works flawlessly with handheld touch-up guns for equipment repairs, structural touch-ups, and spot refinishing. The innovative viscosity-sensing regulator automatically adjusts fluid pressure from 50-1,000 cP – equally effective with thin lacquers or thick enamels. A positive-action shutoff mechanism provides instant drip-free stopping, critical when working on vertical surfaces. The 360° rotatable fluid cup allows spraying at any angle, while the stainless steel filter screen (100 mesh) traps particulates that cause nozzle clogs. Perfect for shipboard maintenance, bridge repairs, and factory equipment servicing, this valve operates at 15-40 PSI using standard air compressors. Its all-weather seals perform from -20°C to 80°C, making it indispensable for infrastructure and agricultural maintenance teams.
Bullet Points

FAQ:
Q: What’s the minimum compressor CFM required?
A: Our touch-up gun valve operates efficiently at 3 CFM @ 25 PSI.
Q: How does the viscosity regulator work?
A: The viscosity-sensing regulator uses spring-loaded discs that modulate flow based on paint resistance.
Q: Can I use this valve with 2K paints?
A: Yes with optional static-dissipative kit to prevent ignition hazards.
Q: What maintenance does the filter screen need?
A: The removable filter screen cleans in solvent - replace annually with heavy use.
Q: Is the fluid cup chemical-resistant?
A: Yes, PP fluid cup withstands ketones, acetates, and alkyds.
