Paint Supply System

We independently research and develop a full range of fluid control products with precision engineering and intelligent manufacturing. Our spray accessory systems deeply integrate core technologies such as pumping, filtration, agitation, metering, pressure regulation, proportioning, and automatic color change. Supported by high-performance fluid pipelines and connectors, they form a precise, stable, and efficient fluid control hub.

Types of Paint Supply System

HT-PRV 3.0 Paint Pressure Regulator

The Paint Pressure Regulator (Pressure Relief/Stabilizing Valve) is a specialized pressure control device in coating systems, installed at the paint pump outlet to stabilize fluid delivery pressure, mitigate pulsation fluctuations, and ensure consistent spray flow for enhanced coating quality.

INQUIRY Detail

HT-BPRV 3.0 Back Pressure Regulator

The back pressure regulator is a critical device in spray systems for precise fluid pressure control. It is typically installed in paint circulation pipelines or at the pump return line to maintain stable system pressure, prevent paint backflow, eliminate air bubbles, and ensure uniformity of spray atomization.

INQUIRY Detail

HT-ARP Flow Control Valve

Pneumatic Pressure Regulator is specifically designed for automated spraying systems. Featuring a compact structure, it can be directly mounted on robot wrists or near spray guns to achieve precise and rapid fluid pressure control.

INQUIRY Detail

HT-Filter Paint Filter Machine

Paint filters are key components in coating systems designed to purify paints by effectively removing impurities, particles, and gels, ensuring stable spraying quality. They can be used to filter paints and other fluids.

INQUIRY Detail

5 Gallon Paint Agitator/Paint Mixer

Paint Agitator is a key equipment in the coating production line, designed for mixing and homogenizing paints to ensure consistent viscosity and uniform pigment distribution, thereby maintaining stable coating quality. It is suitable for stirring various solvent-based, water-based, and high-viscosity paints.

INQUIRY Detail

15 Gallon Paint Agitator/Paint Mixer

INQUIRY Detail

HT-HPS Upper Suction Paint Supply Units

This system is specifically designed for automated spraying lines, utilizing vacuum suction and circulating paint delivery technology to transfer coatings directly from storage containers to spray guns or robotic atomizers. It ensures stable paint supply, bubble-free operation, and prevents sedimentation.

INQUIRY Detail

Lower Suction Liftable Paint Supply System

This system is an intelligent paint delivery solution designed for automated spraying production lines, utilizing bottom suction technology to pump coatings directly from storage containers to spray guns or robotic atomizers, ensuring stable, efficient, and contamination-free paint supply. It is suitable for high-precision coating applications in automotive, electronics, furniture, and other industries.

INQUIRY Detail

Centralized Paint Supply Unit

The Centralized Paint Feeding System (CPFS) is a high-efficiency, intelligent paint circulation solution designed to deliver coatings from a central supply station to multiple spraying points. This modular system integrates paint agitator, pumping, filtration, pressure regulation, and return flow control, ensuring stable, uniform, and efficient paint delivery while significantly improving coating quality and production efficiency.
