Introduction: Why Sorter Valve Selection Matters

In modern optical sorting systems, the sorter valve is the core execution component that determines sorting accuracy, air consumption efficiency, system stability, and material purity rate.

Even with advanced AI and camera systems, improper valve selection can reduce overall performance significantly. That is why correct sorter valve selection is critical.

Material-Based Sorter Valve Selection

Rice Sorter Valve (High Frequency Application)

Rice sorting systems require ultra-high frequency operation and extremely fast response time.

Key Requirements

• Ultra-fast response time

• Low inertia design

• Short and precise air pulse

• Stable high-frequency operation

Rice is lightweight, so even millisecond-level delay can affect sorting accuracy.

Recommended: High-frequency rice sorter valve with fast response and low power consumption design.

Plastic Sorter Valve (Medium Flow Application)

Plastic sorting is widely used in PET, HDPE, and mixed plastic recycling industries.

Key Requirements

• Medium airflow capacity

• Stable continuous operation

• Balanced response speed

• Anti-clogging structure

Plastic materials require stronger airflow than rice but still need controlled precision.

Recommended: Balanced plastic sorter valve with stable medium flow output.

Mineral Sorter Valve (High Flow Application)

Mineral sorting systems operate in harsh mining environments requiring strong air impact force.

Key Requirements

• High airflow capacity

• Strong impact force

• Dust and heat resistance

• Long service life

Minerals are heavy and require powerful air pulses for effective separation.

Recommended: High-flow heavy-duty mineral sorting valve.

Key Technical Factors in Sorter Valve Selection

1. Flow Rate

Flow rate determines air output strength. Higher flow means stronger separation force.

• Rice → Low/medium flow

• Plastic → Medium flow

• Mineral → High flow

2. Response Time

Response time affects how fast the valve reacts to signals.

• Rice → Ultra-fast

• Plastic → Medium

• Mineral → Fast but stable

3. Blowing Time

Blowing time controls air pulse duration.

• Rice → Short pulse

• Plastic → Medium pulse

• Mineral → Long pulse

FAQ – Sorter Valve Selection

What is a sorter valve used for?

A sorter valve is used in optical sorting systems to eject unwanted materials using compressed air pulses.

What is the difference between rice and mineral sorter valves?

Rice valves focus on high frequency and fast response, while mineral valves focus on high flow and strong impact force.

Can one valve be used for all materials?

No. Different materials require different airflow and response characteristics.
