Why Choose Our Rotary Valve?

Built Tough

Carbon steel construction with powder-coated finish stands up to demanding industrial environments

Easy to Service

Simple grease points and accessible wear parts mean less downtime and lower maintenance costs

Flexible Setup

Flanged design with multiple configuration options to suit your specific application

What It Does

The Telford Smith Rotary Valve controls material discharge from cyclones, hoppers, and bulk bags into pneumatic conveying systems.

Common Applications:

✓ Cyclone discharge systems

✓ Bulk bag discharge into conveying lines

✓ Controlled dosing of free-flowing materials

✓ Positive to negative pressure transfer

Handles: Pellets, granules, and flakes up to 20mm particle size

How It Works

Material enters through the 350mm × 350mm flanged inlet and fills the rotating 6-chamber rotor. As the rotor turns at speeds up to 57 RPM, chambers carry material from inlet to outlet for controlled discharge.

Key Features:

• Rubber or urethane rotor tip seals maintain chamber separation
• Optional Variable Speed Drive (VSD) for precise feed rate control
• Designed for positive-to-negative pressure applications

Frequently Asked Questions

Q: What's the difference between the TSE.RV and TSE.RV.VSD models?

A: The TSE.RV has a fixed speed motor for consistent flow applications, while the TSE.RV.VSD includes a Variable Speed Drive for adjustable feed rates when you need process flexibility.

Q: Can the rotary valve handle powders?

A: No, our rotary valve is designed for free-flowing pellets, granules, and flakes up to 20mm. It is not suitable for powders due to tolerance design.

Q: How quickly can I get spare parts?

A: As an Australian manufacturer, we typically supply spare parts within 1-2 days, compared to weeks for imported alternatives.

Q: What's the typical throughput?

A: Maximum theoretical volume is 73 m³/hr at 57 RPM. Actual throughput in kg/hr depends on your material's bulk density. Contact us for application-specific calculations.

Q: Can you customize the inlet/outlet configuration?

A: Yes, we offer custom adaptors including square-to-square, square-to-round, and other flange configurations to suit your existing system.
