Side-Entry Rotary Valve Airlock

Protect Fragile Materials | Reduce Product Loss | Maximize Product Quality

Precision Machine & Manufacturing’s Side-Entry Rotary Valve Airlock is purpose-built for fragile, lightweight, or brittle materials. Unlike top-entry valves that shear and compress during entry, this innovative side-inlet design allows material to gently enter rotor pockets—minimizing breakage, dust generation, and product loss.

Perfect for applications in food processing, animal feed, plastics, ceramics, and specialty chemicals, the PMM side-entry valve protects product integrity while maintaining precise metering and efficient airlock function.

Key Features:

  • NFPA-Upgradeable: Configurable to meet NFPA 69 & 85 compliance if/when needed.

  • Side-Entry Inlet: Reduces impact, shear, and turbulence

  • Product Integrity: Preserves shape, density, and value of delicate materials

  • Abrasion-Resistant Construction: U.S.-sourced steel for long wear life

  • Tight Rotor Clearances: Improves sealing and feed consistency
