  • Rotary Valve Cavity Air Purge

    Smoot offers the cavity air purge process on its entire line of rotary valves to reduce abrasion on the rotor, cylinder, and endplates. This patented design uses low-pressure air from the convey blowers and purges the material from the cavity between the shroud and the housing plates. This air...

  • Rhino Rotary Valve

    The Rhino rotary "R" valve is designed for continuous discharge of dry, free-flowing, low-abrasive solids in gravity flow or low-pressure systems. This rotary airlock valve is equipped with neoprene rubber-tipped rotor vanes, ensuring a superior seal and cost-efficient maintenance over...

  • Series K Easy Clean Slide Gates

    The Series K easy clean slide gate is for applications where frequent cleaning is required. The easy clean slide gate allows easy and quick disassembly without tools. Constructed from 304 stainless steel with UHMW pressure plates, they are available in sizes from 2 to 8 in. with tube stub...

  • Rotary Airlock Valves

    Drop Through (DT) and Blow Through (BT) rotary airlock valves are designed for sanitary pneumatic convey systems operating within -15 in. Hg to +15 PSIG with 6- to 12-in.-capacity options. The standard nine-blade rotor positions two blades to always be in contact with the discharge side of the...

  • Self-Cleaning Rotary Valve

    A second rotor has been added to the PMV modular rotary valve to give it self-cleaning capability. The second rotor of the PMDS double rotor modular rotary valve is synchronized and gear-driven to scrape the primary rotor clean on each revolution. The double rotor valve is precisely engineered in...

  • Containment Butterfly Split Valve

    Available in 4-, 6-, 8-, and 10-in. sizes, the containment butterfly split valve achieved a level of <.2 µg/cu m during its OEL test with SMEPAC, and can operate at 45 PSI. Although both active and passive valves are made of 316L stainless steel, they are extremely lightweight and easy to...
