  • Material Transfer Using Valves and Retractable Sleeves

    June 5, 2012

    In continuous processing material transfer methods are typically fixed operations, with mechanical and pneumatic conveying covering most applications. However batch processing of powders presents its own unique challenges especially under those circumstances where containment is critical such as...

  • Drop Through and Blow Through Rotary Airlock Valves

    June 5, 2012

    These rotary air lock valves are designed for sanitary pneumatic conveying 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 housing providing a superior seal...

  • Patent-Pending Seal

    June 4, 2012

    With the EZ Seal, your Plattco double flap airlock valve will provide you with a bubble tight seal and prevent any air leakage. Unlike traditional rotary airlocks, the double flap valve with EZ seal technology provides a positive airlock seal, virtually eliminates excessive leakage and the cost of...

  • Rotary Airlocks

    May 31, 2012

    Horizon offers a range of rotary airlocks from light-duty service to a USDA-approved easy clean rotary airlock. With its Airlock Rebuild Program, the company can rebuild an old airlock to look and run like new for 25% less than the cost of a new one. Several styles of diverter valves are available...

  • Rotary Airlock Valves

    May 30, 2012

    Carolina Conveying offers three types of heavy-duty rotary airlocks: Drop Thru, Blow Thru, and Side Entry. All units come standard with regreasable bearings, helical gearboxes, predrilled body vents, and predrilled air purge connections. These valves are rated up to 20 psi pressure differentials,...

  • Tool-less, CIP Rotary Airlock Valve for Sanitary Applications

    May 29, 2012

    Designed specifically for sanitary applications, such as food processing or pharmaceutical processing, the Quick-Clean Series of rotary airlock valves aids in regulatory standards and practices compliance, reduces cleaning and sanitizing time, and simplifies inspection. This line of ACS cast...

  • Self-Cleaning Rotary Valves

    May 25, 2012

    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 valve is synchronized and gear-driven to scrape clean the rounded pockets on the primary rotor on each revolution. As with the company’s other rotary...

  • Cone Valve

    May 24, 2012

    The cone valve is used in conjunction with the charging hopper as the main inlet and sealing valve for the conveying system. The charging hopper’s design eliminates head pressure, and vents the displaced air when material fills the pressure vessel, thus allowing the single cone valve to...

  • Light-Duty Aerolock Rotary Valve

    May 22, 2012

    The K-Tron Light-Duty (LD) Aerolock rotary valve is engineered for low-pressure or low-vacuum service applications. The LD Aerolock is ideally suited for use with fine powders and dusts commonly associated with cyclone or filter-type dust collectors where a head of material does not build up on top...

  • Slide Diverter Valve

    May 21, 2012

    The three-position slide diverter valve features a sealing method that uses regulated compressed air, applied to the sealing rings. This results in an airtight seal between the inlet and outlet ports and allows the valve to can be used in either pressure or vacuum pneumatic conveying systems. This...
