System Valves and Accessories

The Importance of Valves and Accessories for Plastics Conveying Systems

No selection of Plastics Auxiliary Equipment for Plastics Conveying Systems is complete without a wide array of valves and accessories to complement the Plastics Auxiliary Machinery.The list might include things like Machine Hoppers or Machine Bins which mount on machine throats. Other things that are likely included are Vacuum Purge valves, Proportioning Valves, External Line Valves, Discharge Selection Valves,  Vacuum Takeoff Boxes, Closed Loop Relief Valves, Station T Sequencing Valves and External Line Valves.

These Plastics Conveying System Accessories all serve valuable purposes within systems used for conveying plastics pneumatically.

EPV External Proportioning Valve

Inlet/Outlet O.D. 1.5” - 4” (3.9 - 100 mm)

Product Description

External proportioning valves are used as a material line selector at the receiver inlet, typically in regrind proportioning applications. The EPV can also be used for purging material lines to prevent build-up and plugging of the material lines.

    Features:

    • Durable Construction
    • Easy-View of Interior
    • Easy Access
    • High Temperature Applications

Machine Hopper Assemblies

8 to 38 lb. (3.6 to-18.8 kg) Capacity

Product Description

These multi-purpose hoppers can be mounted on feeder machine adapters or directly on machine throats.

    Features:

    • Clear View of Material Level
    • Loader-Ready Lid
    • Clean-Out Door
    • Feed Throat Adapter
    • Discharge Slide Gate
