Application scenarios
Silo Discharge Control for Bulk Solid Materials
Installed at silo discharge outlets or connecting pipe sections for dry bulk solids such as granules and powders to control material flow. The valve is not suitable for liquid or gaseous media; the non-fully-sealing design of the body and disc helps preserve material integrity and reduce particle jamming.
Tank Truck Loading/Unloading Interfaces for Bulk Solid Materials
Installed at tank truck loading/unloading pipelines or flange connections for transporting bulk solids to control the material path. The product features a wafer-type connection, supports the EN 1092 tank truck flange standard, with nominal diameters from DN 80 to DN 300 and a maximum operating pressure of 6 bar.
Dry Powder and Granular Raw Material Conveying Lines in Food Applications
Installed in conveying and feeding lines for dry powder, granules, or other non-liquid raw materials in food production to control material flow. All media-contacting parts are corrosion-resistant and FDA-approved, and the product is not suitable for liquid or gaseous media.
Selection points
Non-Fully Sealing Design for Non-Liquid/Gas Media
The body and disc are not fully sealed, and a chamber-free design is used to preserve material integrity; the valve is not suitable for liquid or gaseous media.
Tank Truck Flange Connection Compatibility
The connecting flange complies with the EN 1092 tank truck flange standard and can be adapted to PN 6/10/16 according to customer requirements.
One-Piece O-Ring Flange Face Seal
The valve seals the flange face by means of a one-piece O-ring, compatible with EN 1092 Form A/B or ASME RF flange sealing faces.
Corrosion-Resistant, FDA-Approved Media-Contacting Parts
All parts in contact with the medium are corrosion-resistant and FDA-approved.
Triple Bushings and One-Piece Precision-Slotted Shaft
The valve features triple bushings and a one-piece precision-slotted shaft, listed as a maintenance-free design feature.
FAQ
Which media is the EBRO TW-M wafer butterfly valve suitable for?
The TW-M is not suitable for liquid or gaseous media and is better suited to applications where material integrity must be preserved. Its body and disc are not fully sealed, and the chamber-free design helps prevent stagnant spaces from forming inside the valve.
What are the features of the sealing design of the TW-M butterfly valve?
The valve seals the flange face by means of a one-piece O-ring. The body and disc feature a non-fully-sealing design to meet the requirement of preserving material integrity.
How to select the size, pressure rating, and flange connection of the TW-M?
The TW-M is available in nominal diameters from DN 80 to DN 300 with a maximum operating pressure of 6 bar. The connecting flange follows the EN 1092 tank truck flange standard; pressure ratings can be PN 6, PN 10, or PN 16 as required, and the flange sealing face can match EN 1092 Form A/B or ASME RF. Selection should be confirmed based on pipe diameter, flange specifications, and actual operating pressure.
Is the TW-M convenient for actuator installation and field layout?
The TW-M complies with the EN ISO 5211 top flange standard, making it easy to match the corresponding valve actuator connections; the valve can be installed in any position, offering high flexibility in field layout.
What hygienic and corrosion-resistant properties do the media-contacting parts of the TW-M have?
All parts in contact with the medium are corrosion-resistant and FDA-approved. The valve also features triple bushings and a one-piece precision-slotted shaft, and is designated as a maintenance-free design.
