Everlasting Valve’s BMV Series is built for dirty, high-cycling bulk-material applications where knife gates, ball valves, pinch valves, flappers, and other conventional designs can plug, leak, erode, or require constant repair.

Shop ProductBMV Series valves use Everlasting’s rotating-disc technology, open-body configuration, and shearing action to help keep abrasive solids moving while protecting the sealing surfaces.
| Common field problem | Why it happens | EV BMV solution |
|---|---|---|
| Valve will not close against chunks or packed material | Ash, clinker, or granular solids can lodge across the sealing area. | Rotating disc and seat edges shear particulate from the sealing path during cycling. |
| Seat erosion and leakage | Abrasive solids wash across exposed sealing members. | Self-lapping metal discs and hardened alloy seats help maintain tight shutoff over repeated cycles. |
| Plugging or binding | Fine material accumulates in pockets around moving components. | Open-body configuration gives media room to move and be displaced as the valve opens. |
| High-cycle applications drive constant maintenance | Traditional valves degrade as cycling increases. | BMV disc rotation is beneficial in high cycling and self-laps and polishes surface over time. |
| Packing leaks and difficult service access | Actuation and valve internals are often too tightly packaged for quick field service. | Separated pneumatic actuator and valve arrangement supports field packing and inspection without removing the valve from the line. |
Sealing members would erode and have to be replaced on a weekly basis. Flapper style valves cycling once a minute wouldn’t always close against large chunks of 600°f vitrified coal ash trapped between its sealing members.
The Everlasting BMV (bulk material valve) was installed providing trouble free service in this high temperature (see options), high cycling application.
Production is moving granular abrasives with a bulk density of over 100 lbs/ft3.
Everlasting Valves replaced transporter feed knife gate valves that developed internal and external leakage. Transporter outlets, now fitted with Everlasting Valves, replaced ball valves that suffered packing leaks.
Our diverter valves have eliminated endless hours of maintenance in the finished product area that were previously spent repairing pinch valves. In each location the users enjoyed a fast pay back on their investment.
Applications
Use this section as an end-user navigation block: start with the application, then show the failure mode, EV design advantage, and next action.
Use BMV where hot ash, large chunks, or abrasive fines attack sealing members and prevent conventional flapper or gate valves from closing reliably.
Relevant for CKD, kiln fuel feed, clinker cooler areas, mill feeds, silo discharge, and other abrasive powder or granular solids locations.
Use for transporter fill, discharge, vent, filling, and transfer-line isolation where solids handling and shutoff reliability are both important.
Use BMV below collection points where fines, dust, and abrasive solids need dependable isolation without building up inside the valve.
Use where production is moving high-density granular abrasives and traditional knife gates, ball valves, or pinch valves are creating maintenance burden.
Specification Snapshot
Use this as a quick on-page spec card before sending users to the catalog or RFQ form.
For abrasive solids, high cycling, high temperature, large chunks, or recurring valve repair, send EV the application details and let the team confirm the right BMV size, body construction, trim, actuator, and accessory package.
