PRODUCT ADHESION

STRESS ON THE DRIVE

REDUCED THROUGHPUT

Product buildup inside the valve can increase the torque required from the drive, placing additional stress on the drive components. Over time, this added load can lead to premature drive wear and reduced equipment life.

Product adhesion can reduce rotary valve throughput by causing material buildup on the rotor and housing. This limits product flow, making the valve less efficient and reducing overall production.

PRODUCT SOLIDIFICATION

When the valve is shut down, product may harden inside the valve and adhere to internal surfaces, making it impossible for the valve to restart.

VALVE SEIZING

Product can build up on the housing ID and endcaps. As this buildup accumulates, it creates drag against the rotor, acting like a brake and increasing resistance. Over time, excessive buildup can cause the valve to slow down or seize completely.

Our Product Adhesion Package  offers the specialized features and protection you need to minimize product buildup, improve material flow, and maximize valve performance. . .

ENB
Coating

ENB coating is
utilized for its
outstanding release
capabilities,
eliminating product
adhesion.

Long Running Valves

Built with durable materials and precision to deliver long-lasting performance.

Radius Pockets

Prevent
material buildup and
promote a cleaner
release, especially
when used in
combination with an
ENB™ coating.

Bearings Changable In-Line

In less than 15 min per side, you change change our proprietary MAP Seal and Bearings systems in-line.

Knife Edges

The 1/16" landing
allows the vanes to
remove material
more cleanly,
cutting rather than
pulling it away.

Rebuild Any Make & Model

Extend the life of your equipment with our rebuild solution that restores performance.

With this package we can offer the following:

Ability To Move To A Direct Drive

Easily upgrade to direct drive for improved efficiency and reduced maintenance.

Valves That Are No Longer Availble

We can rebuild or replace hard-to-find or discontinued valves.

Inboard-to-Outboard Conversion for NFPA Compliance.

Flexibility to reconfigure your valve for NFPA compliance and safety requirements.
