PRODUCT ADHESION

PRODUCT ADHESION

STRESS ON THE DRIVE

REDUCED THROUGHPUT

Excessive stress on the rotary valve drive can increase friction and resistance, creating conditions that encourage product buildup and adhesion inside the valve.

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.

As the product gets stuck inside a valve, it adds more stress to the drive, as well as limiting pocket fill.

PRODUCT SOLIDIFICATION & ROTOR SEIZING

When sticky product sits inside a rotary valve, it can solidify and build up around the rotor. Over time, this buildup can cause the rotor to seize, potentially leaving the valve unable to operate.

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

Radius Pockets

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

Long Running Valves

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

Knife Edges

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

Bearings Changable In-Line

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

ENB
Coating

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

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.
