A slide gate that moves is one thing. A slide gate that closes reliably is what really matters.

In material-handling environments, buildup can create challenges for traditional gate designs. Small engineering details can make a big difference in addressing those challenges.

Plattco Slide Gates use roller bearing supports and a displacement pocket designed to help the gate move and close reliably when material accumulation becomes a factor.

It’s one more example of how the details behind the equipment can affect how it performs in the field.

Sometimes the most cost-effective equipment decision isn't buying something new.

It might mean keeping your current equipment in operation and maintaining a spare. It could mean refurbishing an existing component. Or it might mean modernizing when newer technology can address an ongoing maintenance challenge.

That's why looking at the entire equipment lifecycle matters.

For example, some cement plants replace large rotary valves during their annual shutdown. Removing the worn valve and installing a spare requires cranes, rigging, labor, and repairs, with annual costs that can reach $100,000–$150,000.

Changing the equipment strategy can change those long-term costs.

Plattco's Double Flap Valve can eliminate the need for annual crane and rigging operations while reducing wear, helping plants reduce lifecycle maintenance costs and disruption.

Did you know your Plattco valve doesn't have to rely on compressed air?

For applications where pneumatic actuation isn't the preferred choice, Plattco EVA provides a full-electric alternative for our Double Flap Airlock® Valves.

That gives equipment manufacturers another option when designing their systems and another way to approach the specific needs of an application.

The earlier we understand what you're building and what you need the equipment to do, the better we can work with your team to identify a valve solution that fits.

Because sometimes solving an application starts with knowing you have more than one option.

When your name is on the equipment, you want to be confident in every part that goes into it.

That's why the work behind the finished product matters.

Plattco works alongside OEMs during the design process to understand the application and identify valve solutions that can be integrated into their equipment and perform in demanding environments.

It’s about more than supplying a component. It’s about working together to help build equipment customers can depend on.

Because at the end of the day, what you build should be something worth standing behind.

Come take a walk through the Plattco facility with us.

There’s a lot that happens before a finished Plattco valve is ready to leave our facility.

From the foundry and precision machining to assembly, this tour gives you a look at some of the people, equipment, and processes behind the products our customers rely on.

It takes a team and a lot of attention to detail to bring all of those individual components together.

We’re proud of the work that happens here every day and the people who make it possible.

Your customers might never see every component inside the equipment you build, but they'll experience the difference those components make.

When equipment performs reliably, requires less maintenance, and keeps operations moving, it builds confidence in the company whose name is on it.

That's why the details matter.

Plattco works alongside OEM engineers to understand their applications and provide valve solutions designed to perform reliably as part of the larger system.

We're proud to play a role behind the scenes, helping our OEM partners build equipment their customers can depend on.

Sometimes the right solution starts with understanding what's creating the maintenance problem in the first place.

At Wilkes-Barre Materials in Pennsylvania, abrasive sandstone dust was creating significant wear on the plant's Plattco S8-Series Double Flap Airlock® Valves.

The maintenance team was changing seats and flappers three or four times a year, making valve maintenance a frequent and time-consuming job.

Plattco engineers worked with the team to address those challenges using the Mechanical Shaft Seal (MSS) and EZ Seat replaceable wear edge.

The improvements helped Wilkes-Barre Materials reduce maintenance costs, overtime labor, and downtime. The EZ Seat also allows the team to replace a six-pound wear component instead of a component weighing more than 30 pounds.

As Superintendent Rich Halliday Jr. shared:
"Plattco and their engineers worked with us trying different products to solve our wear and maintenance issues. The Plattco team provided us with a minimal cost, minimal maintenance solution."

It's a great example of what can happen when our engineers and customers work together to solve a specific operational challenge.

Plattco is proud to serve customers across Canada, and Bennett is helping us build those relationships one conversation at a time.

As Plattco's Canadian representative, Bennett works with customers across Canada to understand what's happening in their facilities and what they need from their equipment.

Every application is different. That's why the conversation considers the complete operation, including safety, reliability, maintenance needs, and process requirements, before determining the right approach.

We're glad to have Bennett connecting Canadian customers with the experience and engineering expertise of the Plattco team.
