Slurry Knife Gate Valves

What is a slurry knife gate valve?

A slurry knife gate valve is a specialized flow control device engineered to provide zero leakage isolation of abrasive, viscous or corrosive slurries. Unlike standard valves, slurry knife gate valves feature robust construction and achieve sealing of the gate against polymer sleeve seats to deliver repeatable shutoff in an action that prevents jamming. Designed for durability and performance, these valves are ideal for applications in mining, pulp & paper and power generation where conventional valves often fail. Emerson’s Clarkson Slurry Knife Gate Valves exemplify precision engineering and rugged reliability, empowering operators to improve safety and throughput in in the harshest conditions.

What is a slurry knife gate valve sleeve?

Sleeves are the heart of your knife gate valve. These unassuming black polymer rings are the critical components that contain your process line pressure and the often-hazardous media that flows within. Emerson’s Clarkson Slurry Knife Gate Valves are engineered to excel in these conditions. And when it comes time to replace the sleeves, only genuine Clarkson sleeves will ensure the same integrity of your processes. Don’t entrust the safety of your people, plant, and the environment to anything less than the genuine article.

Clarkson Slurry Knife Gate Valves are a Capital Investment

Lower total cost

Invest in superior technology for challenging slurry applications to extend service intervals and minimize repair costs.

Longer run-time

Sleeves are supported by a fully encapsulated stiffener ring that resists the heavy shearing forces during actuation.

Extended life

Patented compound formulations maximize resistance to compression-set, tear, wear, rolling, bursting, and chemical attack.

Rapid repair

A simplified two-piece mirrored design requires no special tools or machining for rapid sleeve replacement.

Tight sealing

Optimized sleeve durometer ensures ideal compression on the gate to provide positive isolation and efficient actuation.

Improved safety

Clarkson sleeves contain your process media with integrity to keep your people, plant and the environment safe.

Proven quality

Each sleeve is rigorously tested by Emerson’s elastomer experts to ensure identical, industry-leading performance.

Local support

Emerson’s service center network stocks convenient spare parts kits locally for delivery when and where you need them.
