Key Benefits

  • Easy maintenance and rebuilds
  • Reduced inventory requirements
  • Replaceable wear parts

Dependability has never been more convenient

Discover the difference that a truly dependable knife gate valve makes for your process

TG Knife Gate Valves

Our valves outlast the competition because they are designed for the brutal conditions that are common in mining. We offer you a true bi-directional knife gate slurry valve with a self-flushing design and full port flow. Replaceable rubber sleeves protect the vital valve components and are one powerful reason it can withstand abrasive slurries. We are a knife gate manufacturer that uses high quality, premium materials for mining and industrial applications.



For even better customised performance, we offer many upgrade design features.

Quality is just the beginning—experience reduced inventory requirements and easy maintenance

Interchangeable Parts

Our new TG series valves and existing TGW valves can be purchased and stocked in pre-assembled kits. These kits consist of all the required components needed to quickly assemble the valve. Kits will provide simplicity to the stocking process and make actuator conversions a breeze. We have also improved flexibility in stocking by making parts interchangeable between our TG and TGW knife gate slurry valve series. The actuator kit, dust boot kit, wiper blade kit and gate are interchangeable for sizes 2in (50mm) to 24in (600mm). This means reduced inventory and faster rebuilds.

Easy replaceable wear sleeves and retainer flanges

Our wear sleeves and retainer flanges are designed to be replaced. Conventional valves must be rebuilt or disposed of when slurry causes inevitable damage. We asked why the standard was to replace a valve when instead the parts that are most exposed to wear can be replaced. These wear parts are our solution, saving you unnecessary expense while at the same time lowering your carbon footprint.

Your ideal knife gate valve – designed to meet your application requirements

Your operations are too important to trust just any valve. Our valves are specifically designed to excel in your application.

Ultimate wiper blade design

Our new and improved wiper blade is made of a high-hardness EPDM rubber. It cleans material off the gate while at the same time minimising the unwanted slurry discharge during actuation. The wiper blade assembly is included in the base valve kit, but can also be purchased separately as a kit. Many knife gate valve manufacturers do not provide solutions, engineering, and quality like we do. We help our customers solve slurry transfer issues with our slurry valves and slurry pumps.

Not only for mining—also ideal for industrial processes

In addition to being a perfect solution for tough mining applications, our knife gate slurry valves are invaluable for industrial and flue gas desulphurization processes that require high performance and reliability. It is crucial for a power plant to have reliable valves to keep the process moving so they can meet the demands and emission requirements without downtime.
