Oreacle knife gate valves being manufactured

Impeccable Construction

Each Oreacle knife gate valve is custom fabricated, machined and assembled in house, to our engineer's exact specifications and requirements.
Oreacle knife gate valves can be manufactured in dozens of various alloys

Valve Body & Trim Materials

As metallurgy is dependent on application specifications, Oreacle valves are available in dozens of standard and exotic materials (e.g. carbon steel, Stainless Steel, Super Duplex, Titanium, etc).

Diameter & Pressure Class

From low pressure gravity feed applications to systems with up to 740 PSI, SlurryFlo manufactures the following Oreacle valves for line sizes up to 48":
ANSI 150: 
ANSI 300: 
285 PSI (MSS SP-135)
740 PSI (MSS SP-135)
Oreacle knife gate valves have many heavy-duty lifting points

safe handling

Multiple heavy-duty lifting points are strategically located and integral to each Oreacle knife gate valve. This provides options for safe handling and simplifies the installation process.

Upgrade Your Valve Game


Oreacle knife gate valves are manufactured in house (in Canada), allowing our engineers to adapt the top plate for any actuator type, brand and model. We also provide 'bare stem' valves for clients who prefer to handle the automation on site.

Oreacle knife gate valves can suit any actuator type, brand and model
