Knife Gate Valves

Pinch Valves and Hose Valves

Pinch valves, also known as hose valves, are highly suitable for handling abrasive media, slurry and other challenging process fluids. The process medium only comes into contact with the flexible rubber sleeve, keeping it completely isolated from the valve body and other internal components.

When fully open, a pinch valve provides a free and unrestricted flow path, reducing the risk of clogging, material build-up and excessive wear. The valve is operated by mechanically or pneumatically compressing the rubber sleeve, allowing it to be used for both shut-off and flow control applications.

Many industrial pinch valves are designed with a replaceable rubber sleeve, allowing the main wear component to be changed without replacing the complete valve. This provides a durable and cost-effective valve solution for demanding applications in industries such as mining, mineral processing, water treatment, chemicals and other slurry-handling processes.

Lined Knife Gate Valve

Our Lined Knife Gate Valves are designed for reliable on/off isolation in abrasive and corrosive process applications. The valve body and chest are fully lined with moulded rubber, protecting the metal components from direct contact with the process media.

The flush-bottom, full round port design eliminates cavities where solids can collect and provides zero discharge to atmosphere, making the valve well suited for slurry and other demanding media.

Wafer Knife Gate Valve

Our Wafer Knife Gate Valves provide a compact solution for slurry and abrasive media applications where installation space is limited. The full port design allows the gate to be fully isolated by the sleeves in the open position.

When closed, the gate moves between the sleeves to provide a bi-directional bubble-tight seal with zero downstream leakage. Solids are purged through the bottom of the valve housing, helping prevent clogging and gate jamming.

Flanged Knife Gate Valve

Our Flanged Knife Gate Valves are designed for reliable bi-directional isolation in abrasive slurry applications, including mining and mineral processing.

Heavy-duty rubber sleeves protect the valve from wear, while the gate passes through the sleeves during closing. Solids are purged through the bottom of the valve housing, helping prevent clogging and gate jamming.

High Pressure Slurry Knife Gate Valve

Our High Pressure Slurry Knife Gate Valves are designed for reliable bi-directional isolation in demanding high-pressure slurry applications, including mining and mineral processing.

Heavy-duty rubber sleeves provide sealing and wear resistance, while the gate passes through the sleeves during closing. Solids are purged through the bottom of the valve housing, helping prevent clogging and gate jamming.

Severe Service Lined Knife Gate Valve

Our Severe Service Lined Knife Gate Valves are designed for abrasive, corrosive and other demanding process applications. A two-piece valve body secures wear-resistant rubber around the gate edge, forming a protected U-shaped bi-directional seal inside the valve body.

The double-layer sealing system uses an inner seal to isolate the process flow and an outer seal to prevent leakage to atmosphere, providing extended service life and reliable containment in severe-duty applications.

Urethane Lined Knife Gate Valve

Our Urethane Lined Knife Gate Valves are designed for abrasive and corrosive on/off applications. A one-piece, field-replaceable urethane liner provides high flow with low pressure drop while protecting the valve from wear.

The flush-bottom, full round port design eliminates pockets where solids can collect and provides zero discharge to atmosphere.

Severe Service Wafer Sleeve Knife Gate Valve

Our Severe Service Wafer Sleeve Knife Gate Valves are designed for demanding on/off applications involving abrasive slurry and other challenging media. A robust metal-covered rubber or urethane sleeve provides bubble-tight shut-off, while urethane or high-chrome wear rings improve wear resistance.

The flush-bottom, full round port design eliminates pockets where solids can collect and provides zero discharge to atmosphere, improving reliability and service life.

Lined Moulded Knife Gate Valve

Our Lined Moulded Knife Gate Valves are designed for reliable on/off isolation in abrasive and corrosive process applications. The valve body and chest are fully moulded with rubber or urethane lining to protect the valve from wear and chemical attack.

The flush-bottom, full round port design eliminates pockets where solids can collect and provides zero discharge to atmosphere.
