Rising Stem Knife Gate Valve
The Rising Stem Knife Gate Valve is engineered for precise flow control and reliable shutoff in slurries, viscous fluids, and abrasive media. Unlike standard knife gate valves, the rising stem design allows for visual indication of valve position, easier operation, and reduced wear on the gate and seats. This makes it ideal for industries such as mining, pulp & paper, wastewater treatment, and chemical processing.

Rising Stem Knife Gate Valve – FAQ
A rising stem knife gate valve features a stem that moves up and down as the valve opens or closes, providing a visual indication of the gate position. It is designed for reliable flow control in slurry, viscous, and abrasive media applications.
Unlike standard valves, the rising stem design allows operators to see the valve position, reducing the risk of accidental operation and making maintenance easier. It also reduces wear on the gate and seat during operation.
Typical sizes range from 2" to 48", with pressure classes from PN10, PN16, up to ANSI 150–300. Custom sizes and pressure ratings are available upon request.
Common body materials include cast iron, carbon steel, stainless steel, and duplex alloys. Seat options include resilient rubber, PTFE, or metal, depending on application requirements.
Valves can be operated manually, with gear, or through pneumatic, hydraulic, or electric actuators for flexible integration.
Yes. The reinforced gate, durable body, and rising stem design make these valves ideal for abrasive, viscous, and solid-laden media in industries such as mining, pulp & paper, and wastewater treatment.
