Pneumatic Through-Conduit Knife Gate Valve
The Pneumatic Through-Conduit Knife Gate Valve is a high-performance valve solution designed for automatic and remote-controlled operation in demanding industries. Its through-conduit design ensures that when the gate is fully open, the flow path is completely unobstructed, minimizing pressure drop, preventing media accumulation, and protecting the sealing surfaces.
Equipped with a pneumatic actuator, this valve offers fast, reliable, and low-maintenance actuation, making it an ideal choice for large-diameter pipelines, abrasive slurries, and process automation systems.
Key Features
Through-Conduit Structure – Ensures full-bore flow, reduces turbulence, and extends seat life.
Pneumatic Actuation – Enables quick, efficient, and remote-controlled valve operation.
Fail-Safe Options – Configurable as fail-open, fail-close, or double-acting actuator systems.
Durable Design – Built to withstand abrasive, corrosive, and high-solid-content media.
Sealing Flexibility – Available in uni-directional and bi-directional sealing designs.
Automation Ready – Compatible with solenoid valves, limit switches, and positioners for process control.
