In a plant where slurry, pulp, or viscous liquids push the limits of ordinary valves, the 150mm knife gate valve stands out as a dependable workhorse. It combines rugged construction with precise control, delivering a clean cut through challenging media while ensuring a tight seal when the line needs to stop. Operators trust its straightforward operation, knowing downtime and leaks are minimized even after years of hard service.
Why the 150mm size matters is simple: DN150 sits at a practical sweet spot for many process lines. It handles substantial flow without the bulk of larger sizes, fits standard piping, and remains easy to install, inspect, and service. Whether upgrading an existing system or specifying new equipment, a 150mm knife gate valve offers versatility, compatibility, and a compact footprint that suits space-constrained installations.
Key features to know
- Knife gate design: a sharp, hardened blade shears through solids and viscous media, reducing clogging and easing shut-off even with challenging contents.
- Sealing options: resilient elastomers or PTFE-based seats provide bubble-tight shut-off across a range of temperatures and chemical exposures.
- Materials and construction: bodies in ductile iron or stainless steel, with a corrosion-resistant gate and stem; options for lined or reinforced configurations to extend life in abrasive or acidic environments.
- End connections: available in wafer, lug, or flanged styles to match existing piping and standards.
- Actuation: manual handwheel for simple control, with pneumatic or electric actuators for automated, fast-orchestrated operations.
- Maintenance-friendly: modular seats and blades allow straightforward replacement in the field, reducing maintenance cycles and total cost of ownership.
