Wafer Knife Gate Valve
Our Wafer Knife Gate Valves are high-performance isolation devices engineered for efficiency in systems handling demanding media such as slurries, viscous fluids, pulp, and dry bulk solids. The wafer-style body is designed to fit directly between pipe flanges, offering a space-saving, lightweight, and cost-effective alternative to traditional flanged gate valves.
Let’s Help You Specify the Right Knife Gate Valve
Be careful when choosing a new valve supplier, the disappointment of poor quality can last much longer than the joy of a low price!
Key Features & Benefits
Space-Saving Design: Features a slim, compact wafer body that minimizes required installation space and weight, reducing pipeline stress.
Reliable Isolation: Utilizes a sharp-edged gate (blade) for powerful shearing action to cut through media build-up and ensure reliable shut-off.
Versatile Sealing: Available with Resilient Seating (e.g., EPDM, PTFE) for bubble-tight sealing or Metal Seating for high-temperature and light abrasive applications.
Non-Clogging Operation: Minimal cavity space and optional recessed areas prevent media accumulation, ensuring the gate operates smoothly without jamming.
Simplified Maintenance: Designed for quick removal and installation, allowing for fast in-line maintenance and minimal downtime.
Actuation Options: Available with Manual Handwheel operation or various Pneumatic, Hydraulic, or Electric actuators for automated control.
