GGG40 Knife Gate Valve, DN50, PN10, Bidirectional, Wafer Ends

Key Specifications / Features

The GGG40 Knife Gate Valve features a ductile iron body with bidirectional shutoff, ideal for handling challenging media. With a 2-inch (DN50) size, PN10, and Class 150 LB pressure rating, it offers reliable performance in various applications. The valve includes a wafer end connection and is manually operated, ensuring efficient flow control and durability in industrial systems.

The Bidirectional Knife Gate Valve is engineered for optimal shutoff performance, designed to efficiently handle various flow directions and challenging media. Featuring a maintenance-free compact cross seal with a double seal lip profile, the valve ensures tight shutoff and can be adjusted without interrupting ongoing operations. A self-cleaning effect is achieved through flush-out corners and the cutting edge under the gate, which cuts solids and fibers before tightening the valve against the elastic seat. The lateral guidance of the gate prevents fluttering in any flow direction or during throttle positions, guaranteeing long service life and reliable operation.
