KNIFE GATE VALVE
The EX model knife gate valve is a wafer type valve designed for general industrial service applications. The
design of the body and seat assures non-clogging shut off on suspended solids in a wide range of industries such
as Pulp & Paper, Wastewater Treatment Plants, Food & Beverage, Mining, Power Plants, Chemical Plants, Bulk
Handling, etc.
Product description:
• Uni-directional wafer type knife gate valve
• Size range of DN50-1200 (larger sizes upon request). See Dimension Charts for pressure
rating
• Rising & non-rising stem configurations available
• Standard flange connection: DIN PN10 (EN 1092-2) and ANSI B16.5 (class 150)
Others available upon request
• Manual (handwheel, chainwheel, lever and bevel gear), pneumatic (single and
double-acting), electric and hydraulic actuation options available
• For EU Directives and other Certificates, please see the document:
Directives and Certificates Compliance - Knife Gate Valves - Catalogues and Datasheets
