Wafer Knife Gate Valve
This model knife gate is a uni-directional wafer valve designed for general industrial service applications. The design of the body and seat assures non-clogging shutoff on suspended solids in industries such as:
Pulp and paper Working pressure
Power plants
Wastewater treatment plants DN 50 to DN 250: 10 kg/cm²
Chemical plants DN 300 to DN 400: 6 kg/cm²
Food and Beverage DN 450: 5 kg/cm²
Bulk handling DN 500 to DN 600: 4 kg/cm²
Mining DN 700 to DN 1200: 2 kg/cm²
etc.
Standard Flange Connection Sizes
EN1092 PN10 and ANSI B16.5 (class 150) DN 50 to DN 1200 (larger diameters on request)
Note: other flange connections (on request):
EN1092 PN6/16/25

Hopper Shape Knife Gate Valve
This model knife gate is a wafer valve designed for industrial bulk handling service applications (powdered and granular products). The special design of the body allows for easy passage of the fluid and makes it ideal for use as silo outlet valve. This Knife Gate Valve is widely used in industries such as:
• Power plants
• Food and Beverage
• Chemical plants
• Mining
• etc.
The Knife Gate Valve is normally installed in the reverse position (seat upstream) in order to avoid problems like build-up in valve body, seat wear, difficult closing, etc.
