Extended Flanged Knife Gate Valve

Extended Flanged Knife Gate Valve, ANSI 150 Rating, 20 Bar Pressure Capacity

Manually controlled bi-directional knife gate valve designed for use in abrasive slurry applications, including industries such as pulp & paper, power generation, wastewater treatment, chemicals, food & beverage, bulk material handling, and mining, with a maximum temperature of 120°C and pressure rating of 20 bar.

The Wivo 779/68 series is a flanged, bi-directional knife gate valve, rated for 20 bar pressure, and designed with two rubber sleeves reinforced with metal. Ideal for applications involving abrasive slurries, it is commonly used in industries such as pulp & paper, mining, and wastewater treatment. The blade's edge is precision-machined into a wedge shape that allows it to cut smoothly through the fluid.

Features:

· Monoblock construction, with larger sizes featuring reinforced ribs for added strength, supporting operation up to 20 bar pressure.

· Stem made from stainless steel for enhanced durability.

· Internal design ensures the gate is fully guided throughout its movement.

· Grease fittings enable lubrication of the gate.

· Drainage through the lower section, where a cover or splash guard can be fitted.

· During operation, rapid flow at the bottom of the valve helps flush solids from the body cavity, ensuring full gate travel.

· Rectangular stainless steel knife blade, polished on both sides, with a precisely machined edge for smooth cutting through the fluid.

· Valve seal made of two long-lasting, highly durable EPDM sleeves in constant contact, ensuring unobstructed flow.

· Easy-to-replace sleeves in case of damage.

· No seat cavities that can accumulate material, and no fluid contact with metal parts.

· Bi-directional flow capability.
