The Knife Gate Valve is designed for reliable isolation in demanding slurry and bulk handling applications. Featuring a robust SG iron body and a semi-lugged wafer design, this valve ensures durability, corrosion resistance, and long service life in abrasive environments.

Equipped with dual replaceable elastomer sleeves, the valve provides bi-directional sealing, ensuring tight shut-off in both flow directions at maximum operating pressure. The full bore design allows unrestricted flow, minimizing pressure loss and improving system efficiency.

The smooth internal bore eliminates grooves and cavities where sediment or slurry can accumulate, reducing maintenance requirements. A protected spindle system, complete with a spindle cover and bellows, safeguards against contamination from splatter and harsh operating conditions.

Available in sizes from DN50 to DN600 with varying pressure ratings, this valve is ideal for industries requiring efficient flow control, abrasion resistance, and dependable shut-off performance.

Key Features:

• Bi-directional sealing with dual elastomer sleeves
• Full bore unrestricted flow design
• No cavities or grooves to prevent slurry build-up
• Semi-lugged wafer type body for versatile installation
• SG iron body (BS 420/12) for strength and durability
• Stainless steel gate (304 standard, 316 optional)
• Protected spindle with cover and bellows
• NR body seals for reliable sealing
• FBE coated mild steel yoke (stainless steel optional)
• Flange compatibility: DIN PN10 (other drillings available)
• Size range: DN50 – DN600
• Pressure ratings: up to 16 Bar (size dependent)

Applications:

Ideal for slurry, wastewater, mining, and bulk material handling systems where reliable isolation and minimal maintenance are critical.

The Knife Gate Valve delivers efficient, low-maintenance performance with robust construction and long-term reliability.
