Data Sheet



Unidirectional, Stainless Steel, Metal Seated, Knife Gate Valve - KGV99

Our Knife Gate Valves are designed to meet the most challenging flow control requirements, combining exceptional performance and durability with ease of maintenance. Engineered with precision and adherence to MSS SP-81 standards, these valves provide an unmatched solution for handling difficult media and high-pressure environments.


Key features of our Knife Gate Valves include:

Quality Assurance: Each valve is designed, manufactured, and tested in accordance with the MSS SP-81 standard, ensuring top-notch performance and reliability.

Heavy-Duty Construction: The one-piece cast stainless steel body provides excellent resistance to deflection from line loads and internal pressure, ensuring long-lasting durability.

Non-Clogging Design: The full port design prevents clogging, making the valve suitable for various applications involving thick media and solids.

Enhanced Rigidity: The heavy-duty cast stainless steel yoke enhances structural rigidity and mechanical strength, while the double clevis pin design ensures maintenance-free reliability.

Uni-Directional Flow: Our Knife Gate Valves are designed for uni-directional flow control, allowing for smooth and efficient operation.

Robust Support: The heavy-duty stem nut accommodates axial and side loading, providing enhanced support and stability.

Guided Gate: The integral gate guide prevents deflection, ensuring a tight seal and optimal performance.

Adjustable Gland Retainer: The separate gland retainer, independent of the yoke, is fully adjustable and ensures high functionality and reliability.

Precision-Machined Gate: The double-sided machined gate reduces friction and torque, minimizing maintenance downtime.

Bevel Design: The gate's bevel design enables efficient shut-off capabilities in thick media.

Corrosion-Resistant Stem: The stainless steel stem and retainer protect against corrosion, extending the valve's lifespan.

Clockwise Closing: Our Knife Gate Valves come with a standard clockwise closing mechanism for easy operation.


Our KGV98 offer a superior flow control solution, combining robust construction, precision engineering, and versatile features to meet the most demanding applications. Choose our Knife Gate Valves for a dependable, maintenance-free, and high-performance flow control solution that can withstand even the harshest operating conditions.
