Stainless Steel Round Port Flanged Manual Handwheel Knife Gate Valve

Dependable Manual Isolation for Corrosive Service

This Knife Gate Valve is the industry standard for reliable on/off isolation in environments demanding superior resistance to corrosion, rust, and chemical attack. Constructed entirely from Stainless Steel (SS304/SS316), this valve is built for longevity, ensuring media purity and long service life.

The robust Flanged connection provides maximum structural integrity and a secure, high-strength seal to the pipeline, ideal for fixed installations. The Manual Handwheel operation offers straightforward, dependable control with minimal maintenance requirements. This valve is the ideal manual solution for critical, corrosion-prone pipelines.

Key Features & Structural Advantages

Feature Category	Technical Detail	Core Operational Benefit
Material	Stainless Steel Construction	Excellent resistance to corrosion and chemical attack, making it ideal for mild acids, caustics, and process fluids where media purity is essential.
Connection	Flanged Connection	Provides the highest structural strength and rigidity, ensuring a robust, secure, and leak-proof tie-in that resists pipeline stress and vibration.
Operation	Manual Handwheel	Ensures simple, reliable, and low-cost actuation without reliance on external power sources or complex control systems.
Flow	Round Port Geometry	Ensures a full, unobstructed flow path when open, minimizing friction loss and maximizing throughput for both general fluids and light slurries.
Safety & Indication	Rising Stem Design (Typical)	The stem moves vertically, providing an unambiguous, clear visual indication of the valve’s current open or closed status.
Design	Bonnetless Design (Standard)	The simple top structure prevents solids, powders, or fibrous media from accumulating above the gate, ensuring consistent, jam-free closure.

Target Industry Applications

This valve is indispensable in corrosive or high-hygiene environments that require robust, manual isolation capability:

Chemical Processing: Manual isolation of chemical streams, corrosive effluent, and high-purity fluid transfer.
Food & Beverage/Pharmaceutical: Used for isolating process lines where stainless steel construction is mandatory for cleaning and hygiene standards.
Water Treatment: Reliable isolation of chemical dosing lines and general corrosive utility water.
Pulp & Paper: Isolation of corrosive liquors, bleach lines, and chemical recovery process streams.

Upgrade Option: For operation on large-diameter pipelines, this valve is readily available with a Bevel Gear Operator to significantly reduce the manual effort required for cycling.
