Manual Handwheel Round Port Lug Non Rising Stem Uni-Directional Knife Gate Valve

Compact, Reliable Isolation for Confined Spaces

This knife gate valve is specifically engineered for installations where vertical clearance is a major constraint but reliable, consistent isolation is required. The Non-Rising Stem design is its defining feature, maintaining a constant, low-profile height whether the valve is open or closed, making it ideal for pits, trenches, or crowded equipment areas.

Built for dependable operation, the valve features Uni-Directional sealing for secure shut-off against forward flow and a Lug-style body that simplifies pipeline maintenance and minimizes system downtime. This model is the perfect choice for compact, manual isolation in general industrial applications.

Key Features & Operational Advantages

Feature Category	Technical Detail	Operational Benefit
Space Optimization	Non-Rising Stem Design	Keeps the overall valve height constant, eliminating the need for overhead clearance and enabling installation in extremely confined spaces.
Maintenance Ease	Lugged Connection Body	Features individually threaded bolt holes, allowing for the isolated removal of the valve from the pipeline by disassembling the flanges from one side only.
Sealing Security	Uni-Directional Sealing	Guarantees effective, tight isolation against the full-rated pressure when the flow is from the designated inlet side.
Operation	Manual Handwheel	Provides simple, direct, and reliable actuation for manual control without requiring external power sources.
Flow Efficiency	Round Port Geometry	Ensures a full, unobstructed flow path when open, minimizing pressure loss and turbulence.
Reliability	Bonnetless Structure (Implied)	The simplified top-works design (common with this style) prevents particles and debris from accumulating, ensuring smooth cycling.

Target Industry Applications

This valve is indispensable in crowded or height-restricted industrial environments:

Underground/Subterranean Installations: Ideal for pits, trenches, or vaults in municipal and industrial sites where access is limited.
Low-Clearance Pumping Stations: Used in facilities with low ceilings, overhead ductwork, or tight equipment placement.
Process Skids & Machinery: Integration into packaged systems where footprint and vertical height are at a premium.
Wastewater & Utilities: Isolation in non-critical lines where flow is strictly one-way.

Note on Indication: Because the stem does not move, operators rely on the position indicator (usually a small pointer device attached to the actuator yoke) to visually confirm the valve’s status.
