Stainless Steel Lugged Rising Stem Resilient Seated Bevel Gear Round Port Knife Gate Valve

Reliable, Tight Isolation for Corrosive Fluids

This knife gate valve is engineered to provide dependable, bubble-tight isolation in fluid systems where corrosion resistance and tight shut-off are essential. Constructed from Stainless Steel (SS304/SS316), the valve body offers superior defense against rust and chemical attack.

The Resilient Seated design ensures zero leakage by utilizing an elastomer seal (e.g., EPDM, NBR) that wipes the gate clean upon closure. The Lug-style body maximizes maintenance flexibility, allowing for one-sided servicing without disrupting the entire pipeline. The Bevel Gear and Rising Stem combination offers direct, reliable operation and clear position indication.

Key Features & Operational Advantages

Feature Category	Technical Detail	Core Operational Benefit
Material Durability	Stainless Steel Construction	Excellent resistance to corrosion and chemical attack, ideal for mild acids, caustics, and process fluids.
Sealing Security	Resilient Seated Design	Guarantees bubble-tight (zero-leakage) shut-off, providing superior sealing for general liquids, wastewater, and clean fluids compared to metal seats.
Maintenance Ease	Lugged Connection Body	Features individually threaded bolt holes, enabling isolated removal and servicing of the valve from the pipeline without disturbing the inactive side.
Safety Indication	Rising Stem Design	The vertical movement of the stem offers immediate, clear visual confirmation of the valve’s exact open or closed status.
Operation	Bevel Gear	Provides simple, direct, and reliable actuation for dependable, low-maintenance control.
Flow Efficiency	Round Port & Bonnetless	Ensures a full, unobstructed flow path when open, minimizing pressure loss and preventing solids accumulation in the top-works.

Target Industry Applications

This valve is the workhorse for manual isolation in corrosive environments where a guaranteed tight seal is required:

Wastewater Treatment: Isolation of clean water, treated effluent, and non-abrasive process lines.
Chemical Processing: Handling corrosive liquids, mild acids, and chemical transfer lines.
Food & Beverage/Pharmaceutical: Applications requiring hygienic stainless steel and reliable, zero-leakage isolation.
Utilities: General industrial water service and cooling water systems.

Upgrade Option: For operation on larger pipelines or in remote locations, this valve can be easily adapted for a Bevel Gear Operator or a Pneumatic/Electric Actuator.
