Stainless Steel Rising Stem Lugged Manual Handwheel Metal Seated Knife Gate Valve

Durable Isolation for Corrosive & High-Temperature Service

This knife gate valve is engineered to provide reliable, secure isolation in aggressive industrial environments where standard materials or soft seals would fail. Utilizing Stainless Steel construction (typically SS304 or SS316) for superior corrosion resistance and a Metal Seated design for robust high-temperature and high-abrasion service, this valve is built for longevity.

The Lug-style body ensures optimal maintenance flexibility, allowing for one-sided servicing without disrupting the entire pipeline. The Manual Handwheel and Rising Stem combination provides direct, dependable operation and clear position indication.

Key Features & Extreme Service 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 harsh industrial fluids.
Sealing Robustness	Metal Seated Design	Withstands high temperatures and high pressures better than soft seals, offering superior durability in abrasive or high-cycle applications.
Maintenance Ease	Lugged Connection Body	Features individually threaded bolt holes, allowing maintenance personnel to remove the valve from the pipeline by disassembling the flanges from one side only.
Safety Indication	Rising Stem Design	The vertical movement of the stem offers immediate, clear visual confirmation of the valve’s open or closed status, enhancing safety and monitoring.
Operation	Manual Handwheel	Provides simple, direct, and reliable actuation for dependable, low-maintenance control.
Flow & Design	Round Port & Bonnetless	Ensures a full-bore, unobstructed flow path and prevents solids from accumulating in the top-works.

Target Industry Applications

This valve is indispensable in corrosive and high-heat environments where reliability is paramount:

Chemical Processing: Isolation of chemical intermediates, mild acids, and corrosive wastewater streams.
Food & Beverage/Pharmaceutical: High-purity applications (with required surface finish) where SS316 is standard for sterilization and cleanability.
Power Generation: Isolation of steam, condensate, and high-temperature process fluids.
Pulp & Paper: Handling corrosive liquors and high-temperature stock lines.

Actuation Upgrade: For increased ease of operation on larger sizes, this valve is compatible with Bevel Gear Operators. For automation, a robust Pneumatic or Electric Actuator can be seamlessly integrated.
