Stainless Steel Pneumatic Actuation Round Port Through-Conduit Knife Gate Valve

Automated, Zero-Wear Isolation for Critical Pipelines

This elite knife gate valve is engineered for automated, high-stakes environments where media protection and operational speed are paramount. It combines the swift control of a Pneumatic Actuator with the superior integrity of the Through-Conduit body design.

When fully open, this valve creates a smooth, continuous bore that completely shields the valve seats and internal components from the flow media. Constructed entirely from Stainless Steel, the valve offers excellent resistance to corrosion and ensures process purity. This model is the definitive choice for fast, automated isolation in corrosive and protected-flow applications.

Key Features & High-Integrity Automation

Feature Category	Technical Detail	Core Operational Benefit
Flow Protection	Through-Conduit (Full Bore) Design	Eliminates seat wear and minimizes pressure drop in the open position by creating a completely smooth, shielded flow path—ideal for corrosive or mildly abrasive media.
Automation & Speed	Pneumatic Cylinder Actuator	Provides rapid, reliable on/off cycling and high thrust, essential for automated batch sequencing, emergency shut-off, and remote control integration.
Material Durability	Stainless Steel Construction	Excellent resistance to corrosion and chemical attack, ensuring longevity and integrity in aggressive fluid environments.
Sealing Security	Protected Seat Design	The valve seats and stem packing are shielded from the media when fully open, drastically extending service life and reducing maintenance frequency.
System Integration	Rising Stem Design (Typical)	Facilitates the easy mounting of limit switches and positioners for accurate, real-time feedback to your Plant Control System (PCS).
Structure	Flanged/Lugged Connection	Provides the high structural integrity required for the often-higher pressure ratings and demanding environments where through-conduit designs are employed.
