Stainless Steel Round Port Flanged Pneumatic Actuation Knife Gate Valve

Automated, Corrosion-Resistant Isolation for Process Fluids

This high-performance knife gate valve is the definitive choice for automated flow control in corrosive, chemical, or sanitary environments. Constructed entirely from Stainless Steel (SS304/SS316), it offers superior resistance to chemical attack and rust, ensuring longevity and media purity.

Equipped with a fast-acting Pneumatic Cylinder Actuator, this valve provides rapid, reliable on/off cycling necessary for modern automation systems. The robust Flanged connection offers maximum structural integrity and a high-strength seal, making it ideal for processes requiring secure, long-term isolation.

Key Features & Automation Advantages

Feature Category	Technical Detail	Core Operational Benefit
Material Durability	Stainless Steel Construction	Excellent corrosion resistance, ideal for mild acids, caustics, and process fluids where media purity or high hygiene standards are required.
Automation	Pneumatic Cylinder Actuator	Provides rapid, reliable, high-speed cycling, essential for frequent, automated on/off duties and emergency shut-off sequences.
Structural Security	Flanged Connection	Offers the highest structural rigidity and connection strength, ensuring a secure, leak-proof tie-in that resists pipeline stress and vibration.
Flow Efficiency	Round Port Geometry	Ensures a full, unobstructed flow path when open, minimizing friction and maximizing throughput for both general fluids and light slurries.
System Integration	Rising Stem Design (Typical)	The moving stem provides clear visual indication and facilitates the straightforward mounting of limit switches for precise remote position feedback.
Design Reliability	Bonnetless Design (Standard)	Prevents solid particles or thickened media from accumulating above the gate, ensuring consistent, jam-free automated operation.
