KF50 Pneumatic Bellows Sealed Angle Valve (Stainless Steel) with Fluorocarbon Bonnet Seal

Engineered from 304 stainless steel, this normally closed valve combines a robust stainless steel bellows design with Fluorocarbon seals to deliver isolation down to 10^-7 mbar for non-corrosive gas applications.

Key Features

• Standard KF50 (NW50) Flanges: Features Quick-Flange connections for rapid, tool-free installation and compatibility with standard high-vacuum lines.
• Bellows & Fluorocarbon Sealing: Stainless steel bellows isolation paired with high-grade fluorocarbon (Viton ®) seals ensures leak-tight integrity across standard operating ranges.
• Single-Acting Automation: Configured as Air to Open / Spring to Close for reliable fail-safe operation, complete with a 24V DC air control solenoid.
• 304 Stainless Steel Body: Smooth exterior body finish reduces outgassing and minimizes particulate accumulation.
• Wide Thermal Operating Range: Rated for line and ambient temperatures from -30°C to 150°C.
