Product Overview
The HIGHLIGHT TECH CORP BKF25-M is a manually actuated vacuum valve engineered for precise isolation and control of vacuum circuits in industrial process and pneumatic systems. Manufactured by Highlight Tech Corp (HTC), a recognized supplier of high-purity vacuum components, the BKF25-M utilizes a hand-operated bellows or diaphragm-sealed actuation mechanism to provide leak-tight shutoff without introducing elastomer outgassing into the flow path. As a general process and pneumatic valve, it serves as a critical isolation point between vacuum pumps, process chambers, and downstream instrumentation, allowing operators to manually interrupt flow for maintenance, pump changeover, or system venting. Its 25 nominal bore designation aligns with standard ISO-KF / NW25 vacuum flange interfaces, making it a direct-fit component in modular vacuum manifold assemblies.

Engineering Features & Advantages
- Precision Manual Metering: Handwheel actuation allows operators to modulate flow and achieve repeatable throttling positions, ideal for controlled pump-down and venting sequences.
- Leak-Tight Vacuum Isolation: Bellows or diaphragm stem sealing eliminates dynamic O-ring wear paths, minimizing outgassing and maintaining vacuum integrity over extended service cycles.
- Industrial Reliability: Built for continuous operation in process environments, with corrosion-resistant stainless steel wetted surfaces suitable for demanding vacuum duty.
- Direct Fit Replacement: NW25 / ISO-KF flange geometry ensures exact dimensional and functional compatibility with standard vacuum manifold and pump inlet configurations.
- Contamination-Free Flow Path: Metal-sealed construction reduces particulate generation, supporting clean process requirements in semiconductor, coating, and analytical instrumentation.
