Product Overview
The HORIBA STEC MV-2273-PVF is a precision metering valve engineered for accurate, repeatable flow control in high-purity process gas and pneumatic delivery systems. Manufactured by HORIBA STEC, a recognized leader in mass flow control and precision fluid handling instrumentation, this valve utilizes a fine-threaded manual actuation mechanism that translates handle rotation into extremely fine stem displacement, enabling micrometer-level flow adjustment. Unlike on/off directional valves, the MV-2273-PVF is designed for continuous variable metering, providing stable, low-turndown flow regulation without pressure spikes or hysteresis. It serves as a critical control element in semiconductor fabrication, analytical instrumentation, and industrial gas panels where precise, drift-free flow setting is essential to process repeatability.

Engineering Features & Advantages
- Precision Performance: Multi-turn micrometer-style stem adjustment delivers exceptionally fine flow resolution, allowing operators to set and repeat low-flow rates with minimal dead band and stable regulation.
- Leak-Tight Shutoff: Precision-lapped seat and stem geometry provide reliable closure and consistent sealing, protecting downstream instrumentation from unwanted bleed-through.
- Industrial Reliability: Built for continuous operation in demanding process environments, with materials selected for corrosion resistance and long service life under repeated adjustment cycles.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original HORIBA STEC OEM standards, ensuring drop-in replacement without modification to existing gas panels or manifolds.
Typical Industrial Applications
This precision metering valve is widely deployed in semiconductor wafer fabrication gas delivery panels, analytical and laboratory instrumentation, high-purity specialty gas systems, and industrial process control skids where accurate, repeatable low-flow regulation is required. It is also suited to pneumatic calibration benches, R&D flow test rigs, and any process requiring fine
