Product Overview
The HAM-LET M20-4VKLC(M5)-M4-R&R-15 is a precision-engineered needle valve designed for fine flow control in hydraulic, pneumatic, and general process systems. Manufactured by HAM-LET, a globally recognized leader in high-pressure instrumentation and fluid control components, this valve utilizes a threaded stem and tapered needle tip to deliver accurate, repeatable throttling and shut-off capability. The M20 series is constructed for demanding industrial environments where precise metering, bubble-tight sealing, and long service life are critical. Its compact body design and multiple port configurations make it an ideal choice for panel-mounted instrumentation, sampling systems, and low-to-medium pressure hydraulic circuits requiring exact flow regulation.

Engineering Features & Advantages
- Precision Flow Metering: The tapered needle and fine-thread stem allow extremely accurate, repeatable adjustment of flow rate, making it ideal for sensitive hydraulic and pneumatic control loops.
- R&R (Replaceable & Repairable) Design: The valve seat and stem assembly can be serviced or replaced without replacing the entire valve body, significantly reducing downtime and maintenance costs.
- Leak-Tight Shut-Off: Metal-to-metal seating ensures bubble-tight closure when fully engaged, preventing unwanted fluid migration in critical process lines.
- Compact & Robust Construction: The M20 series body is machined from high-grade materials to withstand vibration, thermal cycling, and corrosive media in industrial environments.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original HAM-LET M20 series specifications, ensuring drop-in replacement without system modification.
Typical Industrial Applications
This needle valve is widely deployed in hydraulic and pneumatic instrumentation circuits, including: oil and gas sampling systems for precise flow control of corrosive or high-purity fluids; chemical processing plants where accurate dosing and shut-off of aggressive media is required; power generation
