Precision needle-type metering valve for use with standard needles BV-520M BanSeok

Needle valves are used for the application of small doses of liquids from low to medium viscosity with high accuracy and repeatability.

The valve is opened by pulsating air flow pressure from the valve controller. The spring assists the valve to quickly return to the closed position for immediate shutoff of the flow. The valve has a second air inlet port that closes the valve at a controlled rate, thereby providing improved metering accuracy. The dose volume can be adjusted by turning the knob at the top of the valve.

BV-520M Precision Metering Valve - Ban Seok is designed for use with coordinate robots. They have high accuracy and repeatability of dosing and small dimensions. This valve does not have an additional inlet for closing air flow. The BV-520M valve is designed for use with all standard needles.
