Precision needle-type metering valve with PEEK or Teflon stem for precision needles BV-520PK 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.
The working part of the BV-520PK valve is made of Teflon or PEEK plastic. PEEK - polyetheretherketone (English (PEEK) Polyetheretherketone) is a polymer that is resistant to high-temperature effects, to the action of steam, radiation, has increased wear resistance. These properties, combined with high strength, resistance to dynamic influences, as well as X-ray transparency, made it possible to use it where previously the use of plastics was considered impossible.

BV-520PK - Ban Seok Precision Metering Valve 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.

BV-520PK Precision Metering Valve - Ban Seok is designed for use with precision needles. Its working (wetted) part is made of PEEK plastic (English PEEK - Polyetheretherketone) - a polymer that is resistant to high-temperature effects, to the action of steam, radiation, has increased wear resistance. These properties, combined with high strength, resistance to dynamic influences, as well as X-ray transparency, make it possible to use it where previously the use of plastics was considered impossible. BV-520PK - Ban Seok Precision Metering Valve is designed to handle UV curable and anaerobic adhesives. Since UV curable materials are supplied in opaque syringes or cartridges, the BV-520PK valve has been specially designed for quick and safe installation and replacement of such containers.
