BOLA Control Valves
Material: Temperature resistance: Chemical resistance: Pressure: Vacuum:
PTFE, PPS from -20°C to +250°C +++ universal 6 bar suitable
Product description:
Valve body made of PTFE with bore dia. 6 mm. Holding plate and adjusting screw made of PPS. Two connectors for tubing and tubes including compression rings (PTFE) and screw nut (PTFE with glass fibres). By turning the adjusting screw the passage is closed and thus the volume flow can be manually regulated (without regulation scale), the opening degree of the passage is indicated by a protruding pin in the center of the adjusting screw. An engraved arrow on the valve body marks the flow direction which has to be taken into account during installation. Universal chemical resistance, the flowing product is only exposed to PTFE.
Applications:
For distributing liquids or gases. Manual regulation of the flow rate by turning the adjusting screw.
