Ball valve ARCO 753905 — hand-operated, 1 mm bore

Hand-operated ARCO ball valve model 753905 features a 1 mm bore designed for precise on/off flow control in small-diameter piping. This compact shut-off valve provides a simple manual operation and reliable sealing, making it suitable for instrumentation, laboratory setups and other systems that require accurate isolation of fluid lines. The valve body and internal components are engineered to maintain consistent performance in low-flow and low-pressure applications.

Advantages

The ARCO hand-operated ball valve offers straightforward manual control with a compact form factor that fits tight installations. The 1 mm bore delivers accurate shut-off for low-flow circuits, while the ball mechanism ensures low leakage and quick operation. Its construction supports repeated cycling and provides dependable sealing for applications where containment and isolation are critical.

Suitable for

• Instrumentation and measurement lines
• Laboratory fluid handling and test rigs
• Small-diameter sample or drain lines
• Low-flow pneumatic or hydraulic pilot circuits
• Maintenance isolation in compact piping assemblies

Key specifications

• Bore diameter: 1 mm
• Operation: manual / hand-operated
• Function: on/off (shut-off) valve
• Design: compact ball valve suitable for small-diameter piping
• Typical application range: instrumentation and laboratory use

How to use

Install the valve inline in the piping so that flow direction matches any marking on the body if present; tighten connections to recommended torque for the chosen fittings. Operate the valve by turning the handle to the open or closed position; the design provides a clear tactile stop for shut-off. For best results, cycle the valve a few times after installation to confirm smooth operation and proper sealing. Verify compatibility of the valve materials with the process fluid before commissioning.

Usage recommendations

Use the ARCO 1 mm bore ball valve in low-flow, low-pressure systems where precise manual isolation is required. Avoid using the valve as a throttling device for continuous metering; it is intended for on/off service. For environments with aggressive fluids or extreme temperatures, confirm material compatibility and consider additional protective measures.
