How many hoses are currently listed for Hitachi ZX450LC-3 Control Valve?

There are 23 published records. 23 include a length, both end fittings, and a part number or diagram pipe number.

What is the hose length range for Hitachi ZX450LC-3 Control Valve?

Based on published records with valid lengths, the range is 300–1,850 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Hitachi ZX450LC-3 Control Valve?

The most frequent raw specifications in the current published records are: DN6;1SN-04;22.5MPa (11 records), DN10;1SN-06;18MPa (3 records), DN19;4SH-12;42MPa (2 records), DN25;2SN-16;16.5MPa (2 records), DN10;1SN-6;7Mpa (1 records). Verify the specification together with length, pressure, and fitting details.

How can I identify the left and right hose fittings for Hitachi ZX450LC-3 Control Valve?

Each record keeps the left and right fitting descriptions separate. Current examples: 4634390: left 美制内螺纹74°内锥; right 90°美制内螺纹74°内锥; 4642214: left 美制内螺纹74°内锥; right 45°美制内螺纹74°内锥; 4634388: left 美制内螺纹74°内锥; right 90°美制内螺纹74°内锥. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.

Can I locate a Hitachi ZX450LC-3 Control Valve hose by diagram pipe number?
