Questions appear only when a published record or linked PDF page provides the answer.

How many hoses are currently listed for Hitachi EX270LC Control Valve?

There are 10 published records. 10 include a length, both end fittings, and a part number or diagram pipe number.

What is the hose length range for Hitachi EX270LC Control Valve?

Based on published records with valid lengths, the range is 500–1,480 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Hitachi EX270LC Control Valve?

The most frequent raw specifications in the current published records are: DN10;1层纤维-6;14MPa (5 records), DN6;2层纤维-4;14MPa (4 records), DN10;2SN-6;27.5MPa (1 records). Verify the specification together with length, pressure, and fitting details.

How can I identify the left and right hose fittings for Hitachi EX270LC Control Valve?

Each record keeps the left and right fitting descriptions separate. Current examples: 4203100: left 美制外螺纹37°外锥; right 90°美制内螺纹37°内锥; 4203104: left 美制内螺纹37°内锥; right 90°美制内螺纹37°内锥; 4203096: left 美制外螺纹37°外锥; right 90°美制内螺纹37°内锥. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.
