Features and Operation

  • The sliding-spool structure provides sealing performance in a compact valve.
  • The bore is specially processed to reduce friction and wear; installation and removal are straightforward.
  • Air lubrication is not required. If lubrication is used, continue it consistently with ISO VG32 or equivalent oil.

Flow and Performance Reference

Parameter Details
Printed technical-table reference 4H330C10
Reference effective area 21.3 mm²
Reference Cv 1.25
Plotted curve model 4H31010
Chart vertical axis Operating pressure, MPa; labeled range 0–0.7 MPa
Chart horizontal axis Air flow, L/min; labeled range 0–3200
Curve conditions Curves plotted across the shown operating-pressure range; individual curves have no separate printed labels

These numerical flow references apply to the explicitly printed models. The catalog does not separately rate every return, center or port variant. The plotted two-position curve is not a separate performance guarantee for a three-position configuration. AirTAC laboratory flow measurements are used to calculate the effective area and Cv; chart limits are not rated flow values.

Internal Components

The numbered items below reproduce the catalog internal-structure reference. Item numbers identify parts in the illustration; they are not quantities, replacement-kit order codes or a list of separately supplied accessories. The source uses 4H210 and 4HA230C reference sections; return and positioning components depend on the selected construction.

Series Ordering Options

4H denotes manual return and 4HA denotes spring return. Size 200 offers 1/8 and 1/4 supply/work ports; size 300 offers 1/4 and 3/8. Function 10 is 5/2; 30C is 5/3 closed center; 30E is 5/3 exhaust center. PT is the default thread; G and NPT are alternatives. The return construction and center function in the current SKU are the ordered configuration. The page does not publish a separate accessory-kit order code or kit quantity.

Reference Weight

Estimated reference weight: 245 g. The reference is 4H330, published at 245 g. This 4HA operating-mechanism variant is referenced to the corresponding 4H size and position count; the different mechanism is not separately mass-adjusted. The current option differences are not individually weighed; this weight analogy does not establish technical or mounting interchangeability. This is a reference estimate, not a manufacturer-published weight for this exact configuration or an individually measured or packaged shipping weight. Actual supplied mass can differ.
