Features and Operation
Sliding-spool structure provides sealing and responsive switching. Special bore processing reduces friction and starting pressure and supports long service life. Manual override assists installation and commissioning; added lubrication is not required. Matching manifolds allow compact valve groups. NC: de-energized P blocked and A connected to R; energized P connected to A and R blocked. P=supply, A=outlet, R=exhaust; refer to the pneumatic symbol.
External and Mounting Dimensions
All dimensions below are in mm for 3V210, lead-wire configuration. Linked PDF: third page, printed p.47. The 2022 catalog also identifies the optional external-pilot port. Use each dimension with its own view and origin; do not combine the callouts into an overall length × width × height.
View / feature
Applicable dimensions (mm)
Side-view main dimensions
Overall axial span 109; body width 35; upper horizontal span 34.5.
Side fixing / manual pin
2 × Ø4.2 holes; pitch 25; horizontal offset 8.2; lower offset 15.2; manual pin projection 3.
Opposite face
Width 22; fixing centres across width 17; 2 × Ø3.3 holes, vertical pitch 30; lower fixing offset 12.7.
Drawing A / B / C / D
A=27.7; B=0; C=22; D=16.7, for 3V210-06. Refer to the dimension-line origins; letters are drawing dimensions, not voltage codes.
Main port callouts
3 × PT1/8; these are valve ports, not manifold supply/exhaust port sizes.
Pilot connection
Internal pilot; the optional M5 × 0.8 external-pilot hole shown in the series drawing is not selected by this code.

Assembly and Accessory Kit Contents
This product code identifies one valve. A manifold and blanking plates are separate accessories; the double-solenoid valve is still one valve, not two valves.
Parameter
Specification
Matching manifold
3V200M, for the 3V200 series; 1F–16F selects 1–16 stations. Blank/G/T selects PT/G/NPT manifold threads.
Manifold kit contents
Manifold base, base gaskets and screws. Individual gasket/screw quantities are not specified.
Blanking-plate kit
P-3V200M-R2; blanking plate and screws. Screw quantity is not specified.
Accessory conditions
40 μm filtered air; −20 to 70°C. Manifold port sizes and dimensions are separate from valve-body ports and dimensions.
Assembly features
Integrates valves of the same series to save space and cost; common inlet/exhaust and organized wiring aid fault finding; station count can be expanded.
Optional Manifold Dimensions
Series reference only: 3V200M, 2022 catalog printed p.81. The diagram shows assembled valves; B/BA and connector projections are not bare-base dimensions. Lettered callouts refer to that drawing; dimensions are in mm.

Flow Characteristics
Series reference: the plotted test model is 3V210-08-NO. The 2022 chart has pressure 0–0.7 MPa in 0.1 MPa steps and flow 0–2000 L/min in 400 L/min steps. These axes are not rated flow limits. The linked English chart uses psi. Curves are AirTAC laboratory test data; use the graph and actual pressure conditions, not an axis maximum, for selection.
The catalog states 17.0 mm² (Cv=1.0) for 3V210-08 and 3V220-08; these values are calculated from flow-test data. This is a different port-size group and is not assigned to the current model.
