2LA pilot ordering reference
Helpful for Model Matching:
- Full 2LA valve and coil code or label
- Direct or internal pilot; available inlet/outlet pressure difference
- Steam, hot water or oil: exact temperature, viscosity and concentration
- Port, thread, voltage, entry, mounting clearance, quantity and destination
- Choose the exact direct or internally piloted body size.
- Match terminal/grommet geometry, body flow direction and optional bracket scope.
- Confirm pressure difference and media/ambient temperatures separately.

Quick check
Which pressure differential applies to this model?
Direct standard/H maximum differential is 1/2 MPa respectively, with 3 MPa proof. Internal pilot requires 0.05–0.7 MPa, with 1.5 MPa proof. Send inlet and outlet pressures with the complete code.
Are steam or oil limits universal approval?
No. Confirm actual fluid, concentration, media and ambient temperatures. The viscosity row says under 20 cSt, while oil footnote says 50 cSt or less. The applicable oil requirement needs confirmation.
