2KLA pilot ordering reference
Helpful for Model Matching:
- Full 2KLA 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.
Catalogue Technical Specifications
| Actuation / state | Internally piloted, normally open 2/2. |
| Differential / proof pressure | Required differential 0.05–0.7 MPa; proof 1.5 MPa. Printed minimum 10 psi conflicts with 0.05 MPa: use MPa and confirm requirements. |
| Orifice / Cv / area | 150/200/250/320/400/500: 15/20/25/35/40/50 mm; Cv 5.5/9.5/12.5/23/31/49; area 100/170/220/420/560/880 mm². |
| Body / seal | SUS304 stainless steel; fixed PTFE (Teflon) seal. No seal-choice code. |
| Fluid / ambient temperature | Oil −10 to 150 °C; water 1 to 150 °C; steam maximum 183 °C, minimum not specified; ambient −20 to 100 °C. These are separate limits, not approval for every combined operating condition. |
| Viscosity caveat | Main row under 20 cSt; oil footnote 50 cSt or less. Confirm the applicable oil requirement. |
| Coil / protection | Valve pages specify Class H and IP65. AC50/60Hz ±15%, DC ±10%. Terminal blank, grommet I, wire length 0.5 m. |
| Coil selection / discrepancies | Use CDA110KH/CLA110KH for 030 and 150/200/250; CDA160KH/CLA160KH for 050 and 320/400/500. The K suffix denotes normally open, H denotes Class H. Page 196 gives a generic Class F table and different NO AC powers; confirm the actual coil label and power before replacement. |
| Temperature rise | Valve-page small coil: AC50Hz 50 °C, AC60Hz 45 °C, DC50 °C. Large coil: AC50Hz 65 °C, AC60Hz 60 °C, DC50 °C. |
| Published valve-page power | 150/200/250: AC50Hz 10 VA, AC60Hz 8 VA, DC6.5 W. 320/400/500: AC50Hz 25 VA, AC60Hz 22 VA, DC12 W. Generic NO coil table instead gives AC15/11 VA or 35/30 VA; confirm exact coil. |
| Mounting accessories | 150: F-2WA150LB; 200: F-2WA200LB; 250: F-2WA250LB. 320/400/500 have no mounting accessories per valve-page note. |

Quick check
Is 2KLA a normally closed replacement?
No. 2KLA is normally open; its unpowered state differs from normally closed 2LA. Confirm the required fail state and the direct or internally piloted structure.
Which pressure and temperature limits apply?
Direct standard/H maximum differential is 0.7/1.5 MPa, proof 3 MPa. Internal pilot requires 0.05–0.7 MPa, proof 1.5 MPa. Oil −10 to 150 °C, water 1 to 150 °C, steam max 183 °C and ambient −20 to 100 °C are separate limits; submit actual conditions together.
Can I select a replacement coil from the generic table alone?
Use the NO K and Class H selection for 2KLA. Valve-page and generic NO power values differ; confirm the original coil label, voltage, entry and power. Send standalone coil codes for consultation.
