A useful electric actuator RFQ gives the supplier enough information to check the actuator, control package and valve interface before quoting. A short message such as “need actuator price” usually leads to slow follow-up. The best request includes the model code, nameplate photo, valve data and operating conditions.
Minimum RFQ checklist
| Item | Why it matters |
|---|---|
| Brand and model code | Helps identify the actuator family, frame, control unit and possible options. |
| Nameplate photo | Reduces the risk of missing voltage, torque, duty, enclosure or certification details. |
| Valve type and size | Confirms whether the application is gate, globe, ball, butterfly, damper or another valve type. |
| Torque or thrust requirement | Supports sizing review and safety margin discussion. |
| Power and control signal | Checks compatibility with site wiring, PLC/DCS and local control expectations. |
| Environment and certificates | Helps review enclosure, temperature, corrosion, hazardous-area or document requirements. |
For replacement projects
When replacing an installed actuator, send photos of the actuator, control unit, terminal box, valve mounting and any old quotation or datasheet. If the actuator is mounted on a gearbox, include the gearbox nameplate and valve tag. This helps avoid a quote that fits the actuator model but misses the site interface.
For new valve automation projects
For a new actuator selection, provide the valve type, valve size, required movement, torque or thrust, operating frequency, fail position, power supply, control mode and site environment. If the valve manufacturer has a recommended actuator size, include that document with the RFQ.
Common brands and categories
JSSS Nova can support RFQ preparation for brands and categories such as Rotork, AUMA and Electric Actuators. For urgent checks, use the RFQ page and attach model or nameplate information where possible.
Practical RFQ format
- Subject: Brand + model + quantity + project country.
- Body: application, valve type, voltage, control signal and required documents.
- Attachments: nameplate photos, datasheet, old quotation, wiring diagram or valve data.
- Questions: request price, lead-time indication, document availability and possible alternatives if exact configuration is not available.
FAQ
Can I request a quote without a complete model code?
Yes, but a quote may need more review. Photos, valve data and site details can help fill the gap.
Is torque always enough for actuator selection?
No. Torque is important, but duty, operating time, power, controls, mounting and environment also matter.
Should I send the valve tag number?
Yes. The tag number helps connect the actuator request to plant records and project documents.
Can the supplier choose a cheaper alternative?
Possible alternatives should be reviewed carefully. Do not treat them as direct replacements until the technical details match the site requirement.
