Process scope
This Yoshitake group combines electrically actuated, pneumatically actuated, and self-contained temperature-control equipment. It is not one interchangeable valve class: choose first by the required control signal and fail action, then by medium, pressure, temperature, and available utilities.
Project-specific checks
- Define whether the duty is on-off, modulating, or temperature maintenance; do not infer control behavior from the actuator name.
- Confirm available electrical voltage or pilot-air pressure and the desired loss-of-power or loss-of-air position.
- Check process pressure, temperature, flow range, shutoff requirement, and body/seat material compatibility.
- Provide installation, bypass, manual-operation, and maintenance requirements to the sizing review.
Final verification
This guide groups local Yoshitake catalogue pages for preliminary engineering review. The model-specific Yoshitake documentation, sizing calculation, materials confirmation, and applicable site requirements control the final order and installation decision.
