Section 01

Project Background

A refrigerator production line required vacuum control for refrigerator inner liner manufacturing.

The original positioner used in the vacuum control system had been discontinued, while the existing valve body was still in good condition and did not need to be replaced.

To avoid unnecessary valve body replacement, the customer needed a practical replacement solution using a new valve positioner together with a pneumatic actuator as a complete assembly.

Section 02

Customer Challenge

The main challenge was that the original positioner was no longer available, but the valve body was still usable.

Replacing the complete valve would increase cost, extend downtime, and affect production continuity. The customer needed a replacement solution that could keep the existing single-seat control valve body in service while restoring reliable vacuum control on the production line.

Section 03

POWERFLOW Solution

POWERFLOW provided a complete replacement assembly including a smart valve positioner and pneumatic actuator.

The solution was matched to the existing single-seat control valve body, allowing the customer to replace the discontinued positioner and actuator assembly without changing the valve body.

This helped restore the vacuum control function required for refrigerator inner liner production while reducing unnecessary equipment modification.

Section 04

Project Results

The replacement solution restored the vacuum control function without replacing the existing valve body.

By supplying the smart valve positioner together with the pneumatic actuator as a complete assembly, POWERFLOW helped the customer reduce unnecessary valve replacement cost and maintain production continuity.

Since installation in August 2020, the solution has supported the vacuum control system for refrigerator inner liner production, with the line producing around 5,000 units per day.
