I. Overview

The XAN-D pneumatic thin film low-temperature dual seat regulating valve is one of the modified products of the XAN pneumatic thin film dual seat regulating valve. It consists of a pneumatic thin film multi spring actuator and a low-temperature resistant dual seat valve. Key Features:

1. Upper and lower dual directional dual seat valves. The flow coefficient is larger than that of a single seat valve.

2. The unbalanced force of the two valve cores is basically offset, so the pressure resistance ability is stronger than that of a single seat valve.

3. Use a long necked upper valve cover to keep the packing box away from low temperature sources, ensuring sealing and safety of personnel operation.

4. The valve seat is fixed with grooves, with a simple structure, easy maintenance, and small valve seat leakage.

The pneumatic thin film multi spring actuator used has a large output force and a compact product structure; It is suitable for controlling low-temperature media such as liquid oxygen, liquid nitrogen, and liquid Freon, and for situations where leakage requirements are not strict.
