Product catalog summary

Component Identification and Spare Parts Listing

This document section appears to list various mechanical components, likely parts of a valve or actuator assembly, along with indications of which parts are considered spare or critical.

Main Components and Details:

Body (10.10): Marked with an asterisk, indicating importance or availability as a spare.
O-Rings: Multiple O-Rings are listed at different reference numbers (10.40, 15.30, 20.05, 20.40, 30.55, 30.110, 30.130, 30.140, 30.150), many marked with an asterisk, highlighting their critical role in sealing and maintenance.
Plug and Plug Gasket (10.50, 10.50.60): Both marked with an asterisk, suggesting they are key components or spares.
Bonnet (20.15): Marked with an asterisk, indicating significance.
Stem with bellow (20.30): Marked with an asterisk, likely a moving part requiring attention.
Lip Seal (20.50): Listed without an asterisk, possibly less critical or not a spare.
Guide Bushing (20.60): Not marked, possibly standard or non-spare.
Piston Tube (30.30): Marked with an asterisk, important for operation.
Compression Spring (30.70): Marked with an asterisk, essential for mechanical function.
T-DUO Sleeve (30.120): Marked with an asterisk, indicating a spare or critical part.
DU-Bushings (30.160, 30.170): One marked with an asterisk, the other not, suggesting different criticality.
Protection Cover (40.10) and Limit Switch (40.20): Both marked with an asterisk, important for protection and control.
3/2-way Solenoid Valve (50.10): Marked with an asterisk, indicating a key control component.

Summary of Critical Points:

Asterisks denote parts that are either critical for operation or recommended as spares.
O-Rings are numerous and critical, emphasizing the importance of sealing components.
Mechanical moving parts such as the stem with bellow, piston tube, and compression spring are highlighted.
Control and protection components like the limit switch and solenoid valve are also emphasized.

Recommendations:

Maintain an inventory of all asterisk-marked parts as spares to ensure operational reliability.
Regular inspection and replacement of O-Rings to prevent leaks.
Ensure proper maintenance of mechanical and control components to avoid failures.
