Safety Related Notes
Before working on this machine, perform lockout-tagout procedures per the rules of your plant. Determine the sources of energy on this machine – electrical, pneumatic and hydraulic – and release or vent sources of stored energy – electrical capacitors, air receivers, and hydraulic accumulators. Shut off sources of power – electrical, pneumatic and hydraulic. Safely block mechanical sources of energy such as loaded springs and loaded machine members, or safely position the machine members so they are unloaded and springs are not under tension. Beware of hot hydraulic fluid and hot surfaces which can cause burns. Never “crack a hydraulic or pneumatic fitting” to check for the presence of stored energy. Hydraulic fluid injection injuries, as well as injection injuries from many other fluids, are extremely serious and must be treated immediately by medical personnel familiar with this type of injury. Loss of body parts or death may result from improperly treated fluid injection injuries! Never use your hands to feel for a hydraulic leak! Review the schematics and think before proceeding to work on the machine to ensure you have made the machine safe to work on.
Component:
167.24
Description:
Pilot Operated Check Valve Module
Manufacturer:
Rexroth
Part Number:
SV10PB1-40/
Stock Code:
Not Provided
Electrical Address:
Not Provided
Component Application:
When Directional Control Valve 306.05 is actuated to the crossover flow pattern, the pilot pressure port of this check valve is vented and the check valve closes, preventing fluid from the rod end of the CVC Entry Side Bottom cylinder on F5 from extending due to external load forces. When Directional Control Valve 306.05 is actuated to the parallel flow pattern, pilot pressure is applied to the pilot port of the check valve, opening the check valve, allowing Servo Valve 353.10 to control the extension and retraction of the cylinder.
