The GRACO 556328 is a steel ball designed for actuator assemblies. It is made from chrome steel and is intended for use within Pneumatic/Electric Lube Sentry Valves, where it plays a critical role in the actuation mechanism.

Key Features:

• Ball
• 3/16 in. (0.1875 in. / 5 mm diameter)
• Chrome steel
• Pneumatic/Electric Lube Sentry Valves
• Precision-engineered for reliable actuation
• Durable chrome steel construction for long service life
• Consistent performance in demanding lubrication systems

Applications:
Used in actuator assemblies for GRACO Pneumatic/Electric Lube Sentry Valves, which are commonly found in industrial lubrication systems for machinery and equipment.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the actuator assembly and the overall lubrication system.
• Ensure the actuator assembly is clean and free from debris before installation.
• Handle the steel ball with care to avoid damage or contamination.
• Refer to the specific Lube Sentry Valve manual for detailed installation instructions.
• Regularly inspect the actuator assembly for wear or damage.
• Replace the steel ball if signs of wear or deformation are observed.
• Keep the lubrication system clean to prevent contamination of moving parts.
