Usage Notes

• Always depressurize the pump or system before removing the ball to avoid injury or damage.
• Inspect the ball seat bore and surrounding components for wear, scoring or contamination prior to installation.
• Clean all mating surfaces thoroughly and ensure correct alignment during installation for optimal sealing.
• After installation, run a test cycle under normal operating conditions to verify seal integrity and flow performance.
• Replace the ball if you observe any signs of cracking, extrusion, surface degradation, or leakage past the seat.
