Frequently Asked Questions

What is the primary function of a valve ball?

A valve ball provides positive sealing in check valve applications, preventing backflow while allowing forward fluid movement, maintaining system pressure, and ensuring proper directional flow control in sprayer systems.

Where are valve balls typically used in Graco equipment?

Valve balls are used in check valve assemblies within pump and manifold systems where positive sealing and backflow prevention are required for maintaining pressure and proper fluid direction.

Should the ball seat be replaced with the valve ball?

Yes, replacing both the valve ball and its corresponding seat simultaneously ensures optimal sealing contact and prevents premature wear of either component, extending service life.

How can I identify valve ball wear?

Valve ball wear may appear as visible scoring, flat spots, or surface imperfections that prevent proper seating, often manifesting as check valve leakage or pressure loss.

Where does it ship from?

If in stock, orders ship from Bedford Hill, New York for prompt delivery to your service location.
