Dorman Actuator Vacuum Check Valve

The Dorman actuator vacuum check valve (also called a vacuum check valve or one-way vacuum valve) helps maintain vacuum in the lines that operate vacuum-controlled actuators. It allows vacuum to flow in one direction and blocks it from flowing back. This keeps vacuum steady for the system it serves.

Key Features:

• One-way check valve design that holds vacuum and blocks reverse flow
• Helps keep vacuum-operated actuators working consistently
• Made to replace a worn, leaking, or failed check valve in a vacuum line
• Designed for a straightforward, direct-replacement installation
• Backed by Dorman's reputation for aftermarket replacement parts

A failing vacuum check valve can cause weak or inconsistent actuator operation, vacuum leaks, or lost vacuum hold. Replacing it helps restore reliable operation of the vacuum system. Choose the variant that matches your application from the options listed on this page.
