Vacuum Check Valves for Reliable Vacuum Retention

Vacuum check valves allow air to flow in one direction and prevent reverse flow when the vacuum pump stops or the system pressure changes. They help maintain the required vacuum level, reduce unwanted vacuum loss and support stable operation of vacuum equipment.

Our range includes membrane check valves with threaded connections and compact SMC non-return valves with one-touch or combined one-touch and threaded connections. They are suitable for vacuum pumps, vacuum generators, vacuum presses and industrial vacuum lines.

How to Choose a Vacuum Check Valve

When selecting a vacuum check valve, consider the operating pressure range, connection type and size, valve material, installation direction and required flow capacity. The valve must be suitable for the intended vacuum range and compatible with the connected hose, fitting or pneumatic line.
