Clean-Check® Pneumatic Check Valve 2018-05-23T10:05:17+00:00

Product Overview

Aladco® Clean-Check® valve is a normally closed check valve that can be overridden by air piloting or manually to allow two-way flow. The tightly sealed Clean-Check® valves are used on pneumatic devices to stop air release when the device is stopped, which prevents drifting of the device and any attached load. Clean-Check® valves are unique in that they can be used in environments that need to stay very clean, but they also can tolerate exposure to external dirt and liquids.

The Clean-Check® valve is fully sealed for use in clean/sanitary environments without its function being affected. The valve is able to tolerate: dust, dirt, oil, grease, detergent, cleaning solutions and cutting fluids.

Application Information

A typical use of a Clean-Check® valve involves combining it with a direction control valve to control air flow from ports of a pneumatic device. With an appropriate combination of direction control valves and other pneumatic components, a cylinder position control system using a Clean-Check® can handle both normal position control and standby or safety stop conditions. An example schematic for a double acting cylinder is shown. A combined valve system can have excellent fail-safe and assured control properties.
