The Festo VBNF Series Check Valve includes a piloted non-return function and manual exhaust function. The piloted non-return function can be used for a brief intermediate stop. If there is a control signal, the exhaust air can escape. If there is no control signal, the valve blocks the exhaust air of the drive and the drive stops briefly. 

A pneumatic drive can be manually exhausted by actuating the integrated manual exhaust function.
