Valve for signal start delay

|
|||||
This device, if air is supplied at port 1, lets the air go out from port 2 when the adjustable dwell time (pre-set by screw R) has elapsed. The air flow can then be interrupted by removing the air supply from port 1. The difference from the normally open version (see below) is that the screw R adjusts the dwell time and not the duration of the air impulse. | ||||||
