The timer switches the input pressure applied to connection 1 to connection 2 after the set time delay has expired. The time delay can be continuously adjusted between 2 and 30 s using an adjusting knob . Order no. 540694 1 4 Pneumatic timer, normally open Pneumatic timer (delay valve). In the idle position, port 1 is connected through to port 2. The pneumatic timer is started by a pneumatic signal at the control port. After the set delay time has elapsed, it is reversed and reset to the initial position by a return spring after the signal has been removed. The time delay can be continuously adjusted between 2 and 30 s using an adjusting knob . Order no. 539759 5 Pneumatic preset counter The counter counts pneumatic signals backwards from a preset number. Once the zero position is reached, the counter gives a pneumatic output signal. – Type: Mechanical counter with pneumatic drive – Display: 5-digit, digit size 4.5 mm – Reset: Manual button or pneumatic signal – Pressure range: 200 – 800 kPa (2 – 8 bar) – Min. pulse length for actuator: 10 ms – Min. pulse length for reset: 180 ms – Counting frequency continuous operation: 2 Hz Order no. 152877 6 Pressure sequence valve The pressure of the control signal is infinitely adjustable with a pressure adjustment screw. – Design: Poppet valve with spring return – Operating pressure range: 180 – 800 kPa (1.8 – 8 bar) – Pilot pressure range: 100 – 800 kPa (1 – 8 bar) – Standard nominal flow rate 1 – 2: 100 l/min – Quick-action mounting system Quick-Fix Order no. 152884 4 5 6
