Norgren 04 series 0.2ms to 0.4ms Pneumatic Timer, 10 bar max

Impulse Generator. Fitted between a trip valve and directional control valve when it is necessary to eliminate a trapped or locked pilot signal that would otherwise prevent the control valve from resetting. When an input signal is applied, it generates a short duration output signal, which is then automatically exhausted. A further output signal cannot be generated until the input signal has been removed Will provide an output signal pressure of 90% of the input pressure. The downstream volume of the tubing and pilot chamber of the control valve should not exceed 0.033 dm ;sup>3 ;/sup>. This volume is equivalent to approximately 6.5 metres of 4mm o/d nylon tube Impulse duration 0.2 - 0.4s
