The 81527001 is a pneumatic air flow regulator designed for modular pneumatic timer systems. Based on the complementary products documentation, this component is part of Crouzet's pneumatic control system and features push-in connection capability for 0.4 mm semi-rigid tubing. The regulator is mounted on a sub-base and provides adjustable flow control through an orifice mechanism. It operates within a pressure range of 1 to 8 bar and is suitable for integration into pneumatic timing and control circuits. This component is commonly used in industrial automation applications where precise air flow regulation is required for pneumatic actuators and timing functions.
