The 89543005 is a 3/2 normally open (NO) pneumatic valve assembly, supplied with an adaptor for mounting on Ø 22 mm manual actuators. It is designed to operate with a pressure range of 0 to 8 bar and features a 2 mm orifice, enabling a flow rate of 112 NI/min at 6 bars. The valve requires a control force of 12.6 N and offers a high mechanical life of 1.5 million operations. It functions reliably in dry air at temperatures from -5°C to +60°C, making it a durable choice for industrial pneumatic control panels.
