The 81503025 is a pneumatic YES logic element designed to provide on/off output signals based on input pressure thresholds in pneumatic control systems. This component features a 2.7 mm orifice diameter with a flow rate of 170 NI/min at 6 bars, operating across a pressure range of 2 to 8 bars. The device operates reliably over a temperature range of -5°C to +50°C and delivers exceptional mechanical durability with over 10 million operations. The YES element is commonly used in industrial automation, pneumatic logic circuits, and control systems where conditional signal routing and logic operations are required, offering 100% pneumatic operation without electrical components.
