C73451-A430-D81: Pneumatic Block
The C73451-A430-D81 is a pneumatic block from Siemens designed for dual-action control of double-acting valves. Weighing 0.260 kg, it is a compact component that directs supply air to both sides of an actuator, enabling precise positioning in demanding industrial environments.
This block is specifically compatible with SIPART PS2 6DR5.2* electropneumatic positioners, where it serves as the interface between the positioner and the valve actuator. Its dual-action design supports applications requiring bidirectional movement, such as in process control loops for chemical, oil and gas, or power generation systems. The included seal and screws facilitate installation.
When selecting a pneumatic block, verify that the actuator is double-acting and that the positioner model matches the compatibility list. The C73451-A430-D81 is engineered to meet Siemens specifications for air flow and pressure, contributing to stable valve operation.
