Industrial R300-SPDT-CO Valve Position Indicator

BLX's R300 SPDT-CO Valve Position Indicator is a compact local signaling device for industrial valves, delivering a single-pole double-throw (SPDT, changeover) contact and a front-cover indicator that visually confirms whether the valve is open or closed. Versions are available for DC control voltages of 30, 115, 125, 230, and 250 V, making it adaptable to many control systems. This device provides direct valve-position signaling suitable for integration with automation, safety interlocks, or process-control schemes, with a visible indicator on the valve bonnet for quick status checks. Some distributors list the R300 SPDT-CO as discontinued, which may affect current availability and sourcing.
