Type 1500 - T1500 Indoor Use/General Purpose - Positioner Control Valve
The Bellofram Precision Controls Type 1500 is a compact 4-20 mA electro-pneumatic transducer designed for proportional pressure control of valves, positioners, actuators, and other high-flow control devices. It converts a 4-20 mA electrical input into a pneumatic output range up to 0-30 PSIG, with flow capacity up to 6.5 SCFM and 0.75% typical accuracy. Inline, pipe, panel, DIN-rail, and manifold mounting options make the T1500 well suited to space-constrained machinery and multi-device control systems in machining, robotics, material handling, and liquid or gas processing.
