Product Overview
The SPIRAX SARCO LE33PTSUSS-2 / 9126E / EP5 is a premium pneumatic control valve assembly engineered for precise throttling and on/off regulation of process fluids in demanding industrial environments. Manufactured by Spirax Sarco, a global leader in steam and fluid control technology, this valve combines a robust pneumatic diaphragm actuator with an integrated EP5 electropneumatic positioner. The LE33PTSUSS-2 valve body features a single-seat, globe-style design with stainless steel construction (indicated by the “SS” suffix), ensuring exceptional corrosion resistance and longevity. The 9126E actuator provides reliable spring-return fail-safe operation, while the EP5 positioner delivers high-resolution 4-20 mA signal feedback for accurate stem positioning. This assembly is specifically designed for modulating control loops where precise pressure, temperature, flow, or level management is critical, making it an ideal choice for steam, water, and non-aggressive process fluid applications across various heavy industries.
