Product Overview
The Flowserve 3821-28EA-D43R-0110-00 Logix 3800 Digital Valve Positioner is designed for precise positioning and automated control of pneumatic valve actuators in industrial process systems. Manufactured by Flowserve, this intelligent electropneumatic positioner uses a standard 4–20 mA electrical control signal with HART digital communication to regulate pneumatic output pressure and maintain accurate valve positioning. Its double-acting configuration delivers controlled instrument air through two pneumatic outputs, supporting responsive actuator movement, stable flow regulation, and dependable performance in demanding industrial environments.
Part of the Flowserve Logix 3800 series, the 3821-28EA-D43R-0110-00 features microprocessor-based control, non-contact magnetic position sensing, automatic calibration, and digital diagnostic capabilities. This configuration includes an aluminium explosion-proof housing, three stainless steel pressure gauges with right-side orientation, an LCD display, and a stainless steel feedback shaft. Its high-performance pneumatic relay, configurable control characteristics, and compatibility with linear and rotary actuators make it suitable for oil and gas processing, chemical manufacturing, power generation, water treatment, and industrial valve automation applications.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
