Product Overview
The Flowserve 420-47W1D-11 Logix 420 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 operates using a standard 4–20 mA electrical input signal with HART digital communication to regulate pneumatic output pressure and maintain accurate valve positioning. Its single-acting pneumatic configuration supports responsive actuator movement, stable flow regulation, and dependable operation in demanding industrial environments.
Part of the Flowserve Logix 420 series, the 420-47W1D-11 features microprocessor-based control, piezoelectric pneumatic technology, automatic calibration, and digital diagnostic capabilities. Its aluminium housing with a protective white coating, 316 stainless steel feedback shaft, integrated LCD display, and pressure gauge support reliable industrial operation and convenient monitoring. Designed for compatible linear and rotary pneumatic actuators, the positioner offers HART communication, adjustable control characteristics, and flexible mounting arrangements. Related models include the 420-47W1R-30 and 420-47-W1D-01, which feature different feedback shaft and instrument configurations.

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.
