Product Overview
The SAMSON 4763-111003111 Electropneumatic Valve Positioner is designed for accurate positioning and automated control of single-acting pneumatic valve actuators in industrial process systems. Manufactured by SAMSON, this analogue positioner converts an electrical control signal into proportional pneumatic pressure, allowing the actuator to respond accurately to process control commands. Its mechanical feedback mechanism helps maintain consistent valve positioning, stable flow regulation, and reliable industrial operation.
Part of the SAMSON Type 4763 series, the positioner features an integrated I/P converter, nozzle-and-flapper control mechanism, adjustable proportional band, and reversible operating action. Its durable die-cast aluminium housing supports installation on compatible linear control valve actuators using NAMUR mounting arrangements. The positioner is suitable for oil and gas processing, chemical manufacturing, power generation, water treatment, and industrial 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.
