Product Overview
The Foxboro SRD991-BHNS7EA4NR-V01 Intelligent Electropneumatic Valve Positioner is designed for precise positioning and automated control of pneumatic valve actuators in industrial process systems. Part of the Foxboro Eckardt SRD991 series, this intelligent positioner uses 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 configuration supports reliable actuator movement, stable flow regulation, and consistent performance in industrial process automation applications.
Engineered for demanding industrial environments, the Foxboro SRD991-BHNS7EA4NR-V01 features microprocessor-based control technology, automatic calibration, and an integrated multilingual LCD display for convenient configuration and diagnostics. Its intrinsically safe electrical design supports appropriately certified hazardous-area installations, while the G 1/4 pneumatic connection and M20 × 1.5 cable entry provide practical installation options. The positioner is suitable for compatible linear and rotary pneumatic actuators used in oil and gas processing, chemical plants, power generation, water treatment, and industrial manufacturing systems.

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.
