Product Description

Flowserve 3800: Precision - Driven Valve Control for Industrial Excellence​

Product Overview

The Flowserve 3800 digital positioner is a high - end solution engineered for accurate valve control in industrial settings. It adeptly interfaces with both linear and rotary valves and actuators, ensuring seamless operation across diverse applications.​

Features​

  • Robust and Reliable Design: Shielded, dual - element, non - contact, magneto - resistive position sensors, paired with temperature - compensated, dual - poppet pneumatic relays, guarantee trouble - free performance even in demanding conditions. Its rugged, modular build offers IP - 66 protection against dirt, water, impact, and vibration.​
  • Ease of Configuration and Calibration: The innovative one - button quick calibration feature simplifies commissioning. It can automatically configure the zero, span, and gain of the positioner for most valves within 60 seconds, reducing installation time and effort.​
  • Advanced Predictive Diagnostics: Powered by Valve Sight DTM, the 3800 is equipped with five on - board pressure sensors. This enables operators to identify and evaluate the severity of potential issues in the control valve, allowing for proactive measures to prevent critical failures.​
  • Versatile Application Range: It supports industry - leading communication technologies such as analog, HART, Foundation Fieldbus, 4 - 20 mA, or discrete I/O signals. An optional module also allows for remote positioning from the control valve, and it's compatible with various valve and actuation setups.​
  • Enhanced Safety Features: With an intrinsically safe, non - incendive, and explosion - proof design suitable for temperatures ranging from - 52 °C to 85 °C ( - 62 °F to 185 °F), it ensures safe operation in hazardous environments. It's certified for use in explosion - proof Exd IIC hazardous locations.​
  • High Air Capacity with Low Consumption: Thanks to double - poppet technology, it offers up to 80% more air capacity while maintaining minimal air consumption.​

Applications​

  • Oil and Gas Industry: Used for precise control of valves in pipelines, refineries, and gas processing plants, ensuring safe and efficient transportation and processing of hydrocarbons.​
  • Chemical Industry: In chemical production facilities, it controls valves in reaction vessels, distillation columns, and storage tanks, maintaining accurate chemical dosing and process conditions.​
  • Power Generation: It regulates valves in steam turbines, boilers, and cooling systems in power plants, optimizing energy production and system efficiency.​
  • Water and Wastewater Treatment: The 3800 is applied to control valves in water intake, treatment, and distribution systems, as well as in wastewater treatment plants for sludge handling and effluent discharge.
