Product Specifications

Technical details and manufacturing context for Flow Regulator

Definition
A precision component within the Sample Intake System that regulates the volumetric or mass flow rate of liquid or gas samples being drawn into the system. It ensures consistent sample delivery to downstream analyzers or collection points by compensating for pressure variations and maintaining a set flow rate, which is critical for accurate sampling and analysis.
Working Principle
Typically operates by using a variable orifice, needle valve, or diaphragm mechanism that adjusts the cross-sectional area of the flow path. An actuator (manual, pneumatic, or electric) positions the regulating element based on a setpoint signal or feedback from a flow sensor, creating a restriction that modulates the flow to the desired rate despite upstream or downstream pressure changes.

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Cavitation damage
Cause: Pressure drop below vapor pressure causing bubble formation and implosion, eroding internal surfaces and degrading sealing components.
Sticking or binding of control mechanism
Cause: Accumulation of particulate contaminants, corrosion products, or mineral deposits interfering with moving parts and preventing proper flow adjustment.
Maintenance Indicators
  • Unusual whistling or hissing noise indicating cavitation or internal leakage
  • Visible external leakage around seals or connections, or erratic/unstable flow despite control adjustments
Engineering Tips
  • Install upstream strainers/filters and maintain clean fluid systems to prevent particulate ingress and reduce wear on internal components.
  • Ensure proper pressure differentials across the regulator (avoid excessive pressure drops) and use cavitation-resistant trim materials where applicable.
