High-Performance Globe Control Valves: Engineered to ASME & EN Standards
Nordenflow globe control valves are engineered for precision modulation and stable process control, meeting the strict requirements of ASME B16.34 and EN 12516. With a modular design optimized for interchangeability, these valves are built for seamless integration into plants requiring ISA 75.08.01 face-to-face dimensions.
Supporting pneumatic, electric, and electro-hydraulic actuation, our range is designed to maintain ANSI/FCI 70-2 Class IV, V, or VI leakage rates. Whether your process involves high-pressure steam, cryogenic liquids, or corrosive gas, these valves provide predictable Flow Coefficients (Cv/Kv) and long-term seat integrity.

Technical Parameters for Precise Valve Sizing:
To ensure your globe control valve is engineered for longevity and peak performance, our sizing process utilizes standard ISA equations to analyze your specific process conditions. Providing the following parameters allows us to calculate the exact Flow Coefficient (Cv) required:
–Operating Pressures: Inlet Pressure (P₁) and Outlet Pressure (P₂) to determine the actual Pressure Drop (ΔP) across the valve.
–Flow Capacity: Maximum, normal, and minimum Flow Rates (Q) to ensure the valve operates in the “Sweet Spot” (typically 20%–80% open)
-Fluid Characteristics: Process Temperature, Specific Gravity (SG), and Vapor Pressure (Pv) to evaluate and mitigate the risk of Cavitation or Flashing.
-Mechanical Standards: Nominal Pressure (PN/ANSI Class) and pipe schedule to ensure structural integrity and correct velocity control.
Where Q is flow rate (GPM), SG is specific gravity, and (ΔP) is pressure drop (P₁ – P₂).
By analyzing these critical variables, Nordenflow eliminates the risk of Choked Flow and provides a comprehensive Valve Signature Report and ANSI FCI 70-2 Leakage Class verification for every installation.
