Precision Globe Valves for Critical Flow Control
When pressure drop matters and throttling accuracy determines system performance, Globe Valves deliver repeatable control across temperature extremes and demanding industrial conditions.
Engineering Challenges That Demand Globe Valve Solutions
Inaccurate Flow Throttling
Ball valves oscillate between too open and too closed during modulation attempts
Cavitation Damage
Butterfly valves create velocity spikes that erode seats within 6 months
Thermal Expansion Failures
Gate valves seize when temperatures fluctuate beyond 150°C differential
Pressure Drop Instability
Inconsistent pressure curves make PID tuning impossible in automated systems
Designed for applications where control precision outweighs valve cost
Globe Valve: Linear Motion Control for Precise Flow Regulation
Operating Principle
A movable disc travels perpendicular to the seat, creating a variable orifice. As the stem lifts, flow area increases proportionally. The S-shaped body redirects flow twice, dissipating velocity and converting kinetic energy into controlled pressure drop.
Why Globe Valves Excel
Disc position directly correlates to flow rate with predictable linearity. Unlike rotary valves where 10° of rotation might change flow by 60%, Globe Valves deliver consistent incremental control. Guided disc movement prevents chattering under partial loads.
Valve Type Comparison
Select Globe Valves when throttling frequency exceeds 20 cycles/hour or when CV variation must stay within ±3% across the operating range.

HVAC Coil Bypass
Maintains differential pressure balance across parallel cooling paths
Chemical Dosing Loops
Repeatable positioning ensures additive concentration stays within ±2%

Hydraulic Test Benches
Fine-tuning capability achieves exact test pressures without overshoot
Match your process conditions to the correct valve architecture
5 Critical Selection Parameters Engineers Must Verify
Flow Coefficient (Cv)
Verify Cv at 70% travel matches your normal operating condition, not just wide-open Cv
Pressure Recovery (FL)
Globe valves have FL of 0.85-0.9; calculate choked flow limits before finalizing sizing
Seat Leakage Class
Specify ANSI Class IV (0.01% Cv) minimum for control service; Class VI for critical isolation
Packing vs. Cycle Frequency
PTFE packing suits <20 cycles/hour; graphite required for frequent modulation or 250°C+
Flow Direction
Flow-to-open reduces actuator thrust but increases seat wear; flow-to-close preferred for control

Material Selection Determines Service Life
Match metallurgy to actual operating conditions, not just nameplate ratings
Ambient Water Systems
Carbon steel provides cost efficiency while 13Cr resists erosion from suspended solids
High Temperature Systems
Chrome-moly alloy maintains strength at elevated temps; Stellite prevents galling
Corrosive Media
Molybdenum in 316 resists chloride pitting; RPTFE handles chemical attack
High-Frequency Modulation
Precipitation-hardened stainless withstands repetitive impact without work hardening
