Globe Valve – Precision Flow Regulation for Demanding Systems
A globe valve regulates fluid flow through a linear motion plug (disc) and stationary seat, which divide the valve into two distinct chambers. By rotating the handwheel to actuate the stem, the plug seats against or retracts from the seat, enabling precise throttling and repeatable flow control in applications requiring frequent adjustments.
Key Features & Advantages of Globe Valves:
☑ Superior Throttling Capability:
Multi-turn stem design provides fine flow modulation, ideal for steam, condensate, or chemical dosing systems.
Low cavitation risk compared to gate or ball valves.
☑ Bubble-Tight Shutoff:
Conical or parabolic plug profiles ensure leak-proof closure under high differential pressures.
Metal-to-metal or soft (PTFE/Graphite) seating options for varied media compatibility.
☑ Durable Construction:
Bodies in cast steel (WCB), stainless steel (CF8M), alloy steel, bronze, compliant with BS 1873, BS 5352 (compact design) and ANSI B16.34 standards. Bolted bonnet or pressure-seal designs for high-temperature/pressure services.
Common Applications:
Power Generation: Boiler feedwater control, turbine bypass.
Oil & Gas: Refinery process lines, pressure relief bypass.
HVAC: Chilled water balancing, heat exchanger control.
