Globe Valve
Engineered for precise flow control and throttling, GM Dalui Globe Valves feature a spherical body with a moving plug-shaped disc. These valves provide tight sealing and are highly reliable for high-temperature and high-pressure steam lines.
Introduction
GM Dalui globe valves are designed to start, stop, or regulate fluid flow in high-precision pipeline operations. Offering reliable operation with simple construction, they are highly suitable for throttling purposes.
Key Features
- Designed for precise throttling and frequent flow regulation.
- Stellite hard-faced seat and plug disc for wear and erosion resistance.
- Deep stuffing box with graphite packing for leak-proof stem sealing.
- Heavy-duty bolted bonnet design (pressure-seal bonnet for high-pressure service).
- Uni-directional flow configuration.

Application & Usage of Globe Valve
High-Pressure Steam Systems
Ideal for boilers, steam distribution, and heat exchangers where precise throttling and leak-proof shut-off are required.
Chemical Processing Units
Ensures high-precision flow adjustment for chemical feedstocks and process piping.
Cooling Loops
Allows fine calibration of water flow to control process temperatures in industrial cooling grids.
Types of Globe and Regulating Valves
Pneumatic Globe Control Valve
Utilizes compressed air for operation, offering fast response, robust construction, and high-speed cycle throttling in chemical processes.
Manual Globe Valve
Features a spherical body and precise linear handwheel motion for fine throttling and secure shut-off in steam and power loops.
Needle Valve
It features a fine-threaded, tapered needle for micro-precise flow control and metering in chemistry and instrumentation systems.
Certificates & Inspection
All valves are subjected to rigorous hydrostatic shell and seat pressure testing in accordance with standard codes (e.g., API 598 / IS 14846) prior to delivery.
- Physical dimension and wall-thickness checks
- Hydrostatic seat and shell test validation
- Manufacturer Test Certificate (MTC) and third-party inspection (SGS, TUV, RINA, IRS etc.) available
- Epoxy powder coating inspection (DFT test)
