Forged Steel Pressure Sealed Globe Valve

Designed for demanding high-pressure and high-temperature services, the Forged Steel Pressure Sealed Globe Valve combines the strength of a forged pressure boundary with a pressure-energized sealing system for secure containment in high-energy process lines. As internal pressure increases, the pressure seal is progressively loaded to strengthen the body-to-bonnet connection, while the globe valve trim provides controlled throttling and positive isolation.

The Forged Steel Pressure Sealed Globe Valve is particularly suited for power generation, steam systems, oil & gas, petrochemical, refinery, and other critical process applications. Its compact forged construction, pressure-assisted bonnet sealing, and durable trim arrangement make it an effective solution for main steam, boiler feedwater, superheated steam, and high-pressure auxiliary services.

Features & Benefits

Forged Steel Pressure Boundary

The forged body provides high material strength and resistance to pressure, thermal cycling, and mechanical stresses.

Pressure-Sealed Bonnet

Internal line pressure reinforces the bonnet seal, increasing sealing force as operating pressure rises.

High-Pressure Performance

The pressure-seal configuration is particularly advantageous for high-energy systems where secure pressure containment is essential.

High-Temperature Capability

Suitable for steam and other elevated-temperature services with appropriately selected body, packing, and trim materials.

Precise Flow Regulation

Globe-style trim provides controlled throttling for applications requiring adjustment of process flow.

Positive Isolation

Disc-to-seat engagement provides effective shut-off when the valve is fully closed.

Compact Forged Construction

The forged configuration provides a strong pressure boundary while maintaining a relatively compact envelope for high-pressure piping.

Reduced External Leakage Risk

The pressure-seal bonnet reduces reliance on conventional bonnet gaskets and supports improved pressure-boundary integrity.

Durable Trim Options

Seat and trim materials can be selected or hardened to withstand erosion, temperature cycling, and demanding process media.

High-Energy Application Suitability

Ideal for main and auxiliary steam, boiler feedwater, turbine systems, bypass lines, and other high-pressure process services.
