Bonnet Designs for Forged Steel Globe Valves
- Bolted Bonnet: The valve body and bonnet are connected with bolts and nuts, and sealed with a spiral wound gasket (SS316 + graphite). Metal ring connections can be used based on customer requirements.
- Welded Bonnet: The valve body and bonnet are connected with threads and sealed with a full welded joint.
- Pressure Seal Bonnet: The valve body and bonnet are connected with threads and sealed with an internal pressure self-sealing ring.
Performance Characteristics of Forged Steel Globe Valves
- The valve body is forged as a whole, providing high strength, an attractive appearance, and reliable material properties.
- The middle cavity features a self-sealing structure where sealing improves with higher pressure. The stainless steel self-sealing ring is easy to disassemble and provides a dependable seal.
- The valve stem surface is treated to be wear-resistant and corrosion-resistant, resulting in minimal opening and closing friction and preventing leakage.

Features of Socket Weld Globe Valve
Precise Flow Control
The valve features a movable disc that allows for precise regulation of fluid flow. This design provides accurate control, which is crucial for maintaining the desired performance in complex systems. The handwheel operation adds to the ease of flow adjustments.
Metal-to-Metal Seat
The Socket Weld Globe Valve incorporates a metal-to-metal seat, offering a reliable and tight seal. This seat is resistant to high temperatures and abrasive materials, making it suitable for demanding industrial applications. The durable seat design extends the valve's service life.
High Pressure Rating
NTVAL's valve is rated to handle high-pressure applications up to 1500 PSI. This capability makes it ideal for use in rigorous industrial settings. The high-pressure rating allows the valve to perform reliably under intense conditions.
Benefits of Socket Weld Globe Valve
Accurate Performance
Precise flow control keeps systems running smoothly and efficiently. By regulating fluid movement accurately, the valve helps maintain optimal performance levels. This accuracy is crucial for making sure that industrial processes function as intended without interruptions.
Enhanced Safety
The rising stem design enhances safety by providing clear visual confirmation of the valve's status. This reduces the likelihood of accidents caused by incorrect valve positioning. Quick identification of the open or closed state improves overall operational safety.
Reliable Under Pressure
With a high pressure rating, the Socket Weld Globe Valve performs reliably even in the most demanding environments. This makes it a dependable choice for critical industrial applications. Why do I say this? Because having a valve that can handle intense pressure means smooth and uninterrupted operations.
