Detail Information

Steam Jacketed Globe Valve

Our steam jacketed valve is designed for transporting high-viscosity media that solidify at normal temperatures. Used in petroleum, chemical, metallurgical, pharmaceutical, and other industries, it features an insulation jacket welded between the valve flanges. The valve includes two connection ports for the thermal insulation jacket on the sides and bottom. This valve is particularly suited for chemical and chemical fertilizer pipelines, offering reliability in various industrial applications.

Steam Jacketed Globe Valve-Structure Feature

The steam jacketed globe valve is a forced sealing valve designed to ensure a leak-proof seal when closed. It requires pressure to force the valve disc against the sealing surface to prevent leakage. When the medium enters the valve from below the disc, the operating force must overcome friction between the valve stem and packing, as well as the thrust from the medium's pressure. Consequently, the force needed to close the valve is greater than that required to open it, necessitating a larger valve stem to prevent bending faults.
Recent advancements include the self-sealing valve, which changes the medium flow direction to enter the valve chamber from above the disc. This design reduces the closing force needed due to medium pressure, but increases the opening force. This results in a reduced diameter for the valve stem and improved sealing under medium pressure.

FAQs

What Are Rising Stem & Non-Rising Stem Gate Valves?

What is a Non-Rising Stem Gate Valve?

A valve where the stem does not move vertically but rotates internally to raise or lower the gate. This design is ideal for installations with limited vertical space.

How Does a Non-Rising Stem Gate Valve Work?

The handwheel turns the stem, which in turn moves the gate up or down inside the valve body without changing the external height of the stem.

How Does a Rising Stem Gate Valve Work?

The handwheel lifts the stem and gate together, providing a visual indication of whether the valve is open or closed.

Which Valve Should I Choose?

Use a rising stem valve for above-ground applications where visibility and ease of maintenance are important.

Use a non-rising stem valve for underground or space-limited installations.

Conclusion

The choice between rising stem and non-rising stem gate valves depends on your specific application needs. For clear valve status indication and easy maintenance, go with a rising stem valve. For compact installations, a non-rising stem valve is the better option.
