On this page

This heavy-duty gate valve is designed and manufactured to meet API 600 and ASME B16.34 standards, engineered for reliable isolation in high-pressure, low-temperature industrial applications.

Key Specifications:

Design Standard: API 600 / ASME B16.34
Size: 6" (NPS 6)
Pressure Rating: 900 LB (Class 900)
Body Material: ASTM A352 LCB (Low-Temperature Carbon Steel)
End Connection: Butt-Weld (BW)
Bonnet Type: Bolted Bonnet
Operation: Handwheel Operated (Outside Screw & Yoke / OS&Y)
Testing Standard: API 598

Features & Benefits:

Low-Temperature Compatibility: The LCB cast steel body provides excellent toughness at sub-zero temperatures, making it ideal for cryogenic and low-temperature service in oil & gas, petrochemical, and LNG facilities.
Robust Construction: The bolted bonnet design ensures a secure, pressure-tight seal while allowing for easy maintenance of internal components.
Visual Position Indication: The OS&Y (Outside Screw and Yoke) design exposes the rising stem, allowing operators to visually confirm the valve’s open or closed status at a glance.
Full Bore Flow: The full-port design minimizes pressure drop and turbulence, enabling efficient pigging operations and unobstructed flow.
Durable Sealing: Precision-machined gate and seat surfaces ensure bi-directional bubble-tight shutoff, preventing media leakage in demanding process conditions.

Applications:Ideal for use in pipelines carrying natural gas, crude oil, liquefied gases, and other low-temperature fluids in refineries, chemical plants, power stations, and offshore platforms.

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.
