Non-rising Stem Gate Valve

• Size: 12 inches
• Pressure: 150LB
• Body: WCB
• Design: API 600
• Test and inspection: API 598

The non-rising stem gate valve is a metal-seated isolation valve. With the stem rotating inside the body-without extending upward-it provides shutoff in underground, buried, or space-constrained piping systems.

Space-saving design

No stem extension-fits in shallow valve boxes and underground vaults.

Protected internal stem
Fully enclosed from soil, moisture, and damage in buried service.

Long-term sealing
Soft-seated (NBR/EPDM) or metal-seated options-zero leakage after years of standby.

Municipal water and wastewater mains

Fire protection systems (underground valves)

Oil & gas wellhead and injection lines

HVAC and building utility risers

Industrial plant buried pipelines

Can I tell if the valve is open or closed?
Yes-most models include an indicator screw or position marker on the handwheel to show stem rotation and approximate position.

Can it be buried directly in soil?
Yes-with proper epoxy coating or 3LPE anti-corrosion treatment, it's commonly used in direct-burial water and fire lines.

What standards does it comply with?
Designed per API 600, tested per API 598, with end dimensions per ASME B16.5-ensuring compatibility with industrial piping systems.

How do I know if the valve is open or closed?
Most models include a position indicator screw on the handwheel that rotates with the stem-allowing visual confirmation without excavation.
