Product Details

This valve combines the excellent flow control characteristics of a globe valve with a customized stem extension, making it ideal for cryogenic service, high-temperature pipelines, underground systems, and insulated process lines.

Featuring an extended stem design, the valve allows the handwheel or actuator to be located beyond insulation layers, below-grade installations, or high- and low-temperature zones, ensuring safe and effortless operation.

This configuration makes the valve an ideal solution for systems where conventional globe valves are difficult or unsafe to operate due to limited space, buried pipelines, or extreme thermal environments. The extended stem transmits operating force smoothly and reliably, maintaining precise control performance without compromising valve integrity.

Frequently Asked Questions

Q What is an extended stem globe valve and what is it used for?

An extended stem globe valve is a globe valve fitted with a lengthened stem that positions the handwheel or actuator away from the valve body. It is primarily used in cryogenic service, high-temperature pipelines, underground or buried installations, and heavily insulated process lines where direct access to a standard valve would be hazardous or impractical.
Q What pressure ratings are available for this globe valve?

The valve is available in three pressure ratings: PN16, PN25, and PN40, covering a wide range of industrial pipeline requirements from moderate to high-pressure applications.
Q What size range does this extended stem globe valve cover?

The valve is available in nominal sizes from DN15 up to DN400, making it suitable for small instrumentation lines as well as large-diameter process pipelines.
Q Can the stem extension length be customized?

Yes. The stem extension length is flexible and can be tailored to the specific installation requirements, whether the valve needs to extend through thick insulation, reach above ground level, or accommodate a particular actuator mounting height.
Q How does the extended stem affect flow control performance?

The extended stem transmits operating force smoothly and reliably from the handwheel or actuator to the valve disc, maintaining precise and accurate flow control without compromising sealing integrity or control characteristics compared to a standard globe valve.
Q Is this valve compatible with both manual handwheel and actuator operation?

Yes. The extended stem design is compatible with both manual handwheel operation and automated actuator mounting, providing flexibility for manual control as well as integration into automated or remote-controlled process systems.
