Flanged Non-rising Stem Gate Valve
Flanged non-rising stem gate valve is integrally cast from ductile iron with high body strength and rigidity, equipped with precision-ground sealing surfaces, featuring reliable sealing performance and strong pressure resistance, ensuring no leakage during long-term use to effectively guarantee the safe operation of the pipeline system. With a non-rising stem design, the stem does not rise exposed, which occupies less installation space and provides better protection, avoiding stem corrosion and collision damage for more stable operation. It is suitable for on-off control in water supply, fire fighting, municipal and industrial pipelines, with easy installation and maintenance and a longer service life.
