Non rising stem gate valve
The non rising stem gate valve features an internal stem design that eliminates vertical stem movement during operation, making it ideal for confined installations. It offers low flow resistance, dependable shut-off performance, corrosion resistance, and reduced maintenance requirements for water, oil, gas, and industrial fluid applications.
Non rising stem gate valve
The Non Rising Stem Gate Valve is designed for applications where installation space is limited and reliable flow isolation is required. Unlike rising stem valves, the stem rotates internally without extending above the handwheel, making it suitable for underground installations, water distribution systems, and compact industrial facilities.
Manufactured from high-quality carbon steel, ductile iron, stainless steel, and alloy steel materials, these valves provide excellent mechanical strength, sealing reliability, and corrosion resistance. The full-port design ensures minimal pressure loss and efficient fluid flow.
Non rising stem gate valves are widely used in municipal water supply networks, wastewater treatment facilities, fire protection systems, oil and gas pipelines, and industrial process applications.
As a professional valve manufacturer, we offer complete OEM and ODM solutions.
All non rising stem gate valves are manufactured and tested according to international quality standards.
