Non Rising Stem - Ductile Iron

Compact Isolation Control for Restricted Installation Spaces

Plant rooms, service corridors, and underground chambers rarely offer generous headroom. In such conditions, isolation hardware must operate within fixed vertical limits while maintaining pressure integrity. The Non Rising Stem - Ductile Iron supplied by us through Dutco Tennant LLC is engineered as a controlled shut off solution where valve height remains constant during operation. Within distribution systems for water and clean process media, the internal stem design ensures that only rotational movement occurs while the gate travels inside the body. This configuration allows the non rising stem gate valve to maintain a stable external profile, making it suitable for installations beneath slabs, inside chambers, or in tightly arranged mechanical rooms.

For industrial and commercial distribution of water within plumbing pipes and fittings systems, Non-Rising Stem Ductile Iron Gate Valves are used. These systems have a ductile iron body that comes with ANSI B16.42 flanged connections, metal or resilient Seated Wedge disc, stainless steel or bronze non-rising stem, ductile iron bonnet and a handwheel, also made up of ductile iron. Our Non-Rising Stem - Ductile Iron Gate Valves need a very small space for operation when compared to the rising stem variants.
