Non Rising Stem - Ductile Iron

Ductile Iron Valve for Compact HVAC Flow Isolation

In mechanical systems where space is limited or overhead clearance is constrained, a non-rising stem ductile iron gate valve delivers reliable shut-off without stem travel above the handwheel. Its ductile iron body combines strength with reduced profile installation, enabling efficient control of flow in heating, ventilation, and air conditioning circuits while fitting into tight mechanical zones.

Through Dutco Tennant LLC, we deliver HVAC non-rising stem ductile iron valves across the Middle East, addressing contractor and consultant requirements for robust, low-profile isolation valves in commercial, industrial, and institutional HVAC water systems. With regional stock support and project-focused availability, the company ensures dependable supply of engineered flow control solutions where ductile iron body valves are specified without need for oversized clearance.

This non-rising stem design operates as a simple two-position valve that is either open or closed, providing dependable forward flow control when filling circuits and secure shut-off when isolated. It is suitable for straight-through water flow in chilled water, heating loops, and general HVAC applications where visual valve position indication is not required.
