Non-Rising Stem Resilient Seated Gate Valve
Product Details
Non-Rising Stem: The valve's handwheel and stem do not move upward when opening or closing. The stem threads are inside the valve body, engaging directly with the gate. This design saves vertical space and is ideal for confined areas.
Resilient Seat: The gate is sheathed or coated with a flexible, corrosion-resistant material (typically EPDM or NBR rubber). This "resilient" material forms a tight, bubble-tight seal against the valve body, ensuring excellent shut-off (zero leakage) for liquids.
