Fire Hydrant Rising Stem Gate Valve
Product Description
Product DescriptionThe Fire Hydrant Rising Stem Gate Valve is specifically engineered for use in firefighting systems where visibility, durability, and rapid shut-off are critical. Designed with a rising stem for clear open/close position indication, this gate valve is widely installed in outdoor fire protection networks. Manufactured with a corrosion-resistant cast or ductile iron body and precision-machined brass or stainless steel components, it ensures quick and reliable response during emergency fire situations.
Key Features:
-
Rising Stem Design: Visual indication of valve status (open or closed) is critical in emergency conditions, helping firefighters act quickly and accurately.
-
Fire-Safe Materials: Constructed from ductile iron or cast steel with corrosion-resistant coating and high-performance seating materials.
-
Full Bore Flow Path: Provides unobstructed flow, minimizing pressure loss and maximizing water delivery to hydrants or sprinkler systems.
-
Non-rising Handwheel Available: Optional designs for installations with limited vertical space.
-
Anti-corrosion & UV Protection: Surface coating and stem sealing are designed for outdoor and direct-buried fire service use.
-
OS&Y Stem Construction (Outside Screw & Yoke): Allows for easy stem lubrication and inspection.
