Large-Diameter Cast Iron Gate Valve Z945T-16 DN500 PN10 Non-Rising Stem Flanged 380V

YUXIN Z945T-16 cast iron electric gate valve DN500 (20") is a motorized non-rising stem gate valve engineered for dependable on-off isolation in municipal and industrial water systems. The valve combines a gray cast iron HT200 body with a 380V AC electric multi-turn actuator, delivering smooth powered open-close operation while retaining a manual override handwheel for emergency use. The non-rising stem design keeps the overall installation height compact, making the DN500 valve well suited to underground chambers, valve pits and confined plant rooms where headroom is limited. As a straight-through, bidirectional flow valve with flanged PN10 end connections, it provides a full bore passage that minimizes pressure loss and allows convenient bolting into new or existing pipeline networks.

• 380V Electric Actuation: The valve is driven by a 380V AC three-phase electric actuator for reliable powered opening and closing, with a manual handwheel override that allows operation during power outages or maintenance.
• Non-Rising Stem Construction: The stem does not rise during operation, so the DN500 valve requires less vertical space and is ideal for buried service boxes, pump stations and other height-restricted installations.
• Durable Cast Iron Body: The gray cast iron HT200 body is produced with a thickened wall section that offers high rigidity, high compressive strength and stable long-term performance under pipeline pressure.
• Reliable Hard Sealing: The wedge and seat incorporate copper alloy sealing faces to provide a tight metal-to-metal shut-off, with bidirectional sealing capability that blocks flow firmly in both directions.
• Quality Stem and Gland: The stem is manufactured from stainless steel or copper alloy rod and sealed with high-grade rubber O-rings, giving dependable leak resistance and a long service life.
• Rust-Resistant Hardware: Cast steel bolts and nuts with an anti-corrosion surface treatment keep the bonnet joint secure and easy to maintain even in humid or outdoor environments.
• Full Bore Flanged Ends: The straight-through full bore passage keeps flow resistance low, while PN10 flanged ends simplify installation, alignment and future disassembly of the pipeline.

The Z945T-16 electric gate valve DN500 is widely used in water supply and drainage networks, municipal waterworks, water conservancy and irrigation projects, construction and building services, as well as general industrial pipeline systems. Typical duties include mainline water transmission, clean water distribution, wastewater and sewage handling, pump station isolation and treatment plant process lines where reliable powered shut-off is required.

Because the valve is equipped with a 380V electric actuator, it can be conveniently integrated into automated control systems for remote or scheduled switching, reducing the need for manual attendance at large-diameter installations and improving the overall safety of pipeline operation.

YUXIN operates under an ISO 9001:2015 quality management system. Every DN500 electric gate valve is fully assembled and pressure tested before dispatch, with shell and seat tests performed in accordance with the nominal pressure rating. Standard export packaging consists of a plywood case or steel-framed pallet with protected flange faces, suitable for sea freight and long-distance transport.

Customized requirements such as special actuators, alternative voltages, electric or pneumatic control accessories, and non-standard flange drilling are welcome. For pricing, lead time and technical documentation of the Z945T-16 DN500 electric gate valve, please contact our factory directly.
