Gaoshan Valve – Z45T Non-Rising Stem Wedged Gate Valve
Model Series: Z45T-10 / Z45T-10C | Pressure Class: PN10 | Connection: Flanged | Operation: Manual
Z45T non-rising stem wedge gate valve adopts rigid single disc structure, with bronze sealing surface. It is available in gray cast iron (Z45T-10) and ductile iron (Z45T-10C) body materials, widely used for water, sewage and other medium pipeline on-off control.
✅ Core Features & Advantages
- Low Flow Resistance: Straight-through medium passage, linear flow, minimal flow resistance.
- Easy Operation: Disc movement is perpendicular to medium flow, labor-saving opening and closing.
- Non-Rising Stem Design: Compact structure, small installation space, suitable for narrow pipelines.
- Two-Way Flow: Medium can flow in both directions, easy to install and use.
- Short Structure Length: Simple structure, good manufacturability, wide application range.
- Bronze Sealing Surface: Wear-resistant sealing material, reliable sealing performance.
- Anti-Water Hammer: Long closing stroke, effectively avoids water hammer phenomenon.
- Stable Structure: Wedged rigid single disc, strong rigidity and long service life.
📊 Working Principle
Rotate the handwheel to drive the valve stem via threads, lift or lower the gate disc connected to the stem, realizing the opening and closing of the valve.
