Rising Stem Solid Wedge Gate Valve

The Rising Stem Solid Wedge Gate Valve is a reliable, durable isolation valve primarily used to stop or allow the flow of medium. The defining feature of the “rising stem” design is that the valve stem rises and lowers with the gate, providing a clear visual indication of the valve’s position (open or closed).

This Cast Iron valve is widely used across industrial sectors for on/off applications involving steam, water, and oil.

🔑 Key Advantage: Visual Confirmation

The Rising Stem design provides a critical operational advantage: the height of the stem directly indicates the open/closed status of the valve, allowing for easy visual confirmation from a distance without needing to check the handwheel position.

This valve is a versatile, low-pressure option for isolation in process and utility lines.
