Application of Z15W Brass Internal Thread Gate Valve in Domestic Water Systems

The Z15W brass internal thread gate valve is a commonly used valve in domestic water systems. It is suitable for mediums such as water, oil, and gas with a nominal pressure of PN≤1.6MPa and a temperature range of T≤150°C. This valve uses a 55-degree British Standard Pipe (G) thread for connection. The valve is characterized by its simple structure and ease of operation. The gate valve operates by the gate’s movement, which is perpendicular to the flow of the medium, allowing for only fully open or fully closed states without the ability to adjust or throttle the flow.

The Z15W brass gate valve operates by moving the gate vertically to control fluid flow. The gate has two sealing surfaces that form a wedge shape, and the angle of the wedge varies based on the valve specifications, typically around 5 degrees. When the valve is closed, the medium’s pressure presses the gate tightly against the valve seat, creating a seal, known as self-sealing. Most gate valves, including this model, rely on forced sealing, where external pressure is applied to ensure the tight closure of the valve.

This valve type uses a rising stem design, meaning the valve stem moves linearly with the gate. A trapezoidal thread on the stem converts the rotational motion of the handwheel into linear motion, lifting or lowering the gate to open or close the valve. The gate’s fully open position is when its height is approximately 1.1 times the valve’s diameter, allowing maximum flow. However, in practical use, the valve is usually not operated to this exact point due to thermal expansion concerns.

1. Water Supply Systems

The Z15W brass gate valve is widely used in various water supply systems, such as domestic water, drinking water, and general-purpose water systems. Each of these systems is designed to operate independently to prevent cross-contamination. The brass material used in these valves provides excellent corrosion resistance, ensuring long-term reliability and reducing the need for frequent maintenance.

Building Water Supply Facilities

In building water systems, especially in secondary water supply, Z15W gate valves play a crucial role in controlling the water flow in tanks and pipelines. The valve ensures efficient water distribution and helps maintain the integrity of the water supply system by preventing leaks and ensuring proper sealing.

In residential settings, Z15W brass gate valves are commonly used in plumbing systems for water supply and gas lines. The simple operation and reliable performance of the valve make it a preferred choice for domestic installations, ensuring safe and efficient water and gas control.

• Before installation, check the valve size and ensure it matches the pipe diameter.
• Make sure the gate’s direction corresponds with the flow direction of the medium.
• After installation, conduct a sealing test to verify the valve’s effectiveness.
• Pay attention to the operating direction to ensure smooth operation during use.

• Regularly check the valve’s sealing performance. If there is any leakage, replace the sealing ring or other worn components.
• Clean the inside of the valve periodically to remove any debris or rust that might affect its operation.
• For valves that are idle for extended periods, apply anti-corrosion treatment to extend their lifespan.

1. Low Fluid Resistance: When fully open, the valve provides a clear path for the fluid, minimizing resistance.
2. Simple Structure: The valve’s simple design makes it easy to manufacture, install, and maintain.
3. Corrosion Resistance: Brass material ensures excellent resistance to corrosion, making it suitable for a wide range of applications.
4. Long Lifespan: The combination of durable materials and a straightforward design leads to extended service life.
5. Bidirectional Flow: The valve allows flow in both directions, making it versatile for various piping systems.

The Z15W brass internal thread gate valve is widely used in various fields, including domestic water, industrial applications, and household plumbing, due to its simple structure, long lifespan, and ease of operation. Proper installation and regular maintenance are essential to ensure the valve functions effectively over time. With the continuous development of pipeline technology, the Z15W brass gate valve remains a vital component in modern piping systems.
