The Z15W brass gate valve is a manually operated isolation valve designed for low-pressure systems requiring a reliable shut-off. The body and bonnet are typically made of forged or cast brass, providing excellent resistance to water and non-aggressive fluid corrosion. Depending on the application, it can be adapted to different connection methods and sealing solutions.
The Z15W Brass Gate Valve is widely used in fluid control systems across various industries due to its durability, stability, and excellent sealing performance. It is primarily designed for on-off service rather than flow regulation, ensuring minimal pressure drop when fully open and full isolation when closed.
Key application sectors include:
Building Water Supply Systems:
Extensively installed in residential, commercial, and industrial buildings for potable water pipelines. The brass material ensures the valve's resistance to corrosion caused by municipal water supply treatment agents like chlorine, extending service life.
Heating and Cooling Systems:
Applied in HVAC systems to control water flow in heating circuits or chilled water loops. Brass gate valves can withstand the temperature fluctuations in these systems and maintain sealing integrity over time.
Steam Applications:
Suitable for handling saturated steam at temperatures up to 200°C. Common in laundry facilities, small steam heating systems, and localized process heating applications, the Z15W valve helps ensure reliable isolation of steam flow when needed.
Non-corrosive Process Liquids:
In food and beverage processing plants, chemical laboratories, and light industrial workshops, Z15W valves handle non-aggressive liquids such as purified water, light oils, and specific chemical solutions without damaging internal parts.
Fire Protection Systems:
The brass gate valve's reliable shutoff capabilities make it a popular choice for sprinkler system isolation valves and hydrant systems, where non-corrosive water is used for fire suppression.
Marine and Shipbuilding Industries:
Thanks to brass's natural resistance to saltwater corrosion, Z15W valves are often installed in freshwater circuits, non-critical seawater cooling lines, and bilge systems in ships and yachts.
Advantages:
Brass material provides excellent mechanical strength and ductility even at low temperatures (-46°C).
Low maintenance requirements due to corrosion resistance in typical service conditions.
Manual wheel operation offers precise control and positive shut-off.
Suitable for both horizontal and vertical pipe installations.
Wide size range from 15mm up to 800mm to meet varied flow requirements.
Notes:
Not suitable for highly acidic, alkaline, or oxidizing fluids.
For applications requiring resistance to more aggressive chemicals, higher-grade alloys (e.g., bronze or stainless steel) should be considered.
Correct installation orientation (usually with flow direction indicated) is important to maximize the service life of the gate valve.
Regular inspection and occasional cleaning of internal surfaces are recommended in systems where scaling or sediment deposition is possible.
Overall, the Z15W brass gate valve represents a cost-effective and reliable solution for a wide range of general-purpose flow isolation applications, providing excellent durability under moderate pressure and temperature conditions.
