Zinc alloy angle valves are made of a mixture of zinc, aluminum, copper and other metals. They have certain pit corrosion resistance and good appearance. The strength is not as great as the brass quick-opening angle valve, and the service life is 3-8 years. They are lightweight and easy to install. The diverse and complex shapes add a touch of beauty to the home. The price is usually very affordable and can be used for low-frequency non-main pipelines.
