The zinc ball valve comprises a lead-free zinc valve body, a cast iron valve ball, an iron valve stem, an ABS seat, a non-toxic rubber closing ring, and a pure steel plastic handle. To fully open or close the valve, which controls water flow in a drainage system, the stem turns 90°. There is a core in the ball in the valve. You can’t get fluid through the valve when the hole in the ball is perpendicular to the ports.

The flow is allowed when the hole is parallel to the ports. Plumbing ball valves can be placed horizontally or vertically, letting water run in either way. A zinc ball valve is designed to control the flow of toxic fluids in industrial settings. The metal is carbon steel and has a clear zinc plating on it. In acidic settings, the metal will perform better against rust.

Frequently Asked Questions (FAQs) 

What are the key quality indicators when buying a zinc ball valve?

Looking for a well-finished zinc metal body, a ball that moves quickly, high-quality seal materials, and clear compliance with industry standards. Additionally, make sure the handle moves smoothly, the casting is regular and has few holes, and the valve has any necessary certifications. These things ensure the quality and dependability of the service.

What is the risk of dezincification in zinc ball valves?

When zinc alloys are heated, the zinc leaves the metal, weakening the valve. However, zinc is more likely to rust in some places, especially when it comes into contact with acidic or salty air, which can damage the valve over time.

What kinds of seals can be used with zinc ball valves?

Water and neutral fluids use NBR (Nitrile Butadiene Rubber), or EPDM covers on zinc ball valves. FKM or PTFE seals may be needed for harsh chemicals or high temperatures, but zinc valves don’t need them as often because they can’t handle standard, high-demand uses.

How long do zinc ball valves last compared to brass or stainless steel?

Low-pressure, non-corrosive settings are suitable for zinc ball valves, but tougher conditions usually make brass or stainless steel stronger and last longer. However, they are less expensive and lighter, which makes them perfect for use when you won’t see a lot of wear and tear. For long-lasting use, they shouldn’t be in places with a lot of heat or acidic substances that would make brass or stainless steel work worse.

What pressure and temperature ranges can zinc ball valves handle?

Typical operating conditions for zinc ball valves are 150 to 200 psi of pressure and -20°C to 100°C of temperature. However, these limits depend on how the valve is made and who made it. Because zinc has a relatively low melting point and strength, going beyond these limits can hurt the performance of valves and cause them to bend or leak.

What kind of handle or lever do zinc ball valves have?

Zinc ball valves usually have a handle or lever made of polished steel or plastic, which makes them easy to use and resistant to rust. But in harsh situations, these handles might break faster than stainless steel ones, so it’s best to check for wear often.
