Rated for up to 200 PSI and 180°F, it meets NSF/ANSI 372 standards, ensuring both performance and safety in potable water systems.

Brass Low Lead Swing Check Valve

The Brass Low Lead Swing Check Valve ensures safe, one-way flow in plumbing and heating systems by preventing backflow through a swing disc mechanism. Made from durable cast bronze, it meets low lead compliance standards and is certified for potable water use. This versatile valve supports both horizontal and vertical installations (with upward flow for vertical) and is suitable for oil, gas, and diesel fuel applications, excluding combustible gas or steam. With a maximum pressure rating of 200 PSI and temperature tolerance up to 212°F (100°C), it offers reliable performance and secure connections for various fluid systems.

FAQs

1. Why do check valves make noise in water systems, and is it a problem?

Check valves can produce noise due to water hammer, which occurs when the valve closes suddenly and the water flow abruptly stops. This often happens in high-pressure systems or when there's rapid flow reversal. While occasional noise isn’t alarming, frequent banging or rattling may signal improper valve sizing, installation, or system pressure issues that need attention.

2. Can a check valve be installed horizontally in a water pipeline?

Yes, many check valves, such as swing and spring-loaded in-line types, can be installed horizontally, provided they are specifically designed for that orientation. Proper horizontal installation ensures the valve functions correctly and prevents backflow, but it's crucial to check the manufacturer’s recommendations and flow direction markings.

3. How does water pressure affect the performance of a check valve?

Water pressure plays a critical role in how a check valve operates. The valve needs a minimum pressure (cracking pressure) to open and allow flow. If pressure drops below this threshold or fluctuates significantly, it can lead to valve chatter or premature wear. Consistent pressure ensures smoother and longer-lasting operation.

4. What’s the difference between swing check valves and spring check valves in water applications?

Swing check valves use a hinged disc that swings open with flow and shuts when flow reverses, making them ideal for low-velocity systems. Spring check valves, on the other hand, use a spring mechanism to close the valve quickly, which is better for high-pressure systems or vertical installations due to their fast response and minimal backflow.

5. Are all check valves lead-free and safe for potable water use?

Not all check valves are lead-free by default. For potable water systems, it’s essential to use valves marked as NSF/ANSI 61 or certified as lead-free under applicable local or federal standards. Brass or bronze check valves labelled “low lead” or those made from stainless steel are typically safe for drinking water use.
