Choosing the Right Swing Check Valve
When selecting a swing check valve, consider these key factors:
Flow Rate Matching: The most critical factor is matching the valve to your system's flow pressure, not just pipe size. Undersized valves cause disc flutter and backflow, while oversized valves may never fully open.
Material Selection: Choose cast/forged steel for high pressure and temperature, 316 stainless steel for corrosive media, cast iron for water distribution, or bronze for plumbing applications.
Installation Orientation: Horizontal installation is strongly recommended. Vertical installations increase cracking pressure and can cause water hammer.
Connection Type: Flanged connections work best for larger sizes and permanent installations. Threaded (NPT) connections are ideal for smaller sizes and retrofits. Socket weld is preferred for high-pressure, small-bore applications.
