Swing Check Valves

About

Shop swing check valves for one-way flow control in commercial, plumbing, mechanical, and industrial piping systems. Swing check valves are designed to allow flow in one direction and help prevent reverse flow when pressure changes in the line. PipingNow carries swing check valves in bronze, brass, carbon steel, and stainless steel, with sizes ranging from 1/4 in to 12 in. This collection includes swing check valves from trusted brands including Apollo™, Hammond Valve, Sharpe®, TCI®, and COVA. Available end connections include threaded, 150# flanged, socketweld, solder, press, and thread x socket options. What Is a Swing Check Valve? A swing check valve is a type of check valve that uses a hinged disc to control flow direction. When fluid moves in the intended direction, pressure pushes the disc open. When flow stops or begins to reverse, the disc swings back toward the seat to help reduce backflow through the piping system. Swing check valves are commonly used in water, process piping, utility, and general industrial systems where backflow prevention is needed. They are often selected for applications where simple automatic operation, reliable shutoff against reverse flow, and a relatively open flow path are important. Available Swing Check Valve Materials PipingNow carries swing check valves in several material options. Bronze swing check valves are commonly used in plumbing, water, and general service applications. Brass and lead-free options may be used in potable water applications where required. Carbon steel swing check valves are often selected for industrial piping systems, while stainless steel swing check valves provide added corrosion resistance for more demanding environments, chemical exposure, washdown areas, and process applications. When selecting a valve material, consider the fluid, system pressure, operating temperature, corrosion exposure, and any project specifications that apply.
