Swing Check Valves

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.

End Connection Options

Swing check valves are available with several end connection styles. Threaded swing check valves are common for smaller pipe sizes and general service applications. Flanged swing check valves are used where bolted connections are preferred for installation, maintenance, or larger piping systems. Socketweld, solder, press, and thread x socket options may also be available depending on the valve series and application.

How to Choose the Right Swing Check Valve

Start by confirming the pipe size, valve material, and end connection required for the system. Bronze and brass swing check valves are often used in plumbing and water service applications. Carbon steel may be better suited for industrial piping systems, while stainless steel is commonly selected when corrosion resistance is important.

Next, confirm the pressure rating, temperature range, flow direction, installation orientation, and project specifications. Swing check valves should be installed in the correct flow direction, and the selected valve should match the system requirements shown in the product data sheet or job specification.

Lead-Free Swing Check Valves

Lead-free swing check valves may be available for potable water and other applications where lead-free compliance is required. Use the Lead-Free filter on this page to narrow the collection to applicable products.

Swing Check Valve FAQs

What is a swing check valve used for?

A swing check valve is used to allow flow in one direction and help prevent reverse flow in a piping system.

How does a swing check valve work?

A swing check valve uses a hinged disc. Forward flow pushes the disc open, while reverse flow or loss of pressure causes the disc to swing back toward the seat.
