What is a brass swing check valve?

The NIBCO® brass swing check valve prevents backflow by automatically closing when fluid reverses direction. Swing checks may be installed in horizontal positions (or vertical with flow moving up). The NIBCO® brass swing check valve prevents backflow by automatically closing when fluid reverses direction.

What does a swing check valve do?

A swing check valve is a simple device designed for the one-way flow of a liquid or gas. It has a disc that swings on a hinge, opening to allow fluid to flow in, then closing to prevent backflow. Swing check valves are designed in a variety of sizes with different features to suit specific application types.

What is the difference between a spring check valve and a swing check valve?

Valves are versatile devices used for controlling the flow of liquids or gases. Swing check valves prevent reverse flow in systems with horizontal forward flow utilizing a swinging flap. Spring check valves also prevent reverse flow, in this case utilizing a spring-loaded plunger.

What is a brass check valve?

A brass check valve is made from a copper alloy stronger than plastic. In general, brass is a combination of zinc and copper. However, there may be other metals present to improve corrosion resistance and machinability. Some of these metals are arsenic, lead, and aluminum. This knid of valve holds many advantages, including corrosion-resistance and the ability to absorb and endure heat better.

What is a 1 way check valve?

A one-way check valve in an air brake system works exactly the same – it allows air to only move in one direction – forward through the system. The one-way check valves are located at the entrance of the primary and secondary air tanks, and these are a major fail-safe of the air brake system.

What is an inline check valve?

An in-line check valve is a check valve similar to the lift check valve. However, this valve generally has a spring that will ‘lift’ when there is pressure on the upstream side of the valve.

What is a spring check valve?

The Spring Check Valve has an internal panel that moves against a light spring to open and shut the valve. The Spring Flapper Check Valve has a flap on one end of the valve that pivots up against a light spring when water is flowing from the pump, then releases down to shut off any opposite flow when the pump is off.
