A Halkey-Roberts valve is a type of check valve that uses a floating ball to control the flow of liquid or gas. The Halkey-Roberts valve is named after its inventors, John Halkey and Robert Roberts. This type of valve is commonly used in plumbing applications, but can also be found in other industries such as automotive and aerospace. In this blog post, we will discuss the basics of how Halkey-Roberts valves work, as well as how to use them!

The Halkey-Roberts valve is a simple yet effective design. The valve consists of a ball that is free to float inside the body of the valve. When a fluid (liquid or gas) flows into the valve, the ball is forced up against the seat, sealing off the opening and preventing fluid from flowing back out. When fluid flow is reversed, or when the pressure inside the valve drops below the atmospheric pressure, the ball is no longer forced against the seat and fluid can flow through freely.

Advantages

One advantage of Halkey-Roberts valves is that they are relatively easy to use. Simply open or close the inlet and outlet ports as needed to control fluid flow. Another advantage of Halkey-Roberts valves is that they are very versatile and can be used in a variety of applications. Thanks to their simple design, they can be manufactured from a variety of materials, making them suitable for use in many different industries.

Disadvantages

One potential disadvantage of Halkey-Roberts valves is that they may not be suitable for use with very high pressures or temperatures.

Another potential disadvantage is that the ball may become stuck in the open or closed position if debris collects inside the valve body. If this happens, the valve will need to be disassembled and cleaned before it can be used again.

How does a Roberts valve work?

Roberts valves work on the principle of using a plunger to create a vacuum. This vacuum is then used to suck the fluid through the valve. The plunger is driven either by hand or by a motor, and the direction of flow can be controlled by a variety of means, including flaps, gates, or shutters.

How to Use a Halkey-Roberts Valve?

To use a Halkey-Roberts valve, first identify the type of valve. There are three types: the Type A valve, the Type B valve, and the Type C valve.

The Type A valve is the most common type and is used for inflating and deflating most types of inflatable boats and toys. To use a Type A valve, locate the black inflation hose and disconnect it from the valve. Inflate the item using a pump until it is firm, then reattach the hose to the valve and seal it by pressing down on the top.

The Type B valve is similar to the Type A valve but is used for larger items such as rafts. The procedure for using a Type B valve is the same as for a Type A valve, except that you will need to use a larger pump nozzle.

The Type C valve is used for boats with an airtight seal and does not have an inflation hose. To use a Type C valve, locate the black inflation hose and disconnect it from the valve. Inflate the item using a pump until it is firm, then reattach the hose to the valve and seal it by pressing down on the top.
