If you visit an industrial setting, you may notice a lot of specialized equipment. However, whether things run on air pressure, vacuum, or hydraulics, they all have one thing in common. Every system uses some kinds of valves. Check, or one-way valves from check valve manufacturers are important and serve special purposes. Here is information on how they work and how they can benefit your business.
In some fluid or air systems, backflow is a big problem. One-way valves from check valve manufacturers prevent backflow and possible contamination. However, there are several kinds of one-way valves.
Some one-way valves use a ball mechanism. An internal ball covers a round hole (opening). The ball is kept against a round intake port by a spring and forms a seal. As soon as liquid enters the valve, it pushes the ball forward. Once pressure from the liquid lessens, the spring forces the ball back into the intake port sealing off the flow of liquid.
These valves use doors instead of a ball to allow or block flow. The door swings open to let water in. It swings close to stop the flow, and they are commonly used inside toilet tanks for water inlet valves.
Disc valves are similar to ball valves from check valve manufacturers. A disc seals the intake port. A spring stretches as fluid enters and the disc moves to allow fluid in. When liquid stops flowing the spring compresses and disc moves back to seal off the flow.
A flexible diaphragm allows or stops the flow of liquid or air. No spring is needed. The diaphragm can change shape and flexes into position when intake pressure is greater than outtake pressure. When the situation is reversed, the diaphragm returns to its original shape.
